IPhone does not connect to Wi-Fi Mikrotik. Current TX Power

Subtle. Mikrotik, Wi-Fi and iPad

Apparently something happened to me with Google, so I turn to the collective mind of the forum. Introductory as follows: Er-Telecom, Microtics RB951UI-2HND distributes the Internet through the apartment. Everything works stably, except for two iPad 2 tablets. Symptoms. There is a symbol of connection to Wi-Fi, but there is no access to the Internet. It is treated by turning off and after a while turning on Wi-Fi on the tablet. There are no problems on the iPad Air. Laptops and Smart-TV receive the Internet without problems. In general, the microtics like stability and glugalness, but two iPad are upset. Replace the tablets not to offer;) Google did not help. The people are faced with the problem, but there is no description of the solution. Options to “change the country” or “hard to set only n” tried. Update does not help. Someone had to face a problem? Share a solution, please!

Thanks for the link. I have already read this branch. Tested the disconnection of geolocation, encryption WPA2 2 PSK. Really helps forced planting of the network on g. But the number of customers on the network is too large to work normally in this standard in this standard. No problem was observed on Netgira who used to use.

Collins.www.NN.ru/ recently here or on the Internet wrote a post, which is sometimes bad when the Wi-Fi router allows thin settings. Just your situation. There is a technique for finding a malfunction.

I would have slaughtered the channel. You have a watt Wi-Fi transmitter, any neighbor will “bury”.

About the number of customers. I wrote about my network, I have two families live in my three.rute in a three.rute and three tablets, two computer and two Smart TVs can work at the same time on watching a video. The previous router stumbled on this, after which a microat was placed. It is possible that some kind of Zuhel kinetik gig would suit me more because of a simple hum.

he did not feel the current of the microtics 🙂 Better on the of. Forum forum.Mikrotik.COM/ViewForum.PHP?F = 1

there normis as of. The representative and citizen of the Baltic states, understands Russian

Eh, I didn’t have time. There was a similar problem with Waffles, it turned out that the devices did not understand the microtics when it goes to the 13th Wi-Fi channel. You are forced to 1-12 for 1-12 and the problem is solved, you poked from the car mode to the 1st (minimum channel frequency) and forgot. Probably the devices do not fully support the European grid

This is a glitch in the old Bratkovsky farmvar of iPad and poppies. Turn on 802.11QOS/WMM in router settings. The rest of your working Wi-Fi devices most likely slid until 802.11G mode, t.to. This is the only correct way to get around this erroneous configuration on the side of the access point. This option should not be available to users at all, t.to. It makes no sense, but t.to. it is available, then users make mistakes through one. Transition to 802.11g helped you because it initially does not have QOS support. My mother’s masters have recently put a microtic with such settings at home. As a result, my gift to her, the brand new Mac BookPro, refused to work with him. I had to waste time and understand. T.to. The bropage has long been aware of this error, then in new devices they try to include a fix for this cockroach (although sometimes they have forgotten and have to remind).

We try to forget the network on the iPhone/iPad and connect to Wi-Fi again

The “Forgetting this network” function does not rarely help get rid of various problems with the connection. Especially, this method is relevant when the device does not connect after changing the router settings. For example, after changing the password of the Wi-Fi network. And the error “failed to connect to the network” appears, or there is a constant connection.

Just go to Wi-Fi settings and click on a problem network. Then click on “Forget this network” and confirm the action by pressing the “Forget” button.

After that, try to connect again, indicating the password.

We make a full reset of network settings on iOS device

Another solution that completely removes all network settings on the iPhone and allows you to get rid of many malfunctions related to the Internet connection and restore Wi-Fi work.

In the settings, we open the section “Basic”. “reset” and click on “Reset network settings”. Then we confirm the reset.

After that, you can try to connect your iPad, iPhone to Wi-Fi network. If the problem remains, and he will not want to connect, then most likely the matter is in the settings of the router (which, I hope, you have already rebooted).

