How to set up a modem in router mode. Router Wi-Fi mode - What are they and how to set them up? How to set up a modem in router mode

Facebook

Router ( router) - a network device that forwards data packets between different network segments and makes decisions based on information about the network topology and certain rules set by the administrator.
Why is this necessary? In this mode, the modem independently connects to the provider without your participation, and you gain access to the Internet. The example considers the connection type PPPoE (PPP over Ethernet), advanced configuration tools are not explained.

For owners of D-Link routers (and not only) there is a newer post about setting up in router mode and distributing wi-fi through your router.

1.DHCP
Windows users must go to the Network and Sharing Center, tab "Change adapter settings" - "Local Area Connection" - "Properties" - "Internet Protocol version 4 (IPv4)" - "Properties". If you don't know your IP address and DNS addresses, you probably get them automatically. In this case, check the “Obtain an IP address automatically” and “Obtain a DNS server address automatically” checkboxes.
Linux users They themselves know what to do, they must check the operation of dhcp and configure it.

2. Connection to modem
Windows: press the Win+R key combination, in the window that appears, enter cmd, then ping 192.168.1.1
Linux: ping 192.168.1.1
If everything is ok, move on

3. Setting up the modem
Open the browser and enter in the address bar: http://192.168.1.1/
In response, we receive an authorization window. Default login and password: admin. You can change your password later in Settings.
So, now we have the main menu. Select Wizard. Change the VPI and VCI settings as necessary. If you don't know what it is, don't touch it.

Select the WAN Connection Type and Encapsulation Mode. As mentioned above, our example uses PPPoE:

Enter your username and password, select the connection type:

The next menu is most useful to local network administrators, because... This is where you configure the DSL router's IP address, subnet mask, and DHCP. Regular users can leave the default values or do this:

Many users have an ADSL modem. But not everyone knows that this device can be not only an “adapter” between a computer and a telephone line. If the modem is equipped with a LAN port and is connected to the computer with an Ethernet cable, then most likely such a device can act as a router. We'll look at how to configure a modem as a router here.

Modem with LAN port

The ADSL modem can operate in one of the modes: “bridge” or “router”. The second option is good because you can connect not one computer, but many, to the modem (that is, to the router). True, you will have to use a switch for this. You can also directly connect a Wi-Fi access point to the router and get a wireless network.

Router and modem connection diagram

To connect an external IPTV set-top box, you need an additional LAN port (so you’ll still have to buy a switch). You can watch IP-TV through a computer, but to do this you will need to switch the modem to “router” mode (and then configure an additional connection interface in it). What has been said about IPTV is true for most ADSL providers, including Rostelecom.

Setting up the modem in router mode

How to log into the web interface?

The value of the IP address of the modem graphical interface must be indicated on the sticker or in the instructions. First we try to get into it without performing a factory reset.

Modem LAN connector - connect to the computer as shown:

Connection diagram of the modem to the PC

The network card in the computer is configured as follows:

IP address – any one belonging to the modem address range
Gateway address – equal to the modem’s IP address (or web interface address)
The network mask is set “with the last zero” (we give an example):

Setting up a network card

If, after checking several address values, it becomes clear that you cannot log in, here is the only advice: you need to reset the modem settings. A minute or later after turning on the modem’s power, press the reset button on the case (holding it for 10-15 seconds).

It is important to know that you can perform a reset only if you know the values of the VPI and VCI parameters for further connection configuration. Otherwise, you won’t be able to configure the modem even “as it was.”

After the reset, you can connect to any modem by configuring the network card to “auto” IP and DNS. The sequence is as follows: reset, configure the network card, reboot the PC.

Setting up a connection in the modem router

We look at how to configure a modem in router mode using the example of the D-Link DSL-2500U BRU device. When entering the interface, provide the administrator login and password (the word admin):

Main interface tab

You will need to remove the “extra” connection interfaces (using “Remove”), and click “Add”:

Setting up a new connection

Please note: if on the second page you specify the “Bridging” mode instead of “PPPoE”, you will get a modem operating in the “bridge” mode. The setup boils down to setting the connection parameters and then clicking “Next”.

