Connecting a 3g modem to the router. Connecting the router to the modem

In urban environments, connecting to the Internet is easy. You just need to submit a connection request to your city provider (one of many). Within two or three days you will be connected and even offered some promotional conditions as a new subscriber. But what should users do who live, for example, in the private sector, in remote areas of the region? City providers usually cannot reach there, because they have to spend a lot of cable or expensive equipment, which either does not pay off at all or only for a very long time. So you can understand the providers.

Fortunately, there are other solutions. For example, you can use a USB modem to connect to the Internet over a third (3G) or even fourth (4G) generation network. However, in this case, this modem has to be connected to a laptop. But how to connect a USB modem to a router and make the Internet accessible to any Wi-Fi device? This option is actively practiced by users who cannot be reached by the city provider.

Let's figure out how to connect a USB modem to a router

Let us immediately note that any router is not suitable for solving this problem. You need a special model with a modem connection function, that is, a router with a USB port for a modem. Next, we will tell you in detail what needs to be done.

So, setting up a router for a USB modem looks like this:

1. Install the software from the disks that come with the router and USB modem.
2. Disable PIN code verification on the SIM card. It is necessary. If there is a check that the router simply cannot understand, there will be no Internet. You can disable this using a regular mobile phone. Just insert the SIM card into your phone and disable PIN code verification in the settings.
3. Plug the modem into the USB port on the router.
4. Connect to the router from your laptop and go to the control panel. To do this, write the address in the address bar of your browser and you will be taken to the desired location. You can view the desired address on the device panel itself. In addition, it is also always indicated on the information sticker and in the instructions.
5. In the router menu, look for the buttons “Connection”, “Internet”, “Enable modem connection”. These buttons may be slightly different, but the gist should be something like this. We are interested in the modem connection function. It needs to be turned on.
6. After turning on, reboot the router. You can do this by clicking the reboot button in the menu bar. The router itself can also be physically rebooted: remove the plug from the socket and plug it back in.

Now you know how to connect a USB modem to your router. Usually this process is carried out simply, and no difficulties arise, but they still cannot be excluded. For example, the modem must first be configured on the computer. An unconfigured modem will not work with the router.

Advantages of this method

A router with a USB port for a modem is a good and practical solution that has its pros and cons. So, the advantages include the relative ease of connection. That is, you need to run no cables, drill holes, etc. Just connect the USB modem through the router and you're done. True, this is where the advantages end.

Minuses

The main disadvantage of such a connection is the high cost of the equipment and tariff. At a minimum, a router for a USB modem will cost more than a standard Wi-Fi router without a USB port. You also need to buy the modem itself separately, which can cost even more than the router itself. Depending on the operator you choose, the cost of the tariff may also be more or less high. But in any case, the subscription tariff will cost more than the one offered by the city provider.

Connection speed

If a city network requires an Internet connection at a speed of up to 100 Mbit per second, then a modem will definitely not be able to offer such speeds. Even if it uses a fourth generation (4G) data network, the actual speed will be around 15-20 Mbps, which, admittedly, is pretty cool. But, most likely, the modem will use some kind of third generation network technology (3G), and if the actual (and not advertised) speed is at least 5 Mbit per second, then this is already good. At a minimum, you will be able to watch movies online at this speed. Therefore, before connecting a USB modem to the router, make sure the Internet speed is real.

Is there another way out?

Some users often wonder if it is possible to connect a router to a USB modem without a USB port. Of course, this can be done, but it is extremely difficult. The idea is to open the router itself, solder a USB interface there and flash it with special firmware that will “see” the USB port. But few people practice such a scheme. However, there is another interesting way.

Distributing Wi-Fi from a laptop

If you have a modem, but do not have a router with a USB port for the modem, then you can connect to the Internet and create a Wi-Fi network at home using a regular laptop. It’s just that the laptop itself will replace our router. The main thing is that the laptop has a working Wi-Fi adapter.