Mikrotik as a Wi-Fi client

Perhaps everyone will sooner or later faces situations, if either the Internet provider carries out technical work, or problems arise on its line-and as a result of the home Internet stops working. In this case, mobile Internet comes to the rescue from a cell operator. All modern smartphones support the functionality of “access points”-when a mobile device can act as an access point, and other devices-connect to it in the usual way by Wi-Fi.

But what to do if your computer does not have a Wi-Fi adapter, and the only option is to connect a cable from a higher router? Using this instructions, you can configure Mikrotik in the Wi-Fi client mode-so that this equipment receives the Internet from a smartphone and distributes it to all other devices.

If your microtics has already been configured in advance-most likely any bridge with its own addressing has already been created on it. By default it is Bridge (with addressing 192.168.88.1/24). The addresses from the registered pool will receive all the devices connected to the intenses of this Bridge.

Next, you need to raise the Internet on the microtics itself.

Go on your smartphone in the settings of the “Access point / Mobile access point / Personal access point” (on different models of devices, the option may differ). Write the desired name of the Wi-Fi network and password (we have Test_Client and 12345678). Turn on the access point.

Go to the microtics settings, Wireless tab.

In the Security Profiles menu we create a profile, prescribe a password in it, which is registered at the smartphone access point.

In the Wi-Fi Interface menu, open Wlan1, Wireless tab: Mode-set stations. SSID value is an identical smartphone access point Name. The value of Security Profile is a previously created password profile.

Then it remains only to set up the distribution of the Internet to the microtics from your access point.

In the IP section.DHCP Client add a new parameter: Select Wlan1 as an intense (this integration should not be in any bridge), in Add Default Route-Yes.

Or apply to the New Terminal Microtics Script: /IP DHCP-Client Add Interface = Wlan1 Disabled = No

Now, when the wired Internet is turned off, if the smartphone includes a configured access point, a microtics and all the devices behind it will go on the Internet through it.

Data Rates

The settings of the channel speeds are set here.

  • Supported Rates. channel speeds that are maintained by a wireless intensity;
  • Basic Rates. channel speeds to which service traffic is transmitted.

One of the settings: you can remove all the checkmarks from the B-standards, the devices will be able to connect only on the more speedy standards G and N N. In this case, you need to remove all the checkmarks from the “Basic Rates B”. permitted modulations for official traffic of standard b. “Supported Rates a/G”. We put all the checkmarks, and in “Basic Rates A/G” we leave permissible modulations for official traffic only 6 MBPS.

But if your device is old (the old radio module does not support high-speed standards). it will not be able to connect with such a setting. If we select N-ALy mode for devices (on the Wireless tab, Band field). then all the checkmarks on this tab are removed.

In the vast majority of cases there is no need to change anything.

Advanced

Area. allows you to create a group and include wireless devices in it, and then use certain rules for this group and all devices included in it, instead of creating separate rules for each device. This value is filled at the access point, and can be compared with the rules in Connect-List.

Max Station Count. the number of connected customers, including WDS connection. Relevant only for AP modes.

Distance. maximum permissible distance of wireless lens. Meanings:

  • Dynamic. auto.navigation;
  • Indoor. indoor work;
  • Distance in kilometers. When indicating this parameter, it is recommended to indicate not the exact distance between the devices (by cards or GPS), but the value is more by 10-20% of this distance;

If customers are in the same room and at about one distance, let’s say everything within a radius of 20 meters from the access point, then indicate “indoors” if you have an open area of ​​the field or conference room and customers are at different distances of more than 0-20 meters, then indicate The meaning “Dynamic”. Well, the third if the clients are at the same distance, let’s say 1 km, then indicate so. This option allows Mikrotik for a sewn.in algorithm to calculate whether the package has been delivered to the desired addressee.

Since the point is indoor and customers at a short distance. “indoor”.

