How to set up a bridge between two routers

If there is a need to combine routers into a single bridge, then the user will have to choose one of two available methods: by Wi-Fi or network cable. In each case, the devices will work on one network, united by the “bridge”.

To configure the bridge between two routers, we will use two ways. Each of them has certain advantages and disadvantages that are desirable to know before the start of the operation:

Wi-Fi network connection. To bind two routers into a common network, it is necessary to use the WDS or “bridge” mode, which, in fact, means the same thing. In this scenario, you can have two routers at a fairly large distance from each other, while they will have a good (not better) connection. The main advantage of the method: it is not required to lay a cable around the room. But one cannot fail to note the minus of the method: after connecting two routers via Wi-Fi, the connection can be unstable, since the speed of the wireless network will decrease. This method is usually used by people who do not want to spend extra wires in the house. It should be borne in mind that not every router has WDS support, especially for old units.
Using a network cable. This is an outdated but more reliable option. The only inconvenience is that for the connection of two routers you will have to lay an additional cable in the house, and quite long, if two devices are in different rooms. Typically, a suitable cable is included, but it is very short, and therefore you will have to additionally purchase a longer option for the operation.

The selection of the connection method depends solely on the needs of the user. Having made a choice, you can consider each of the methods in detail.

Bridge setting through Wi-Fi or WDS

To deal with the connection of several devices over the Wi-Fi network, it is advisable to use the routers of the most popular manufacturers as an example: ASUS, TP-LINK, which will be done in the future.

An important condition: a functioning main router is necessary, where the Wi-Fi network comes from. It is to it that you need to connect additional equipment. At the same time, do not worry that two equipment were purchased from different manufacturers, although it is advisable to do just that if there is an opportunity.

It is important to remember that the most stable connection can be created using compatible devices from one manufacturer. This is especially true with ASUS devices.

The first thing to take care of is a change in the settings of the main apparatus. To connect additional devices to the main equipment, it is necessary to install the statistical channel of the wireless network. If this is not done, problems may arise in both devices.

Change the channel settings is necessary due to the device to automatically select the appropriate channel when turning on. This means that when activated, the device independently occupies a free or less loaded channel. The problems with the connection begin at the moment when several devices are connected to this channel, on which there are already many devices. The fact is that in an apartment building there are many Wi-Fi points that strive to take a more profitable “goal”. The more devices on one channel, the more stable communication.

Therefore, so that there are no problems with the connection, it is necessary to choose free channels that are least used.

To understand why the channel for Wi-Fi is so important, you need to understand the basics. Now all devices are transmitting data on a wireless network to 2.4 or 5 GHz. The second option is more rare, and the latest devices work with it without interference. As a rule, preference is given to the first option, since few people want to spend extra money to buy a new router operating on 5 GHz.

Consider the frequency of 2.4 GHz. On the territory you can use channels from 1 to 13. This is even more than in some other countries. Therefore, you should not buy modems from America, because they simply will not be able to work on channels above 11.

It is within the allocated zone that we need to work to tie two routers. As you can see, there are enough options, because most users do not set up channels, because the modem does it automatically. Therefore, we have a higher chance of taking the most suitable option.

To go to the settings of the channels, it is necessary to take only a few actions:

Connect to the modem.
Open a browser.
Drive the following combination into the address line: 192.168.one.one.
Next, you need to specify the user name and password, by default it is “admin” and “admin” or “admin” and “1234”.
Now you need to find a line with channels and change the automatic search for your version.
As soon as the operation is completed, it is necessary to apply all the settings by pressing the corresponding key.

These are all preliminary operations that have to be carried out before connecting two devices.

How to combine routers through Wi-Fi

This technique of connecting two separate routers is most often used due to convenience: there is no need to touched and drill walls, laying the network cord.

As the main router, we take a representative of the TP-Link product line. P3

The “main” modem at the time of the start of configuration of the bridge should already be configured itself and “distribute” the Internet to customers.