The easiest way involves using the Connectify program. By the way, it is available on the Internet for free, but it also has a paid version with wider functionality. Free will suit us. Download it, install it on your computer and run it.

There we need to fill in the lines:

1. Hotspot Name is the name of your network. In the free version it will be standard and cannot be changed.
2. Password line - here enter the password that will be used to access the network.
3. Internet to share line. There you need to select from the drop-down list the source of the Internet signal that will be used for distribution via Wi-Fi. Select our modem:
4. In Share Over, select Wi-Fi.
5. In Sharing Mode, select WPA2 encryption.

Now click on the big button below - Start HotSpot. So we turned our laptop into an access point. Now it will distribute Wi-Fi instead of a regular router.

If you cannot configure this program for any reason, you can use others. For example, the free MyPublicWiFi program offers the same functionality. In addition to it, there is a program called myHotSpot with similar capabilities. You don't have to use any programs at all. The built-in tools of the Windows 7 operating system allow you to turn your laptop into an access point, but you will have to tinker with them. It is best to use third-party programs.

That's all. Now you know how to connect a USB modem to a router and distribute Wi-Fi from a laptop without a router at all.

Before connecting an adsl modem to a wifi router, you should make sure that the modem is configured correctly and is capable of providing a stable Internet connection.

In addition, you will need a twisted pair crossover cable. Such a cord is included in the delivery of most.

It is short in length and terminated at both ends with an RJ-45 plug, reminiscent of a telephone connector.

If you don't have a cable, you can easily purchase it at a computer store. Experts often call this cord a “patch cord.” To ensure noise immunity (which contributes), you should choose a cable of as short a length as possible (0.5-1 m). The price of a patch cord is 100-200 rubles.

So, to connect a wifi router via a Rostelecom adsl modem, you will need an ADSL modem, a Wi-Fi router and a connecting patch cord.

Setting up a classic adsl modem/wifi router from Rostelecom is described in detail in articles and.

If you have any difficulties setting up an adsl modem, you can always ask us a question in the comments to this article or using a special service.

How to connect an adsl modem to a wifi router?

Here we will dwell in detail on how to connect a wifi router via an adsl modem.

1. 1. Connect either end of the cord to the ADSL modem connector marked “LAN”. If there are several such connectors (LAN1, LAN2, ...), then you can use any of them. On some models, this port is designated “Ethernet” - this is an alternative name for the connector for the RJ-45 connector;
2. 2. Place the other plug of the patch cord into the “WAN” socket of the Wi-Fi router (which can also be designated “Internet”);
3. 3. Connect the Internet cable from your provider to the “DSL” connector of your modem. The following designations are also found: “ADSL”, “Line”. The standard ADSL modem connection diagram is shown in the figure:
   
   
4. 4. Make sure both devices are connected to power and turned on.

How to set up a wifi router via an adsl modem?

To configure a Wi-Fi router to connect to an ADSL modem:

You may also need to specify the provider's address and configure the router's MAC address. If you need to configure these parameters, please check with your provider's support service.

1. 4. Save the router settings - if the data is entered correctly, the adsl modem/wifi router Rostelecom combination should work properly. Read about the correct configuration of local network parameters on a desktop computer in articles and, and the intricacies of connecting mobile devices to WiFi are discussed in articles and.

Connecting a wifi router via a Rostelecom adsl modem: possible problems

If an error occurs when connecting an adsl modem to a wifi router, first of all you need to check the following points:

When it is not possible to connect to wired Internet, 3G modems come to the rescue; you can connect to the Internet almost anywhere. If the modem does not work as a wireless router, you can connect it to a Wi-Fi router, using the network on several devices at once. Today, of course, there are 4G routers, but they are, frankly speaking, not cheap.