Noise Floor Threshhold. Manual adjustment of noise level on the channel (DB). In fact, this is the minimum SNR value for wireless connection. If the connection characteristics are worse than this value, the connection will not be installed (or will be torn). This function only works on ATHOROS production chipsets, starting with AR5212 and more new. Most often, values ​​are set “-92107”. You can also determine it yourself: measure the noise level and reduce this figure by 5-10 units. For example: the actual noise level.107, therefore, we set the value.100.

The setting is specific. We leave the field empty.

Periodic Calibration. Periodic calibration of Link. The values ​​of Default and Enable include this option if the interval is set in the Calibration Interval field. DISABLED value disconnects this function. This function works only on atheros production chipsets.The Wi-Fi chip heats up during its work, and because of this, the frequency can move off a little, accordingly turn on this option. Leave the next field equal to one minute. Frequency calibration will occur every minute.

We put “Enable”. Function in version 6.38RC38 has already been drunk.

Calibration Interval. The frequency of recalion (DD: MM: SS). With a value of 00:00:00, the recalibation is disabled.

Put 1 minute. Function in version 6.38RC38 has already been drunk.

Burst Time. time (in microseconds) during which data can be continuously. This function only works on chipsets AR5000, AR5001X, AR5001X.

On off. the forum is recommended to be left as it is. The field is empty.

HW. Retries. the number of attempts to send the package before sending is recognized as unsuccessful. If this value is exceeded, the connection speed with the remote device will be reduced, after which attempts to transfer the package will be made again. If the minimum connection speed was reached, but the package was not transferred, the transmission attempts are suspended for the time indicated in the ON Fail Retry Time parameter. After that, attempts to transmit the package will again be made until the time specified in the Frame Lifetime parameter expires, or the remote device will not be disconnected by exceeding the Disconnect Timeout parameter.

Values ​​from 1 to 5. The speed of the network is higher, however, for subscribers with a poor signal, communication stability will worsen (loss of packages, frequent disconect. Values ​​from 5 to 10. golden mean. Values ​​from 10 to 15. The maximum guarantee of data delivery, but in the problem network, the speed will slow down. Based on this, it is preferable to set the average values ​​for the base station (5-7), and the maximum is placed for the point of the point. fifteen.

HW. Fragmentation Threshold. sets the maximum size of a fragment of the data package transmitted via Wi-Fi. Large packages will be divided into such fragments to increase reliability and communication speed. Used only for 802.eleven. Setting, which may help with Links over long distances, but we do not use fragmentation.

The setting is specific. We leave the field empty.

HW. Protection Mode. Frame protection mode (protection against hidden node). This item can help in solving the problem of the hidden node if you specify “RTS CTS”. 802.11 (aka wi-fi). This is a single data transfer environment (such as a Hab device), and in the standard 802.11 indicated that customers themselves determine with each other who and when will make a record, but there is one nuance. This condition will only work if customers see each other directly. If two clients begin to write at the same time, then we get a collision.

iphone, does, connect, wi-fi

As an example, imagine a certain field (that which is on the Windows XP desktop). It contains an access point in the figure of the red point, and its radius is pale red. And also: client1 (a), client2 (b), client3 (s).

Client1 and Client2 can be normal participants and work on the network without failures, but because of the client3 there may be problems for everyone, the fact is that client1 and client2 can communicate directly and determine which of them will broadcast in this period time. But client3 does not see more than one of the participants in our network, and can safely broadcast at any time even at the time when client1 or client2 will also broadcast, because of this, conflicts appear.

In Mikrotik, the value of “RTS CTS” means. “The access point itself will manage, to whom to broadcast at the moment” that will solve the problem of a hidden node. This parameter will slightly reduce the throughput and increase the load on the access point.

HW. Protection Threshold. The threshold size of the frame in which the HW function should be included. Protection Mode for a wireless integration. Value 0. The function is active for all frames.

Speed ​​restriction in the guest network

There can be many guests, and the outgoing channel is not rubber, especially since modern mobile devices allow you to view the video in high resolutions, which can lead to an increased load on the network. Therefore, we will act simply. we will limit the speed of the guest network, we will not produce any difficult settings, we will simply make one restriction on all, how it will be shared between customers does not particularly worry.