PPPoE connection parameters:

VPI and VCI values for the Internet channel
Encapsulation mode (usually LLC)
Subscriber name and password
“Static” IP (only if used)

Check the “Keep Alive” checkbox if you want to get a connection that works all the time. The “NAT” and “Firewall” options must be enabled (and “IGMP” - only in the case of transmission by an IPTV provider, moreover, over one channel along with the Internet). “WAN Service” – should always be used. At the last stage, click “Apply” (and then “Finish”). Successful setup.

Additional features available in router mode

IPTV, VoIP option and others

The “router” mode is good because you can configure several interfaces for connecting to the provider (one, PPPoE, is an Internet channel). Rostelecom, for example, broadcasts IPTV via a separate channel. Also, additional interfaces are used to enable the VoIP option or some others:

Multiple connection interfaces

Please note that the VCI/VPI values for each interface are different. The second and subsequent connection channels can be configured in “bridge” mode. In some modems, you must additionally indicate that the main connection gateway is the PPPoE interface:

Setting up D-Link modems, “new” graphical interface

If there are several LAN ports, you also need to “bridge” the bridge interface with one of the ports. Study the instructions for the modem (if there is only one LAN port, you will not need to perform such settings).

Connection operating modes in the router

“Keep Alive” – always on (also known as “Always On”), this mode is recommended to be used
“Dial On Demand” – automatic connection when accessing Internet resources (disconnection occurs after a set time after the transfer is completed)
“Manual Connection” – connect/disconnect a connection through a tab (usually the main one) in the web interface

How to set up an Internet connection in a D-Link modem with a new graphical interface option - shown in the film (router mode, without IPTV):

I decided to write a short note with simple explanations on the topic, what is bridge mode (bridge) and router mode (router) in the ADSL modem. I won’t write here which mode is better or worse, and it’s clear that everything depends on the task you face. I’ll try to explain with my fingers how they differ, and you can decide which is better - bridge or router🙂 The names of the modes come from the English words bridge (bridge) and router (router). That is, the phrases that the modem operates in bridge mode or in router mode will also be true.

Now about the differences. ADSL modem, which works in bridge mode, is nothing more than just an adapter between the cord from your telephone jack and the power cord that connects to the computer's network card. Since it is impossible to directly connect a telephone wire to the network card, we need something to which we connect a telephone wire to the input, and at the output we get a standard network wire. This something is ADSL modem and bridge mode, it performs only this function - an adapter. It may not sound quite familiar, but in essence it is so. The modem cannot do anything in this mode. In order to initiate an Internet connection, you must be authorized by your provider and obtain network settings (external IP address). Since the modem is in bridge mode, it is just an adapter, this operation is carried out by the computer. That is, you set up a network connection with your provider on your computer, enter your username and password there, and connect to the Internet as needed.

Now it's in router mode. In this mode, the ADSL modem, along with performing the function of an adapter, is already a more intelligent network device. We can say that in this mode ADSL modem is a small computer, which provides some services for your personal computer. Now it is not your computer that performs authentication and obtaining network settings, but ADSL modem. To do this, you must first enter the necessary connection parameters, and of course the login and password that your provider gave you. The ADSL modem itself will contact the provider and establish a connection. Even if the computer is turned off, the modem will still be able to maintain a connection to the Internet. Thus, if you have modem with Wi-Fi access point, then through it you can access the Internet, for example, from a communicator or laptop, without turning on the main computer. When the modem is operating in router mode, it becomes active built-in modem firewall - firewall(firewall). In this mode, your computer is a little more protected from the outside world. Other functions also become available (depending on the modem), for example, built-in DHCP server.

Then you can simply speculate about the advantages of an ADSL modem in “bridge” mode and what are the advantages in “router” mode. For example, if you need an external IP address to be assigned specifically to the computer, then the modem must operate in bridge mode, and if you want to use the modem’s built-in firewall, then it (the modem) must be configured in router mode. If you have Wi-Fi devices (phones, communicators, laptops, etc.) and the modem has a Wi-Fi access point, then it must also be configured in router mode.