To use gadgets in conjunction, the router must have a USB connector, which can be used not only for hard drives, flash drives or printers, but also for transferring data from modems. Not all routers support connecting modems; before purchasing them, you should check compatibility on the official websites of the manufacturers. Here are some router models that support Internet distribution from modems:

1. Asus RT-N18U, RT-AC56U, RT-N14U, RT-N66U, RT-N10U B;
2. Tp-Link TL-MR3420, TL-MR3220;
3. D-Link DSL-2650U, 2750U;
4. Zyxel Keenetic DSL, Keenetic Omni II, Zyxel Keenetic Viva, Zyxel Keenetic Extra.

Not all 3G USB modems are supported, but D-Link is guaranteed to work with Huawei: E150, E1550, E160G, E169G, E220, ZTE: MF112, MF626, MF627. Compatibility of other devices can be found on the manufacturers’ websites: Asus, Tp-Link, Zyxel.

Setting up the router

For the setup example, we will use a combination of TP-Link TL-MR3220 and Huawei E1550 3G modem. Before connecting, you need to check that the SIM card is not blocked by a PIN code. Next, we connect the modem to the router and open the latter’s Web interface. Its address is written on a sticker on the bottom of the router along with the username and password for logging in. Usually this is 192.168.0.1 or 192.168.1.1 and the login is admin, password is admin. Go to the Quick Setup tab:

After this, select the 3G only connection, since only the modem will be used. You can configure it as a backup, which is triggered when the main broadband is turned off, but we will not consider this possibility now.

Here we check the box next to Set the Dial Number, APN, Username and Password manuall, select Authentication Type: Chap and enter the data of the Dial Number, APN, login/password operator that is used in the modem.

For Intertelecom it is:

1. Dial number: #777
2. APN: it.od.ua;
3. Username and password: IT.

For Peoplenet:

1. Dial number: #777;
2. APN: #777;
3. This e-mail address is being protected from spambots. You need JavaScript enabled to view it. - number from the contract;
4. Password: 6 characters from the contract.

After waiting, the modem will connect to the network. To set up a Wi-Fi connection, click “Next”.

We assign a name to the access point, an encryption type and assign a password of at least 8 characters. We confirm the data entry and reboot the router with the “Reboot” button in the next menu. We wait for the reboot, make sure that the modem is working correctly, seeing the inscription Identify successful in the Network - 3G menu.

To automatically connect to the network, select Connect Automatically. After all the manipulations, you can try connecting your mobile devices via Wi-Fi and enjoy the Internet.

As you know, when connecting to the Internet using ADSL technology, the information between the subscriber and the provider has an analog signal. To convert it into a digital one, understandable for an Ethernet network and a computer, you need a converter called a modem (short for modulator-demodulator).

But not many modems have a routing function, that is, to connect several computers, and an additional router is required to distribute the Internet between several subscribers. In this article we will look at how to connect a modem through a router and how to configure it correctly.

ADSL Modem

So, when concluding the contract, the provider gave a modem as a bonus. Of course, not an expensive one, which is equipped with only two ports - one to the telephone line (DSL), the second to the computer’s network card (LAN).

The modem receives an analog signal coming from the provider to the DSL port, digitizes it, and outputs it to the LAN port. So that you can also use a simple telephone, the modem comes with a network filter splitter, which separates voice waves from the Internet and sends them to the appropriate channel.

Splitter

If you do not use a splitter, then due to the mixing of the computer signal and the telephone conversation, crackling and interference will be heard in the handset, and the Internet will crash.

Connecting to a router

If from the modem side everything is clear what to connect where, and the ports should not be confused (DSL is smaller than LAN), then from the router side, without the appropriate knowledge, everything is unclear, since the router has several ports that have the same connector, but different in functionality.

Router ports

As you can see from the picture, the router has five ports, and they are all physically the same. But four ports are orange and one is blue. This is the whole point - the orange ones are LAN ports to which local network computers are connected, and the blue one is the WAN port that faces the outside world. Although our modem also has an orange port, and it is called LAN, it must be connected to the blue WAN port of the router.

Connecting the router to the modem

That is, it turns out that for the modem it already transmits the Internet to the local network (LAN port), and for the router the modem is the outside world, therefore the blue port (WAN).