The queues are used to limit traffic. Queues, note that Fasttack should be disconnected for the work of the queues. Let’s go to Queues. Simple Queues and create a simple queue. In the Target field, we indicate the guest network intese. Bridge2, DST. Internet access Interais, in our case Ether5. In Max Limit, we indicate the restrictions for incoming and outgoing traffic, we put 10 Mbps each.

In the terminal:

Now we will connect again and check the work of restrictions, it is easy to make sure that everything works as it was conceived:

As you can see, setting a guest Wi-Fi network on Mikrotik equipment is completely easy, and the wide Routeros capabilities make it possible to significantly increase its level of security, having limited the guests to the guests network capabilities.

You can learn how to configure Mikrotik from scratch or systematize existing knowledge in an in.depth course in administering Mikrotik. The author of the course, the certified Mikrotik coach Dmitry Skoronov personally checks laboratory work and controls the progress of each of his students. Three times more information than in the vendor program of MTCNA, more than 20 hours of practice and access.

Notes of IT specialist

Wi-Fi in Mikrotik routers is quite an ambiguous topic, on the one hand the number of publications devoted to it is quite large, but on the other hand, most of them are a simple listing of all the settings present in the router with a brief description, without explanations about their appointment, need, or,,,,,,,,,,,,,, Keeping On the contrary, unnecessary. Therefore, in our article we will focus on practical application and options that you really may need in everyday activity. And also give the necessary theoretical minimum to understand the meaning of individual settings.

You can learn how to configure Mikrotik from scratch or systematize existing knowledge in an in.depth course in administering Mikrotik. The author of the course, the certified Mikrotik coach Dmitry Skoronov personally checks laboratory work and controls the progress of each of his students. Three times more information than in the vendor program of MTCNA, more than 20 hours of practice and access.

We will immediately make a brief retreat so that then no one has misunderstanding and disappointment. In part of Wi-Fi, most of the Mikrotik routers are seriously inferior even by inexpensive household routers, this is due to an obsolete hardware platform that does not support many modern standards and technologies. Therefore, if you need a really productive Wi-Fi network, you should use the equipment specially designed for this for this. access points, leaving the router his main tasks.

It should also be understood that it is almost unrealistic to achieve productive work from Wi-Fi networks in conditions of dense urban development, wireless networks, especially in the 2.4 GHz range are very strongly overloaded, and a large number of transmitters, often twisted at maximum power, make the etheric situation extremely unfavorable. In addition, wireless communication. This is a separated environment, if each consumer receives its own channel at least 100 Mbit/s width through the cable, then even the clients working in ideal external conditions will share the only 150 Mbps/s wireless channel.

Therefore, connect by Wi-Fi demanding to the throughput of the device network, especially multimedia. This is not the best idea. Wherever possible, you should use a cable connection. As for most models of Mikrotik routers, they are well suitable for organizing wireless networks designed for a small load in offices, compensating for all the shortcomings of the obsolete wireless platform with wide Routeros capabilities, which make it possible to very flexibly configure the parameters of the wireless network and the rules for accessing it.

All Routeros wireless settings are located in the Wireless section, opening which we will see a list of wireless intenses, depending on the model of the router there will be one (2.4 GHz) or two (2.4 GHz 5 GHz). Most settings for both ranges are the same, so we will consider them in relation to the range of 2.4 GHz, making the necessary digressions where the parameters specific for the range 5 GHz appear.

To configure, we will open the necessary integer and immediately switch to the Wireless bookmark, on which we turn on the extended mode. Advanced Mode.

Now let’s move on to the consideration of the first settings unit, which is responsible for the operating mode of the access point and the frequency range used.

Mode option is responsible for the operating mode of the wireless device. In our case, this is AP Bridge. The mode of the transparent access point, we will consider no other regimes within this article.