The second important point: to connect two routers to one network, you should configure the static channel. Usually, Auto value is set by default, you need to choose one of the available in the list. As a rule, the standard channel 6, so choose the value above this.

If the second router also refers to the TP-Link family, the channel changes in the settings:

In the main menu, find the “Wireless” section (“Wireless mode”).
Next, go to the Wireless Settings tab (“Wireless Settings”).
In the window that opens, find the “Channel” item (“Channel”). Install the desired number.
Apply the changes made.

So. You Want to Hook Up a Second Router?

Next, you should configure the second router, which will be a client client in WDS mode. This requires the sequence of actions:

Enter the device settings.
Change the internal IP address. A change is needed to avoid network conflicts: there should be no devices with one IP address, otherwise a conflict will arise. If the local IP of the first router 192.168.0.1, another address from 192 is set.168.0.2 and above. It is important that both be inside the same subnet.
After applying the settings, go to the web-integer for the newly assigned IP.
Go to the settings of the wireless mode parameters in the corresponding tab.
If desired, indicate the name (“SSID”) of the second network.
In the column “Channel” (“Channel”) enter the same number as on the router number 1.
Mark the item “Turn on WDS”.
Activate the “Search” “mother” detection button.
Select the right SSID Wi-Fi connection of the leading router and click the “Connect” button.
enter password.
Apply and save data. The device will reboot.
After that, enter the menu again and check the condition. The active state of WDS should be displayed on the status page.

If the manipulations are made correctly, then the setting is completed: you connected 2 routers to one common network.

But there is one nuance: when connecting via Wi-Fi, the network will work, but if you connect the network device by the cord to the router 2, it will not go on the Internet.

To eliminate this drawback, you should turn off the 2-built DHCP server on the router so that its customers receive addressing directly from the first.

Next, go to the configuration integration and turn off the DHCP server.

The process of conjugation of routers is completed.

It is important to choose the correct place of placement of the device 2 so that the signal from the first “finishes” to it with sufficient force.

Cabel connection

The wired conjugation is possible in two ways:

In the first case, the network is created between the combined Ethernet connected to LAN ports with routes.

In the second, a cable between the WAN-Inteum of the second router and the LAN port of the first is laid.

Lan. Lan method

First, determine which of the devices will perform the head. Choose a router with an Internet Schuur coming to it.

Next, connect the main LAN port with the LAN.

Suppose that on the “leading” Internet is configured in advance. The following actions will be as follows:

Connect to the web-integer gadget number 1.
Check if the DHCP server is involved, if turned off, activate.
Save the settings.
Connect to gadget number 2.
Disconnect DHCP on it, similar to a wireless way. Address will be taken from the head router.
Also, by analogy, change the local IP address of the device.
Apply the settings and cross the configurator.
Check the status of the device. It should receive a network address from the main one and act as a wireless access point.

Lan. Wan method

The WAN port of the router 1 and the LAN port of the router 2 is connected. We assume again that the necessary settings are made on the main modem and DHCP is included.

The sequence of actions will be as follows:

We go to the Gadget 1 menu and check the work of the DHCP server. By default, the service is always included, but if inactivity, the function should be enabled and applied to the changes.
We go to the gadget 2 menu and on the Wan network tab, select the dynamic type of request for IP addressing. We save the data.
DHCP function in this case does not need to be turned off.
We check the range of local addresses of the DHCP server on both routers so that they do not intersect. For example, if the host indicates the addressing range 192.168.0.2 199, 192 should be introduced on the leader.168.0.200 254. In case of failure to fulfill this condition, addressing conflicts are possible.
We use settings. You can restart the gadget.

As a result, both of the access point will start on both, but they will become interconnected in the framework of a single subnet and allow customers to use all resources.

Methods of connection

Before strengthening the Wi-Fi signal using the second router without a wire or with it, you need to deal with the main methods of connecting network equipment.

There are two most common ways to combine adapters.

Cable equipment connection

In this case, you will have to stretch the cable between the routers. This method is used most often, since it provides the most reliable connection of devices without losing speed.

