How to Connect the Internet to a Computer via Modem

Android phone as a modem for computer via USB cable

It’s no secret that you can share your phone’s Internet connection with other mobile devices and computers. And in this article, I’ll show you how to use your Android phone as a modem for your computer, or laptop. When connecting via USB cable. This scheme is suitable primarily for desktop computers that do not have Wi-Fi module. And we can’t connect them to a Wi-Fi access point, which can also be launched on the phone.

Almost all Android smartphones can distribute mobile Internet (in modem mode) via Wi-Fi, Bluetooth, or USB cable. How to set up a Wi-Fi hotspot, I have already shown in these articles:

But if you have a PC, or the Wi-Fi on your laptop isn’t working, then you simply won’t be able to connect your computer to the Wi-Fi network. You can use a USB cable in this case. Connect your phone to your computer, and set your phone to “USB modem” mode. And the computer will access the Internet via phone (via mobile operator).

When the phone works as a modem via cable, it is immediately infected from the computer. And if you use it as a Wi-Fi access point, it runs out of battery very quickly and you need to connect it to the charger all the time.

I checked it on a Samsung Galaxy J5. It is very simple. You do not need to install any drivers on your computer, create connections, etc. Д. Simply turn on the phone mobile data (Internet via EDGE, 3G, 4G). Connect it to PC via USB and activate “USB-Modem” mode in the settings.

connect, internet, computer, modem

I think that this function also works on all phones that run on Android. I can’t check it now on phones from Huawei, Xiaomi, Lenovo, Sony, LG, etc. Д., But if there are any differences in settings and names, they are not critical.

Transfer the Internet from the computer (USB modem) to the router

Disconnect the modem connection on the computer (disconnect from the Internet).

Use a network cable to connect the computer to the router. On a computer or laptop network cable into the network card slot, and on the router to the WAN (Internet) port. I would like to point out that your router may be different. No big deal. Here is the connection diagram:

Next, on the computer right-click on the icon on the Internet connection, and select the Network and Sharing Center. Next, choose “Change Adapter Settings”.

Then right click on the connection, through which you connect to the Internet (via a 3G/4G modem), and select Properties. The connection itself may have the name of your operator. Or just “Phone Connection”, as I have.

In the new window click on the tab Access. There, check the box next to “Allow other network users to use this computer‘s Internet connection” In the drop-down list, select “Local Area Connection” (in Windows 10. Ethernet). Press Ok.

If you were connected to the Internet, you will see a message saying that the changes will take effect after you reconnect to the Internet. Just disconnect from the Internet, and reconnect. If your connection was disconnected, reconnect to the Internet. You should see “Shared” next to your connection.

In the “Local Area Connection” properties will be written IP address and netmask. That’s how it should be, don’t change it.

Connect to the Internet via a modem, and the router automatically receives the Internet from the computer (in my case the laptop). If your router is set to factory default, the default connection type is Dynamic IP. This is how it should be, since the router automatically obtains an IP from the computer.

You can then connect to the router via Wi-Fi or cable and surf the net. If the Internet via a router does not work, then first try to restart it. If this does not help, reboot the laptop and reconnect to the Internet. Turn off your computer antivirus (firewall).

It worked right away. I connected to the router through the phone TP-LInk, went into its settings (the tab where you specify the settings for connecting to the Internet), and there I saw that the router has received an IP-address from a laptop. And that means that everything works.

My router was distributing the Internet, which I got from a laptop, which was connected to the Internet via a 3G USB modem from Intertelecom.

How to connect a internet modem to your computer

After the router receives and distributes the Internet, you can change other settings of the router. For example, configure the Wi-Fi network, set a password on Wi-Fi.