Band. Wireless network work standards. For a range of 2.4 GHz are available B, G and N, for 5 GHz. A, N and AC. Standards A and B have not been found for a long time, so N and AC are relevant, there may also be a device with adapters of the standard G. Therefore, for the range of 2.4 GHz, the best choice will be 2GHZ-OLY-N, for 5 GHz. 5GHZ-ONLY-AC or 5GHZ-N/AC, depending on the Park of User Devices. As for the devices of the standard G, if there is a need to use them, then the creation of a separate wireless network for them will be a more correct choice.

Frequency. channel frequency. You can, of course, put in Auto and forget, but in modern conditions this is not the best solution. Let’s look at the example of the etheric situation in an apartment building. Two most powerful networks on the first channel do not take into account, these are our two own points: home and test.

��MikroTik MTCNA. Wireless AP & Client Configuration

As you can see, everything is not very good, if not differently. The edges of the range are more or less free, while choosing the beginning is more preferable, both in the air of the environment and for compatibility, many devices, for example, Apple products do not work above the 11th channel.

Well, let’s not forget about the classics for 2.4 GHz: 1. 6. 11 (frequency 2412. 2437. 2432), it is precisely these non.overturning channels to choose for work. And even if we don’t get better from this, then we will at least not do it worse than everyone else, although in that chaos what is happening in apartment buildings and office centers is a rather weak argument.

Real trouble of the range of 2.4 GHz. wide 40 mHz channels, which use two adjacent 20 MHz of the canal, and since the channels are shifted relative to each other by 5 MHz, it turns out a shift for 4 channels, t.e. 15 or 610. At the same time, the main one is one 20 MHz channel, in which all service information is transmitted, and an additional 20 MHz channel is used only when the main bandwidth begins to lack. And if your main subscribers can only work with a 20 MHz channel (most mobile devices), but your point works on 40 MHz, then you will only interfere with your neighbors, without any benefit for yourself.

Correct the problem with connecting some Wi-Fi devices to the Mikrotik router

We have a Mikrotik Hap Lite Classic (RB941-2nd) router and the problem: some devices are not connected via Wi-Fi, while in logs the error “Disconnected, Receved Disassoc: Sending Station Leaving”.

Here are all the actions that I took to eliminate this problem:

  • Increased the IP addresses for more connected devices. To do this, go in the router settings (it is better to use WinBox) IP.Pool.In the Pools tab, clatter twice on a line with the name “Default-DHCP” (if the settings are standard). In the window that appears in the Addresses line, increase the range, for example 192.168.88.100-192.168.88.254
  • TKIP turned off the Security Profiles Wi-Fi Inte Wee. We go to Wireless for this. Security Profiles tab. Climat twice on a line with the name “Default”. In the window that opens in the General tab, there should only be opposite “WPA2 PSK” and two points “AES COM” (everything is as in the screenshot below)
  • Turned on WMM. There in Wireless. Wi-Fi Interface tab. Twice lay on a line with the name “Wlan1”. In the window opened Wireless tab. If there is a “Advanced Mode” button on the left, then click it, if the Simple Mode button, then read the WMM Support item further and put it “Enabled” (for convenience a screenshot below)
  • Turned on the channel only with a frequency of 20MHz. In the same Wireless window. Wi-Fi Interface tab. Line “Wlan1”. Wireless tab. CHANNEL WIDTH Point “20 MHZ”.
  • Included all speed modes in Data Rates. Wireless. Wi-Fi Interface tab. Line “Wlan1”. Data Rates tab. Select “Configured” and put marks on all speed modes.
  • There is another recommendation that can help a heap, this is a channel change. Wireless. Wi-Fi Interface tab. Line “Wlan1”. Wireless tab. Frequency point select another frequency (how to choose the correct channel here)
iphone, does, connect, wi-fi

I hope I helped in the issue of connecting some devices (Apple devices, Wi-Fi outlets and other Wi-Fi smart home devices, vacuum cleaners, other household appliances with Wi-Fi and the like) to the Mikrotik router for Wi-Fi.

Share an article in social. networks. Write the Комментарии и мнения владельцев what method has helped and are there any more ways to correct this problem.