However, this connection method and disadvantages have. The fact is that the cable does not always manage to stretch. Especially if you need to do this between several houses or floors. Despite this, this method is the most stable and effective.

Wireless connection

Some people do not want to connect 2 routers into one network via cable. In this case, you can connect the devices to each other through the “air” using Wi-Fi for this.

To bind the routers using this method, you will have to use the WDS protocol. The main advantage of this method is that for its use it does not have to stretch the cables. However, there are drawbacks. An unstable data transfer speed is highlighted among the minuses.

Everyone must choose on their own which of the methods described above is to use to connect routers to each other. However, if you want to ensure that the connection is as stable as possible, it is better to use the cable connection.

Cable connection methods

Not everyone knows how to connect the second router to enhance the Wi-Fi signal using a cable. There are two ways by which this can be done.

Lan-Lan Connection

Before connecting the equipment, you need to determine which of the devices will be the main. It should be a router to which the cord of the Internet provider is connected. Then it is necessary to connect the devices among themselves with a LAN cable and sequentially perform the following actions:

Go to the web-integrator of the leading router. You can get access to it with the slop of any browser.
Check if DHCP is activated. It must be turned on in the settings.
Save the settings.
Connect to the second router and open its settings.
Disconnect in the parameters DHCP server. This is done so that the device can receive addressing from the main network adapter.
Save the changes made.

After you managed to configure the second router to enhance the Wi-Fi signal, it is necessary to check its performance. He must receive an address from the main modem. This will use it to create an access point with which you can connect to the Internet.

If you could not connect network adapters by LAN, it is necessary to check the equipment parameters and make sure that everything is really configured correctly.

Lan.Wan method

If the previous method did not help, you need to try connecting network equipment using this method. He will also help improve Wi-Fi.

First you should install the cable in the WAN-port of the main router. After that, the cord must be put in the LAN connector of an additional device. Now you need to go to the parameters of the main modem and make sure that DHCP has already been activated in it.

Go to the web-intensive modem and open the section responsible for configuring the WAN network. He is on the main menu.
Change the type IP. It is necessary to use dynamic addressing.
Save the change in parameters.

In this case, the second adapter will not have to turn off the DHCP function. It should always be turned on.

Now you need to check the local DHCP addresses. You must make sure that they are not the same and do not intersect. For example, if addressing 192 is used on the main network equipment.168.0.2, it means that the additional address should have a completely different address. This will help to avoid the appearance of problems using several adapters within the same network.

Cable connection methods

Not everyone knows how to connect the second router to enhance the Wi-Fi signal using a cable. There are two ways by which this can be done.

Lan-Lan Connection is a method that is most often used to connect several routers among themselves

Go to the web-integrator of the leading router. You can get access to it with the slop of any browser.
Check if DHCP is activated. It must be turned on in the settings.
Save the settings.
Connect to the second router and open its settings.
Disconnect in the parameters DHCP server. This is done so that the device can receive addressing from the main network adapter.
Save the changes made.

If you could not connect network adapters by LAN, it is necessary to check the equipment parameters and make sure that everything is really configured correctly.

If the previous method did not help, you need to try connecting network equipment using this method. He will also help improve Wi-Fi.

Sometimes for a wired connection of one router to another, WAN-port is used

Go to the web-intensive modem and open the section responsible for configuring the WAN network. He is on the main menu.
Change the type IP. It is necessary to use dynamic addressing.
Save the change in parameters.

In this case, the second adapter will not have to turn off the DHCP function. It should always be turned on.

An increase in the Wi-Fi coating area is one of the main reasons for using an additional router

Is it possible to use this type of connection to enhance the signal when distributing Wi-Fi

Few people know that the second router can be used as a signal amplifier.

The fact is that, when connected, an additional network adapter will be able to improve the Wi-Fi signal. The device will accept data from the main modem and distribute it to obtain access to the Internet via Wi-Fi.

This is very convenient, especially for buildings with a large area. Thus, it will be possible to use a wireless network even far from the main router.