When using wireless Internet, difficulties may arise due to the fact that the router distributing it is too far from the receiving device. Connection problems can also occur due to walls, furniture or household appliances interfering with the Wi-Fi signal.

The best solution is to change the location of the router. But if this is not possible, you can use a second router to strengthen the signal. The technology used for this type of connection is called Wireless Bridge or WDS. Both devices must use the same data channel, encryption method, and Wi-Fi frequency.

To configure a wireless bridge on TP-Link, log into the web interface, the address of which is located on its bottom panel. The login and password for authorization can be specified there. The default username and password are admin. Enter these details and click the “Login” button.

Go to the “Wireless Mode -> Wireless Settings” section and check the box next to “Enable WDS”. This will add additional text fields that you can use to add network data. If you don't want to fill them in manually, click the Search button to display all available wireless networks.

Find the network you want to connect to, then click the “Connect” link in the last column of the table. A convenient feature is the display of channels on which active Wi-Fi is working. In the future, when setting up a wireless bridge, select the same channel as the main network.

The network data will be copied to the setup screen, all you have to do is enter the authorization information. Select the authentication type from the drop-down list. It must match the type installed on the main router you want to connect to. Then enter the password you usually use to connect to Wi-Fi.

In the "DHCP -> DHCP Settings" section, disable the dynamic IP address server. This is required to ensure that addressing conflicts do not arise when DHCP operates. After the setting takes effect, only the main router will be responsible for dynamic IP setting.

Important! WDS will only be activated after rebooting the receiving router. There is no need to reboot the main router

Connecting routers with a cable

If the routers are far from each other or there is too much interference in the Wi-Fi signal path, it is recommended to use a wired connection. To do this, connect one input of the network cable to any of the LAN ports of the main device. Insert the other end of the cable into the Internet port of the receiving router. On modern routers, connection setup for this type of connection is performed automatically. In this case, the wireless mode will continue to work on both devices. You can configure separate SSIDs and set your own encryption settings for each network.

Using this method, you can implement even a large home or office network. But if you want to provide access to users from other apartments in your building, legal difficulties may arise. As a rule, Internet providers prohibit the connection of additional computers and wireless equipment outside the address specified in the contract. At the same time, it is possible to establish the fact that neighbors are connected only by physically inspecting the premises.

Note! With an indirect connection, the Internet access speed on the end device will be lower than with a direct connection.

Fixing possible problems

If the router is used in repeater mode, difficulties may arise due to the fact that the devices do not find each other. First, make sure that the wireless network coverage area includes the location of the second router. To do this, use any device that has Wi-Fi access. While at the receiving router's location, try connecting to the network.

If the network is not found or the connection is unsuccessful, it is recommended to place the receiving router closer to the main one that distributes Wi-Fi. After this, you can repeat the configuration of the router as a repeater, expanding network coverage. Also check if the channels used are the same. On a TP-Link router, you can change the channel in the same menu in which the WDS connection is made.

Connecting a 3G/4G modem via a Wi-Fi router

Devices used to connect via 3G or 4G are often made in the form of USB modems. This allows you to access the Internet without using wires, but has several disadvantages. The most significant of them is the lack of simultaneous ability to use the Internet on several devices.

You can solve this problem by using a separate router equipped with a USB input. To connect a USB modem through a router, insert it into the USB input on the device that distributes Wi-Fi. Often the port is located on the back panel, next to the Internet and LAN inputs.

In the next step, configure the Internet. To activate work via a 3G/4G modem, you must select the appropriate connection type and enter the data provided by the operator. In TP-Link routers, setting up a connection via a third-party USB modem is done in the “Network -> 3G/4G” menu. For ASUS devices, it is recommended to use the Quick Setup Wizard. You can find out more about the menu items for configuring other routers in their instructions or on the manufacturer’s website.

Note! Tariff plans used by 3G and 4G operators are not unlimited in most cases. You can control traffic consumption using the statistics of the main router.

The question on the agenda is how to configure router mode? If you are planning to create a wireless network at home, then I recommend choosing a router for this purpose, and not an access point, modem, repeater or anything else. Why? Because this device is multifunctional and replaces all these things. In this article we will look at its main operating modes and see how they are configured using the example of a model from Asus.