Router connection errors to the Internet

Connecting without internet access

One of the most common errors, which causes confusion among users, is the inscription “No access to the Internet” or “Limited”. At the same time no page in the browser is not loaded. In the initial setup of the router, the most common causes of this phenomenon are incorrect data entry by the ISP (see. Above step 4). For example, when you choose the wrong type of connection, enter your username or password incorrectly, or enter other incorrect data. Often users enter the control panel password instead of the ISP password, which leads to this result. In this case, call your provider and ask him what you need to enter in the wizard.But this is not the only reason for connecting without access to the Internet. The problem may also be hidden on the ISP’s side, if they do some technical work or there is a breakdown in your home. The problem can also be hidden in your computer or router, so call your ISP and you will find out all of these things at once. If there are no technical problems, your provider will check whether your device receives transmitted packets of information. If it does not, you will be given specific recommendations on how to work with your router or computer.

Internet connection through the router is missing

If after the first setup the Internet worked fine, and then began to disappear, this has its own explanation. First, you’ll need to see if the internet is failing over cable or Wi-Fi. If both are missing, then unplug the ISP cable from the router and plug it into your computer to check. No problems with a direct connection indicates a problem with the router. A reboot, firmware upgrade, or factory reset may help. If the Wi-Fi signal is lost, then the device is far from the router, between the router and router there is a serious interference, or the bandwidth is overloaded. The first and second problems can be solved by other location of the router in the apartment or by installing a repeater, and the problem with congestion is solved by changing the frequency or selecting a different channel (is done in the control panel in the wireless networks section).Other causes of signal loss cannot be excluded. Sometimes the problem occurs on the ISP side, leading to frequent interruptions in communication during the day. The cause can also be a problem with a particular device (Wi-Fi adapter, network connector, network cable). Other Internet-connected devices in your home can help you make sure.Despite the fact that different router models have their own peculiarities of connection, understanding the connection diagram will help you to quickly deal with any model. Knowing the connection errors will also help you to quickly find the cause of failure and eliminate it most often without the tedious dialing to the provider or calling a wizard at home.

Connecting a USB modem to your tablet

USB-modem can be connected to the tablet on Android or iOS, if it has a built-in 3G-module and interactive settings for the mobile network. It is not difficult to identify such a tablet. It has a tray for the SIM card.

If there is no tray for SIM card, then the connection of the modem will require root rights and installation of third party software. We will not touch this topic in this article, as it is too extensive and requires a certain amount of experience and skill from the user.

Switching to “Modem only” mode

Your tablet will by default recognize your modem as USB storage device, i.E. As USB flash drive. To fix this, you need to:

  • Connect the modem to a PC with the firmware installed.
  • Run the utility to configure the modem.
  • Select “Modem only” mode. Usually it is on the main settings page, but for some manufacturers it can be located in “Mode” or “Settings” menu.

ZTE and Huawei modems can be switched in the desired mode with the help of third party software. For this purpose you need to download the Mode Switcher utility. It has only one window, at the bottom of which you will see a “Modem Only” button. Click on it.

Some utilities provide only modem mode translation without additional settings

Adapter for the tablet

Obviously, the tablet does not have a full-size USB port. Android tablets are usually equipped with a microUSB connector. To connect the modem to it, you will need an OTG-cable or an adapter. It is included in the package with some modems. If you do not have an adapter, you can buy it at any electronics store at a cost of 200. On one side it has a standard USB plug, and on the other side. A microUSB plug. Connect the modem from the USB side and insert the other side of the adapter into the slot of the tablet.

OTG cables are sometimes available as a compact adapter without a cord

Ipad owners will need to purchase a USB-Lightning adapter. It is more rare, so you may have to visit your city’s re:Store or order the accessory in an online store.

Only those USB-modems that support Mac OS X and mobile iOS will work with the iPad. For more information, see the data sheet on the package or the manufacturer’s website.

The cable designed for the camera connection will also fit

connect, internet, computer, modem

Armed with an adapter, connect the modem to the tablet and wait until the LED lamp on the modem stops flashing. Now you can proceed to the setting.

Network Setup

  • Open “Settings”. “Network”. “Advanced”.
  • Select APN Hotspots.
  • If you bought a modem from an operator, all the data will already be entered here. It is enough to press “Connect”. If you bought the modem separately from the SIM card, then you have to manually enter the data from the operator: APN (or “Dialing number”), username and password. They must be specified in the contract with the Internet Service Provider.
  • Reboot your tablet. After rebooting you will see a 3G indicator light at the top of the screen.
  • Open “Settings”. “Cellular”.
  • Turn on “Cellular data”.
  • Enter the “Cellular Data” menu. If the modem is provided by an operator together with a sim card, all fields must be already filled in. If not, then fill them out yourself. You need to fill in the first three lines: APN, “Username” and “Password”.
  • Exit this menu. If you have entered everything correctly, then a 3G/4G icon will appear at the top.