Some users decide to use two routers in one network. However, before doing this, it is necessary to figure out how to connect two routers among themselves via Wi-Fi or by cable so that you can use the Internet.

Additionally about the settings

Weighing the advantages and disadvantages, it turns out that the physical connection according to the Lan-Wan scheme is more promising. Therefore, after the cable is connected by both routers, the first thing is to check whether the DHCP server is turned on. The new device will receive a network address in automatic mode.

If it turns out to connect the client’s device to the router, this indicates that the distribution is correct and there is no need for additional settings. If there is no connection, then it is necessary to re.contact the settings of the router.

To do this, the user needs to perform the following actions:

Introduce the IP address of the device into the address bar of the browser. There is a sticker with the inscription “IP.
Enter the written name and password that are there on the sticker on the bottom of the router.
Go to the “control panel” of the device.
Find the section “DHCP”. In some software (software), there may not be such a section separately, so you need to look at other menu items.
Go to the DHCP Settings subsection. On the example of the TP-Link router, it will look as shown in the figure below.
In the column “DHCP” put a checkmark near the “enable” item.
When the setting of the devices is completed, it is necessary to restart PC.
As for the relay, it also needs to be configured through the Network tab in the settings on the device control panel.
The “WAN” menu requires indicate “dynamic IP address”.

After these steps, you can directly proceed to setting the network.

Sometimes it happens that the connection is not possible due to the malfunction of the port of the WAN. Then you have to use the LAN-LAN scheme.

TP-Link routers

TP-Link routers are leaders in their industry and not. The manufacturer thought about the buyers of their equipment, so all devices are equipped with technology, which in itself expands the coverage area so that the client does not bother with the settings. It has the name WDS. This means that the devices can be connected together by Wi-Fi and use to the full.

To perform such a connection, you need to perform the following actions on the relay:

Go into the option of wireless regime.
The menu will have a “enable wds” item.
Then enter the name of the router. You can do this through the search if the name is unknown. The user only needs to choose a router and click “connect”. As a result, an automatic redirection in Wi-Fi settings will occur.
It remains to give the name of the access point, set the password and the type of encryption.

We use a router as a repiter

It is not always worth gathering, trying to connect a router through a router through a cable-you can do the same through Wi-Fi. For this, the second device should be able to work as a Wi-Fi repeater (aka repiter) or support WDS technology. The second router is connected to the wireless network of the first and expands it to the zone of operation of its signal. This is how it looks schematically:

On the first device in the diagram, we still do not change anything. He works in the same mode as he worked, we will simply connect to his Wi-Fi and transmit the network further. Consider the configuration of the second router in the mode of the wireless repeater mode. the repiter.

Unfortunately, not all modern routers support this operating mode. For example, my tp-Link Archer does not know how. Therefore, I will show an example of setting a repiter mode on a Wi-Fi-marchrutizer ASUS RT-N10U. It is perfect for these purposes due to a fairly low cost. The sequence of actions is as follows. Reset the settings with the Reset button. After that, you need to go to the web-integse of the apparatus using it IP 192.168.one.one.

On the main page of the web-intese, we find the line “Working hours”. By default there is a “wireless router”. We click on it and go to the page of choosing the operating mode of the device:

Here we need to put a daw on the point “Repeater mode”. Click on the button to save.

Then we should have a choice of available wireless networks:

Click on the one to which we want to connect. Below is a field for entering a password on Wi-Fi.

Enter the password and click on the “Connect” button. If you introduced it correctly, then the next step will already be the configuration of the Wi-Fi network of the repeater.

Here you need to register the network name. SSID, and in the field “Network key”. password. Click on the “Apply” button.

That’s it, we managed to connect two routers into one wireless network and you can click on the “complete” button. You can connect phones, tablets, laptops to it and check Internet access.

How to connect two routers with a cable

There are currently several ways to make the network router. The easiest and most affordable is to combine them with the cable. Although here, an unprepared person who is faced with this, questions arise. First of all, it is not clear through which ports to connect two routers, because each of them has several ports. Wan and LAN. which one to use? There are two possible schemes.