First of all, you need to understand the concepts. In total, the router has four main modes:

Access point
Repeater or Amplifier
Client, Bridge or Adapter
Modem

Access Point

In access point mode, or as foreigners call it “Access Point,” the router works as a device that turns a cable signal into a wireless one. The main difference between a router in access point mode and another network device, which is actually called an “access point,” is that it not only distributes WiFi, that is, turns wired Internet into a radio signal, but also has functionality for distributing IP addresses and port forwarding, what is the main function of the router.

Modem mode (ADSL Modem)

In pure video, a modem is a device that is designed to work with providers that provide access to the World Wide Web via a telephone cable using ADSL technology. And for nothing else - the modem itself either works in router mode or simply cannot. But it is capable of not only receiving the Internet via a telephone cord, but also relaying it wirelessly and assigning IP to other clients.

Repeater

In general, a “repeater” is a wireless extender or signal repeater that extends it from the wifi distribution point to a certain distance to connect computers located in an area of uncertain reception to the Internet. If our favorite wifi router has a repeater mode, it means it can do the same thing - lengthen the wireless signal, thereby expanding the reception area. In addition, repeater mode is useful if you need to bypass some obstacle when creating a wireless bridge when there is no line of sight between two access points. Then we place it in line of sight from both points and transmit the signal through it.

Client, or Bridge (Client, WISP, WDS, Bridge)

A router in bridge mode has many names, but the essence comes down to one thing - it receives a wireless signal and transmits it via cable to the device connected to it. Bridge mode is convenient to use when you need something, that is, some device that does not have a built-in wireless module, for example, a TV or printer.

How to set up Asus router mode?

In different models, setting the router mode occurs differently. We will need to connect to some existing Wi-Fi, which is distributed by some other router, and distribute it in our apartment. I show the example of Asus RT-N10U B in the new firmware.

Go to the admin panel (http://192.168.1.1), the “Administration” item, the “Operation mode” tab (red) or immediately click on “Wireless router” at the very top of the settings page (green).

Currently, the “Wireless Router” mode is activated by default. You will find its settings in this article, and we will check the second one - repeater mode. And click the “Save” button.

A page will open that displays all wireless networks within the reception range of the router. We select from them the one to which we need to connect and enter the access key if it is password-protected.

Click connect. After connecting to a third-party router, you can make another interesting setting: either use the data to access the existing network that we are extending. Or you can set your own - then we connect to ours with one data (SSID and password), and to the second one, into which the Internet cable is directly inserted and whose signal we are extending, with others.

Then it’s a matter of technique - we wait until all these settings are applied and you disconnect from the network. After that, the new one that you just created will appear in the list of available wireless connections. We connect to it - and forward, across the expanses of the RuNet!

WiFi router in access point mode

The Asus access point mode is that it is connected by cable to another router or modem, which in turn is connected to the provider and already transmits the wifi signal. It is convenient to use if your Internet works via an ADSL modem, but the router itself does not have such a built-in feature. Or if your router is not equipped with a wireless module and cannot distribute a signal via Wi-Fi. I think there is no point in disassembling it, since everything is described in detail in the article about the modem in router mode, the link to which I have already given above.

Asus router in bridge or client mode

The client is the one who receives something. This mode is called that because in it the router works in the opposite direction - it does not broadcast a wireless signal from the connected cable, but, on the contrary, receives the Internet via wifi from another access point and distributes it to other devices using a cable. This operating procedure is only available on some models.

The most striking example of a device working in this vein is a wifi adapter. And among routers, the Asus EA-N66 has this ability.

This mode is called “Wireless network adapter” in this model.

This type also allows you to combine two autonomous networks using a wireless “bridge”. When creating such a connection, both routers must have this mode (Bridge). Or you can make sure that one device is activated as an “access point” that broadcasts the signal, and the other as a “client” that receives it and distributes it via cables to computers on its network. From the Asus line, of which I am a fan, the modern model RT-N13U is suitable for organizing such a bridge.