Having figured out how to connect the router to the modem using a patch court network cable, let’s move on to setting up the equipment.

Setting up devices

Before setting up, you need to prepare:

1. Turn off your router and modem;
2. Connect a network cable to their ports (LAN modem with WAN router);
3. Connect the telephone wire to the modem (DSL port, via splitter);
4. Connect the computer’s network card to any of the router’s LAN ports using a network patch cord;
5. Turn on the router (you don’t need to turn on the modem).

Entering the settings menu

Open any web browser on your computer and go to the router’s web page. The IP address of the router can be found either in the instructions or on the label under the bottom.

User authentication

Press “Enter” and go to the router settings menu.

Setting up a WAN port

A window will open, select the “Network” item, then the “WAN” sub-item.

Selecting WAN port settings

In the global port settings window, in the “Connection type” field, select the type most commonly used by ADSL providers, “PPPoE”.

Setting up a WAN port

Next, open the agreement and find the login and password for logging into the Internet. Enter them in the appropriate fields “User Name” and “Password”. If desired, put a checkmark next to the “Wan Connection Mode” field, thereby indicating that the connection must be established automatically.

Summary of WAN settings

Click the “Save” button so that all our settings are saved and working.

Internet access

Having configured the WAN port of the router, let's try to access the Internet. Turn off the router for a couple of minutes to be sure. Next, turn on the ADSL modem, look at the lights on the front panel so that the DSL and Internet indicators light up.

Modem front panel indicators

The DSL diode signals that a connection has been established with the provider, the Internet diode indicates that there is access to the Internet.

We launch the browser and go to any active website.

Possible problems

If all the indicators on both devices are on, but there is no Internet access, then check the following:

• Try pinging both the router and the router. Each of their devices has its own IP address;
• If both devices respond, then try changing the IP addresses of both devices. For example, assign 192.168.1.1 to the modem, and 192.168.0.1 to the router.
• Make sure that the ADSL port of the modem is definitely intended for the Internet and not IPTV. If the modem is equipped with both ports, then make sure that the network cable from the router is connected to the Internet port.

For clarity, a little video:

In this article we will look at an example of connecting to the Internet via a wifi router. The example is not standard, since the combination will consist of a simple adsl modem and a wifi router.

The non-standard nature of this approach is that in this case there are two devices on the table (an adsl modem and a wifi router), respectively, two sockets will be occupied in the surge protector and the number of wires will be twice as large. Let's not forget about the complexity of setup - you will have to configure two devices so that they can “get along” with each other.

This method of connecting to the Internet becomes an incomprehensible task for the average user, who barely understands how to connect these devices together physically, and at the network level it is a complete disaster.

Why do you need a combination of “adsl modem and wifi router”?

The point is that when connecting to broadband ADSL Internet You definitely need a modem that can receive and send a signal through a telephone line. There are such modems:

• Regular single- and multi-port (without WiFi module). Such modems can “distribute” the Internet only through the wires that connect to the computer.
• WiFi modems single- and multi-port(I also call them “Access Point”). You can connect to these modems both wired and wirelessly using WiFi wireless data transfer technology.

On a note! Wi-Fi is a trademark of the Wi-Fi Alliance for wireless networks based on the IEEE 802.11 standard

The term “Wi-Fi” was originally coined as a play on words to attract the consumer’s attention with a “hint” of Hi-Fi (High Fidelity, high accuracy). Despite the fact that at first the phrase “Wireless Fidelity” appeared in some WECA press releases, this wording has now been abandoned, and the term “Wi-Fi” is not deciphered in any way. (wikipedia.com)

The most suitable option when connecting broadband ADSL Internet via WiFi it would be to use a regular ADSL modem with a built-in wireless WiFi module, i.e. two devices in one. Fewer wires, fewer hassles to set up.

But what to do if the Internet is not broadband at all and it is connected not through a telephone line, but a dedicated one (VPN), i.e. Is the Internet “distributed” over the local network?