Connecting routers-LAN-LAN Connection

This method is the most correct in terms of expanding one local network. In the Lan-Lan circuit, two routers will be used in this form. The first plays the role of a router who receives the Internet from the provider and distributes it to all other clients. We will use the second router, in fact, as an ordinary switch with a Wi-Fi access point. The switching of patch cords will look like this:

That is, from the first switch we leave the LAN port and come to the LAN port of the second. At the same time, the WAN-port is not used on the second router.

But, before connecting two routers among themselves, you need to perform some settings. At the same time, we do not change anything at the first, but on the second we do the following:

There should not be two active DHCP servers in one segment of the local network. Leave it on the first router, and turn off the second. For example, I will show how this is done on the TP-Link Archer router.

After you disconnect the DHCP server on this router, client devices will not be able to receive IP from it until you connect it to the first in the scheme. If you need to connect, write down on the connected IP-address device statically and you can get into the settings.

Note: here there is an instruction how to disable a DHCP server for other models of routers.

2, change the IP address of the second router

This must be done for two reasons. Firstly, if you have two routers connected to have the same local IP address, then the network will not work normally, not knowing which of them to send packages. Secondly, in order to have access to the settings of the second router, it is advisable for him to prescribe IP from the subnet of the first.

For example, if the first router IP address 192.168.0.1, then the second should be done 192.168.0.254. Then you will always have access to the settings of both devices. Simple and convenient. Forget the settings!

After the above actions, you can connect two routers with a cable and check the operation of the local network.

Wi-Fi setting on the second router

Since we put the second router to expand the coverage area of the first, it will be necessary on it to prescribe the same Wi-Fi network name (SSID identifier) and password, as in the first.

If the devices are two.band, then duplicate the settings for both ranges.: both for 2.4 GHz, and for 5 GHz.

Tip: since you will now have two access points with the same network name and password, you need to place them so that they minimally overlap each other. Otherwise, problems may arise.

How to configure the connection of two Lan. Wan routers

This option can also be used sometimes, although it is not quite correct. Firstly, it turns out not quite a single network-from the side of the second router, the entire locker behind both devices will be visible, but from the first-no-no. This method is often used when connecting to the Internet through neighbors, or when to make the simplest division of the network into segments.

On the first router, everything is still-we connect it through the LAN port with the WAN-port of the second router. After that, the second is adjusted as a full.fledged router, with its subnet. In the Internet settings, you need to choose the option “dynamic IP address” (DHCP IPOE) on it:

It is important that the DHCP server must be included on the first router. Of course, it would be possible to get a shutter and configure everything through the statics, but this is not entirely right, and for an inexperienced user, it will be easier, faster and more convenient through the dynamics.

How to connect Wi-Fi routers

Now let’s look at how to connect two routers into one Wi-Fi network. An interesting situation has developed here today. On the one hand, the only technically correct option for today, in which you can use several routers-this is a MESH network. But this equipment is much more expensive, and therefore many cost a cheaper way-using the old and long-known WIRELESS DISTRIBUTION SYSTEM-which allows you to expand the zone by combining several Wi-Fi access points in one network without the need to connect them with a cable. On D-Link routers, this is called the Wi-Fi Client mode, ASUS is a “wireless bridge”.

I must say right away that the speed of wi-fi with this scheme can be significantly lower, but if, the choice is small, then it will go away and so.

I will show how to correctly configure such a connection on the D-Link DIR-300 router. If you have a different model, then make sure that it knows how to work with WDS and act by analogy.

We start by entering the device web-integer (D-Link uses IP address 192.168.0.one). We open the section “Wi-Fi” settings. “Client”.

A list of networks that the router sees will be displayed here and among them you need to choose the one to which we will connect and enter its password.

If the connection passes normally, then then you need to go to the WAN-DOCTION settings section, delete all existing connections there and create a new one with the “Dynamic IP” type, and select a wireless network-WLAN or WIFICLIENT (depending on the firmware) with an integer for connecting).