Connection problems and troubleshooting

There are many reasons for problems with accessing the Internet. In most cases they are related to provider’s work or software failure.

ADSL indicator has stopped lighting

If the LED is not lit permanently, but only blinks intermittently, it is due to a lack of signal on the line. It is recommended to check with your provider if any technical works are carried out at the moment. If necessary, try to reboot the device:

  • Find the Reset button on the back of the router.
  • Using a sharp object, pinch it for 5-10 seconds.
  • Wait until the indication goes out completely and then activate again.

No connection

Lack of connection may be due to incorrectly configured connection settings. It is recommended to contact your provider to get more accurate network settings.

Express solution is possible by reconfiguring the modem, uninstalling and reinstalling the drivers.

Low speed of data transfer

Low speed of transfer through the ADSL leased line is possible because of the wireless adapter. If the device is not new, it can only work with obsolete standards, which provide speeds up to 10 Mbps. The only option is to buy another router.

Low transfer rate of USB modems may indicate that the device has switched to another network, for example 3G.

It is characterized by a bandwidth of only 3.6 Mbit/s. If the client is in the countryside, it is possible to contact the operator to recalculate the coverage map.

Computer does not see modem

Here the solution is simple: when there is a software failure of the operating system components, it is enough to reboot the computer.

If the problem persists, you will need to reinstall the drivers for the Windows USB ports and the external network adapter itself.

There is nothing complicated about connecting and setting up a modem. The main thing is to choose the right device that can provide a stable signal and high speed. If you encounter connection problems, try first to restart your PC and router, and if the problem persists, reinstall the drivers. If no action brought no results, then it is worth to contact.

At this point we have finished configuring the USB. Modem to the Internet, but this is not all modem settings. Read about these settings in the following posts.

Tips from the experts

Operators often talk about increasing the speed of communication to an unprecedented level, but in fact the speed of the Internet can be several times lower. A few years ago, gadgets at 3.6 Mbps were very popular. Now manufacturers produce devices designed to work at 14.4 or 28.8 Mbps.

But not the fact that the Internet speed in the user’s area will be decent. In this regard there is no point in overpaying for gadgets with high bandwidth. USB modems with speeds of 7.2 Mbit/s are enough, which is preferred by many users.

Almost all carriers sell devices from Huawei and ZTE. Also, different carriers may have the same model, but with different stickers. However, many gadgets are “tied” to a particular service provider. For example, if you bought a Beeline device, you can’t put a SIM card from MegaFon or MTS into it. Of course, there are ways to unlock the gadget, but that is the subject of a separate article. Also offer unlocked USB modems that can be inserted any SIM card. They are a little bit more expensive, but it is possible to change the provider.

Having figured out how to connect a modem to a laptop, the only thing left is to get online. And then you can wander freely through the world wide web.

ADSL modem

If you use Internet via ADSL-modem without Wi-Fi support it may be necessary to connect it to the router, which has this feature. As the reason for this may be a variety of factors, including a reluctance to buy an ADSL device with wireless network support. Connection of such equipment is possible with the help of special cable and adjustment of settings.

Note: After the setup it will be possible to connect to the Internet only via the router.

    Using a simple patch cord to the network card of the computer connect the Wi-Fi router. Use the “LAN” port on both PC and router.

connect, internet, computer, modem

    Just like in the case of Wi-Fi router, connect ADSL modem to PC with patch-cord.

Connect ADSL-modem and Wi-Fi router with additional patch-cord. In case of a router the cable must be connected to “WAN” port, while on the ADSL device any LAN-interface is used.

After completing the above procedure, both devices can be turned on. To get access to Internet you have to connect computer with router via cable or Wi-Fi.