Indeed, in this case, the modem is completely superfluous, since a network cable is “thrown” to your computer and configured VPN connection.

On a note! VPN (English: Virtual Private Network) is a generalized name for technologies that allow one or more network connections (logical network) to be provided over another network (for example, the Internet). (wikipedia.com)

To organize wireless Internet via a dedicated line, you need a WiFi router (router). We simply connect the network cable to the desired socket on the router, set the correct settings, and access to the network becomes much more convenient due to the absence of a “beard” of wires.

The versatility of a WiFi router

The versatility of this device lies in the fact that when connected to broadband Internet(ADSL) via a regular wired modem, you can also configure wireless data transfer. All you need to do is plug the modem into your WiFi router and set the correct settings. Those. you can connect to broadband Internet so and to VPN.

Connecting a WiFi router and ADSL modem

You can “make friends” of these two devices with each other in several ways (simple and zigzag).

From my own experience I know that a simple method often does not give results, due to various reasons (old device firmware, etc.), you have to look for a solution to the problem in another, more non-standard way.

As an example, consider a wireless Internet connection via a “bundled” modem D link DSL-2500U And WiFi router D link DIR-320. This example is universal and fits most other similar models.

Let's start in order...

1. We check the local network connection. Open menu Start, in the search field, enter “View network connections” (this is the easiest way to open a window with network connections) in the list, click on the link View network connections.

In the Network Connections window, select LAN connection and call the context menu, click on the link in it Properties. In the Local Area Connection Properties window, select the component and press the button Properties. In the Internet Protocol Version 4 (TCP/IPv4) window, in the General tab, make sure that the parameters are set Obtain an IP address automatically And Obtain DNS server address automatically. Click on the OK button.

Local Area Connection - Properties

3. Once the modem is configured (the Internet indicator turns green), you can proceed to connecting it to the WiFi router and further settings.

Disconnect your modem and connect your WiFi router instead.

We insert one end of the network cable into the computer’s network card, and the other into the LAN connector on the router. As a rule, there are several of them, you can connect them to any one.

Open the browser and enter the URL in the address field (in my case, http://192.168.0.1) to access the router via the web interface. It is usually given in the documentation for the device or on its back side.

4. If the Username and Password are entered correctly, you will be taken to a new window and taken to the page .

5. First, let's configure the router for wireless data transfer via WiFi. In the menu on the left, select masonry Wireless Setup. In the window we are asked to choose manual or automatic setup mode. We will configure it manually, so click on the button Manual Wireless Connection Setup.

6. In the next window you need to configure the appropriate settings for the wireless network. At the top of the page there is a section WiFi Protection Setup, where you can configure the connection of clients that support the WPS (Wireless Protected Connection) function.

You can enable this option or not. I leave it turned off.

In chapter Wireless Network Gettings set the parameters:

• Enable Wireless– enable this option. The router will be able to receive and transmit signals wirelessly.
• Wireless Network Name - enter the name of your network in English (SSID) in the field, it will be used to identify the network.
• Enable Auto Channel Selection– we leave this parameter unchanged. It allows the router to independently select the communication channel for the wireless network.
• Wireless Channel– in this field you can manually specify the channel number for data transmission. In our case, we leave it unchanged.
• Transmission Rate— sets the data transfer speed over the WiFi wireless network. Leave the default value – Best.
• WMM Enable and Hidden Wireless– leave it as default.

In chapter Secure Mode choose WPA/WPA2 Wireless Security, which will allow us to protect our wireless network from unauthorized connections of neighbors and those within the network’s coverage radius.

• Cipher Tip - TKIP
• PSK/EAP – PSK
• Network Key – set the key yourself. It's arbitrary. Be sure to write it down, for example, in a text document; you will need it when connecting to a WiFi network. Any person to whom you tell this key will be able to connect to your network if they are within its range.