After that, a new line of the created connection will appear in the connection table.

Now it is necessary to save the settings of the router and restart it.

After rebooting, you can connect customer devices and check the work. If everything was done correctly, then the connection of Wi-Fi routers into one network via WDS should work. If there are still problems, then start by updating the firmware of the router. very often the case is precisely in this.

The entry was published on January 22, 2021 by the author of the XASAH in the heading General questions with the labels Lan, Wan, WDS, two routers.

Association using Lan cable

Immediately decide on which router will be “main”. Better choose a device with greater power, unless, of course, you have two identical models. There are two types of connection using the LAN-cable-Lan-Wan or Lan-Lan, but the first is more popular, so we will start with it.

Setting up connection Lan. Wan

How this type of connection works? One of the routers becomes the main one. it receives the Internet, and the second device plays the role of the secondary network and accepts data from the “main” access point.

This connection has the following advantages:

A secondary network can be controlled and limited to access to certain sites, for example, if you are worried that children cannot go to the “adult” sites.
The connection becomes more protected from extraneous intervention.
It is this method of connecting in most cases that it is recommended by specialists, since it is considered the most true and when it is used rarely arise (compared to the LAN.LAN type).

To connect Lan. Wan, make sure that when operating the main router, you can go on the Internet without interference, and the following parameters are installed in the settings (they are universal for most models):

If you are not sure that you have the same settings or do not know how to check them. perform such actions:

Enter your IP address in the browser line, and you will see the device parameters.
In the LAN section should be a checkbox near the DHCP server.
In the WAN section, the type of connection Dynamic IP is installed.

We figured out the first router, go to the second. it is better to drop all the settings on it. This is especially true if you previously used the services of another provider (he could have completely different parameters). Therefore, click on the Reset button located next to the connectors and hold it for about ten seconds, after which the basic settings will restore.

Now you need to correctly connect both devices with the cable. Basically, we use the LAN connector, in the second. the WAN cell. Check the light indicators. on the case of each of them a light bulb should be lighted near the inscriptions of the same name.

In the main router, we do not change anything else, and in the second we check whether the dynamic type of connection is established (we have already considered earlier how to do this). Do not forget to come up with a password for access to the Internet. for this you need to go into the parameters of the Wireless section, the Wireless Security Point.

Connection LAN. LAN

This type of connection is different in that here the equipment for access to the Internet is located in one network segment, and in the previous case, the second router created its separate network. For installation of LAN-LAN, in the main device, all data remain by default.

We change the parameters on the second router using the following actions:

We connect it to PC.
We go into the equipment settings through the browser, turn off the DHCP server.
We change the IP address-we increase the last number in the initial combination specified in standard settings per unit.

After that, connect both routers using a cable through the ports of LAN, in the first and main device you connect a cord for accessing the Internet.

Association of two routers through Wi-Fi

In this option, we do not need any cables to connect a pair of devices, so this method seems more attractive to many. As a result, we still have a single network, but with the addition of another access point. Thanks to it, the Wi-Fi coating area increases without loss of quality. The only requirement for such a connection is that the second router works as a relay of the main signal. Once such a function was called the repiter mode, and today in most equipment there is WDS technology.

We proceed to installing the settings. In the first and main router, we do not change anything, all parameters remain the same. You only need to check the channel number in the Wireless section (Chanel line). you will install the same value on the second model, otherwise they will not start working together.

Now our task is to configure the second device to the signal relay mode. We will consider the sequence of actions in this order as on most models of the TP-Link brand, since they are the most common among users.

Make sure that the second router supports WDS technology. this can be checked in the documents or on the manufacturer’s website. Then connect it to the computer and go through the browser to the settings.