In this post, I have listed all the main modes of a WiFi router and listed their most common names. I describe in more detail about setting up each of them in separate articles on the blog. If you come across any others and you don’t know how they work, then write in the comments, we’ll figure it out together.

Not all users of network equipment are aware that a regular router, in addition to its main purpose, namely connecting various computer networks as a gateway, is capable of performing several additional and very useful functions. One of them is called WDS (Wireless Distribution System) or the so-called bridge mode. Let's find out together why a bridge is needed on a router and how to enable and configure it?

Let's say you need to increase the range of your wireless network and you have two routers. Then you can connect one router to the Internet, and the second to the Wi-Fi network of the first network device, that is, build a kind of bridge between networks from your equipment. And this is where WDS technology comes in handy. You no longer need to buy an additional access point with a signal repeater function.

Among the disadvantages of the bridge mode, a noticeable loss in data transmission speed in the area between the main and second routers should be highlighted. Let's try to configure WDS on TP-Link routers ourselves; on models from other manufacturers, our actions will be similar with minor differences in the names of terms and the interface.

Step 1: Setting up the main router

First of all, we will set up a router that will provide access to the global network through an Internet provider. To do this, we need to go to the router’s web client and make the necessary changes to the equipment configuration.

Step 2: Setting up a second router

We've sorted out the main router and are moving on to setting up the secondary one. We won’t encounter any particular difficulties here either. All you need is attention and a logical approach.

At the end of our story, pay attention to an important fact. In WDS mode, we create another network on the second router, with its own name and password. It gives us access to the Internet through the main router, but is not a clone of the first network. This is the main difference between WDS technology and repeater mode, that is, repeater. We wish you a stable and fast Internet connection!

Currently, for many Internet users, whose work, and even their whole lives, are closely related to online activities (bloggers, traders, freelancers, etc.), it is an urgent task to organize “uninterrupted” access to the network at a reasonable price Internet. The easiest way to achieve this is by organizing an additional backup connection to the network through another telecom operator.

The main type of home connection to the Internet provider network is now connected via an Ethernet cable. In this case, Internet access through a mobile operator (3G/4G) is most often considered as a backup connection. It is this type of reservation that I will talk about in this article.

To achieve this, you must have the following:

router with USB port;
3G/4G USB modem supported by the router;
Ethernet connection to the Internet provider network;
activated SIM card with the optimal tariff plan for Internet access.

In my case, Internet access is provided using a modern wireless router DIR-825AC/G1A manufactured by D-Link with the latest available firmware version (Firmware) 3.0.2 installed with the Anweb interface. The Huawei E1550 3G USB modem I have is listed in the list of modem models supported by the router on the manufacturer’s website.

After installing the SIM card into the USB modem and connecting it to the router’s USB port, after about 30 seconds the modem lit up with a blue light, indicating that the 3G connection with the mobile operator had been raised. At the same time, in the advanced settings of the router in the section “ USB modem" On the page " basic settings» you can see information about the installed modem.

Since the function " Automatic connection creation", then after connecting the USB modem and establishing a connection with the provider, the router itself created a " 3G-usb0» connection to interface « 3G" and made it the main one, specifying it as the default gateway.

To enable the function " WAN Redundancy" is necessary in the section " Setting up connections" On the page " WAN Redundancy» change the position of the switch « Turn on».

By default, the primary connection is " 3g_usb0", and as a backup connection " WAN».

We swap connections by selecting them from the corresponding drop-down lists. If necessary, we change other reservation parameters, the meaning of which is clear from the names: “ Test host (IP)», « Check interval (1-60 sec)», « Check timeout (1-10 sec.)», "Number of active connection checks (1-10)" And " Number of inactive connection checks (1-10)" Then press the button “ APPLY».

Since previously the default gateway was on a 3G connection, a warning window will appear in which you must agree by clicking the " OK».

If the default gateway does not automatically switch to the connection " WAN", then you need to install it manually.

To check the backup operation, disconnect the WAN port cable, and after a few seconds refresh the page, observing how the connection is broken " WAN" and the default gateway will change to connection " 3g_usb0».

After connecting the cable to the WAN port, you can see the opposite picture.

As a result, we conclude that the WAN redundancy function works successfully.