We go to the next Wireless tab.

  • SSID-the name of our Wi-Fi network.
  • Frequency Mode-regulates a set of available frequencies and capacity of the transmitter depending on the country, I recommend choosing regulatory-domain in order to avoid even hypothetical problems from regulatory organs.
  • Country. Actually, we choose the country of being, in our case, this is Russia2.

On this tab, it is not recommended to change anything more without the need.

If there is still a desire to set the channel manually, then this is done in the Frequency parameter.

Frequency is Wi-Fi broadcasting (in home routers this is called a channel). In our case, Auto is exhibited, each time when the router is rebooted, he automatically searches for the least loaded frequency and begins to broadcast on it.

Channel Wi-Fi Lower frequency Central frequency Upper frequency
one 2401 2412 2423
2 2406 2417 2428
3 2411 2422 2433
four 2416 2427 238
5 2421 2432 2443
6 2426 2437 2448
7 2431 2442 2453
eight 2436 2447 2458
9 2441 2452 2463
ten 2446 2457 2468
eleven 2451 2462 2473
12 2456 2467 2478
13 2461 2472 2483

If you carefully look at this table, you can notice that the lower and upper frequencies of different channels intersect, so it is not recommended to choose the next channel, when busy with the desired. information can be found in Google

We move on, the Data Rates tab.

We will leave the value in Default, t.to. We want to achieve Wi-Fi work on the maximum number of devices. If you choose ConfigURED, you can turn off low transmission speeds.

Here it is worth mentioning the big problem of Wi-Fi technology itself-all Wi-Fi devices always work at the speed of the slowest of the devices connected to this network, T.e. If you have 3 new laptops on the network, connected at a speed of 54 Mbps and you decided to reanimate the old mammoth from the 90s or the beginning of the 00s and connect it to Wi-Fi at a speed of 5 Mbps, then all laptops will actually work at this speed.

Setting up and optimization of Wi-Fi 5GHZ range on Mikrotik

The setting of the 5th gigaucheal range is not very different from the setting of 2 gigacter, so we consider only the differences.

Wireless tab

In fact, this is the only settings tab that differs for 5GHZ. The remaining settings are made by analogy with the setting of 2GHz.

Band: 5GHZ-A/N/AC all protocols to support all devices.

Channel Width: 20/40/80MHz EEEC means that the farther we are from the point. the lower the width of the channel and the less transmission speed, but it will remain as better as possible.

The remaining 5GHZ Wi-Fi tabs in a microtics

We set up all other tabs in the same way as 2GHZ Wi-Fi. There is no difference.

Mikrotik tricks for perfect Wi-Fi and Internet

I will share with you one interesting trick that will easily solve the problem of working with Wi-Fi and the Internet in your office or to the apartment completely. And the name of this cunning is Queues.

With Queues, we can remove the problem of torrents, downloaders, and so on. The problem is very famous, but let’s look at the example.

You calmly view the news on the Internet, go from the site to the site and suddenly your colleague/friend/child decides to download something from torrent/update the game/update Windows. Naturally, you will begin delays in the opening of sites, and if you talked on video communication or watched TV through IP-television, or maybe YouTube, then comfort falls to zero. All your speed was taken by the downloader.

To prevent this from happening, we will configure the division of traffic by the need and programmers of Mikrotik hid this function from you in Queues. the line of traffic.

Let’s create a rule of traffic to properly prioritize traffic so that it shares at the required speed for each client’s client.

In all limits, we set the speed of tariff speed.7-10%, otherwise the restriction will not work. Burst Time is better to put 0-2 seconds.

In the Advanced tab you need to choose everything as shown in the screenshot below.

Namely, for Target Upload we select Queue Type “PCQ-UPLOAD-Default”, and for Target Download, select “PCQ-Download-Default”.

To check the work of the traffic queue, you can try to download something on the computer and at the same time go to YouTube and start the video in maximum quality on another device. There will be no more problem with work in such a scenario.