In the WPS section, disconnect the active status, make a reboot of the router.
It is recommended to go to the DHCP section and turn off the server of the same name, since the relay function is to accept these networks, and not distribute them.
Choose a Network section and change the last number in the IP address (you can increase it by a unit) so that it does not coincide with the combination specified in the working data of the main router. After rebooting, enter a new set of numbers to enter the parameters.
Open wireless:

Change Network Name. come up with a name for an access point so that you know which device you connect.
We go to Chanel and select the same number as in the basic Internet settings.
Put a checkmark opposite Enable WDS Briding. so we will turn on the operating mode in the form.
Now that work has begun in new mode, new settings will appear, so we click on Survey to search for a network to which we will connect.
From the search results, select the main access point, click Connect. In the window that appears, it remains only to install the type of encryption (Key Type) and register a password for entering the Internet.

So you have completed all the necessary actions to configure wireless communication between two routers in the same network. If you want to make sure you did it right, then Run will be indicated on the main page on the WDS Status line.

As you can see, you can combine two routers in several ways, and you can choose the most convenient option for your home. After installing the second access point, you will significantly increase the Wi-Fi coating area without losing the speed and quality of the connection-these indicators will be at the height regardless of which part of the room you use the Internet.

Lan /Lan wired connection procedure

The network cable connects additional to the main router through LAN ports. The main device is traditionally the one to which the wire of the Internet provider stretches. After entering access to the world network on the first device (according to the instructions of a particular device), you need to configure the connection to the following devices. It must be included in it! You can check this item at the DHCP / DHCP Settings menu. And for the second router, on the contrary, after turning on the DHCP server, be sure to turn off. The next step is important to change the IP address of the second device so that it is with the main one in the same subnet. For example, the first IP address 190.160.one.one. Then indicate the secondary address 190.160.one.2. Save the entered data and reload devices, after which a secondary router will become an access point distributing access to the Internet in its radius.

The network cable extends from the port of the LAN main router to Wan/Internet additional routers. At the same time, the system settings are as follows:

At the DHCP / DHCP Settings item, click the “VKL” button opposite the DHCP server column. Save.
Install a dynamic connection in the network of the network/Wandobavka device. Save.
Turn on the DHCP server option.

If in the future it is planned to use LAN ports of the second router, then it is important to configure their IP address so that they differ from the addresses of the first. If all actions are performed correctly, then both routers will be in working condition, providing access to the world web from one network.

Or can distribute the Internet through electrical wiring as an alternative method

In addition to standard methods of creating an Internet network, there is an alternative way-transmitting the Internet by electrical wiring using HomePlug AV technology. This requires PowerLine adapters that are included in the outlet and transmit data to different devices like Wi-Fi or network cable. Roughly speaking, this is the Internet from the outlet.

This method of Internet connection allows you to exchange data through an electric network at a distance of up to 300 meters. The above radius of the coating is quite suitable for both the apartment and a small house. There are two types of adapters:

They differ in the speed of the Internet. HomePlug AV produces Internet speed 200, 500 and 600 Mbit/s. However, in reality, the speed does not exceed 280 Mbit/s. This is not the best type of connection for games or watching video on the Internet. Internet speed with Homeplug AV2 can increase up to 1200 Mbit/s, but in fact it is not more than 600 Mbit/s. HomePlug AV2 adapters need high.quality electrical wiring and mandatory grounding. So that the speed is maximum need copper wiring of better quality.

PowerLine-adapters do not work without a pre-tuned router or modem, as they only enhance the signal of other devices and expand the radius of their actions and are not able to install an Internet connection with the provider. To expand the area of the wireless network coating, you need to connect the appropriate adapter in the outlet next to the router and connect them with a network cable. After that, in other rooms, if necessary, you can connect more adapters (up to 64 pieces in one network), which will distribute Wi-Fi connected devices, expanding the radius of distribution of the wireless network of the first router.

In the event that the consumer is preferable to a Wi-Fi connection, but the connection by means of a network cable, then simple adapters with the RJ-45 connector are suitable. Similarly to the case with routers, you can simultaneously use adapters from different companies. But for the convenience of their settings, it is preferable to connect the adapters of one manufacturer to a single network. In this case, the setting may be reduced to pressing one button.