After filling out all the fields, click on the button Save Settings. This completes the setup of the router’s wireless network. The settings are saved in the device.

7. Now you need to view information about the device and write some parameters to a file. We will need them to configure the modem. Click on the button Status in the top menu of the web interface.

In the window copy data from the section Lan(MAC Addresses, IP Address and Mask) and save them in a text file.

But there is a possibility that when writing these parameters to the ADSL modem, the IP address range 192.168.0.x is occupied and it will not be possible to enter our router address (192.168.0.1). So let's change it in advance.

Click on the button Setup and in the window In chapter Router Settings change the field value Router IP Address from 192.168.0.1 to another, for example, 192.168.1.25. Click on the button Save Settings to save new settings.

We log into the router’s web control panel at the new address. In the browser window, enter http://192.168.1.25 in the address field, specify the default login and password.

The router control panel opens again.

8. Let's change the password to a more complex one. After all, you wouldn’t want someone to be able to remotely access your router and snoop on your wireless network password. To do this, click on the button Maintenance and in the section The login can be left the same, but the password can be changed by first writing it down somewhere, for example, in the same file.

After the password has been changed, click on the button Save Settings to save settings.

We log into the control panel again with a new password.

Now there is one step left until the final setup. But before that, let's summarize what has been done:

• Checked the network connection parameters - selected automatic mode
• Connected the ADSL modem and configured it to access the Internet
• Disconnected the modem, connected the WiFi router
• Configured the wireless network and the necessary security settings
• Changed the device's IP address (from 192.168.0.1 to 192.168.1.25)
• Changed the password from default to new.

Let's move on to the final part.

9. Log in to the router’s web control panel and select the tab Internet Setup in the menu on the left. In the window We are offered two options for setting up the Internet:

• Internet Connection Setup Wizard– Configuration using a wizard;
• – Manual setup.

Click on the button Manual Internet Connection Setup and in the next window in the section ACCESS POIN MODE put a tick opposite . We switched the WiFi router to access point mode, in which it can distribute the Internet to clients.

Click on the button Save Settings. The settings will be saved, and the router will go into mode Access Point Mode. The router is configured. Disconnect it from the computer.

11. Open the LAN tab in the menu on the left, and in the window press the button Add Entries .

12. In the window we ask MAC address WiFi router and its IP address. We previously saved these parameters to a file. Just copy and paste them into the required fields. Click on the button Save/Apply.

In the window a new entry will appear in the table with a static IP address and a unique MAC address of our router. Click on the button Save/Reboot. The modem will “go into reboot”.

13. After saving the settings, disconnect the modem from the computer and turn it off for a couple of minutes to end the connection session.

15. We connect the modem to the router using a second network cable. We insert one end into the modem, the other into the WAN (Internet) port on the router.

Connection and setup is complete. If everything was done correctly, the Internet will be broadcast via LAN and WiFi.

In this mode, the router distributes the Internet via LAN if several computers are connected to it via WiFi.

Wireless connection to a router (WiFi)

To connect to WiFi, you need to in the window Available connections select the network name (SSID) that we specified when setting up wireless data transfer. Since we have created a secure connection, we will need to enter access key, which we also created earlier.

Enter it in the required field and click OK. It will be saved and you will not need to enter it again.

To summarize, we can note that such an implementation is not standard, as we use Access Point mode in it, which means that the router will not create its own internal subnet, which, in principle, will not prevent us from accessing the Internet.

This mode helps in cases where it is impossible to connect to the Internet in a standard way, for example through DHCP mode (automatically obtaining an IP address from our provider).

If you are connected (or are going to connect) to broadband Internet, then it makes sense to use a more compact implementation in the form of an ADSL modem with a wireless WiFi module.

If you are connected to the Internet via a VPN (local area network), then you will have to use a WiFi router for a wireless connection. In this case, a modem is not needed. The router setup will differ from the example given.

But if it turns out that you have to set up wireless Internet using an adsl modem and WiFi router, this article will help you.
