How to Use a Router to Receive Wi-Fi from Another Router: A Complete Guide

Do you want to extend your home's Wi-Fi coverage but don't know how to get your second router to receive the signal from your primary router? There are three ways to accomplish this: repeater mode, bridge (WDS) or client modeEach method has its own nuances, from connection speed to hardware compatibility.

Unlike purchasing a dedicated signal booster, using a second router is cheaper (or even free if you have an old device lying around). However, it's important to choose the right operating mode and configure the network settings, otherwise you risk unstable connection or loss of speedIn this article, we'll look at all connection methods, compare their pros and cons, and provide step-by-step instructions for popular router models, from budget ones TP-Link TL-WR840N to advanced ASUS RT-AX88U.

Before you begin setting up, please check two key points: 1) Make sure that both routers support the required mode (for example, not all older models work with WDS). 2) Write down the main network data: SSID (Wi-Fi name), password And channel (it can be seen in the settings of the main router).

1. Methods for connecting a router to another router's Wi-Fi: comparison of methods

The method you choose depends on your goals: whether you simply need to extend your coverage area or set up a separate network with internet access through your main router. Let's consider all the options:

If your goal is simply to boost Wi-Fi in the next room, choose repeater mode. To connect two networks with different names (for example, for guest access), this is suitable WDS. And if you need to connect a device that doesn’t have Wi-Fi (for example, a desktop PC) via cable, use client mode.

2. Configuring the router in repeater mode

This is the most popular method, as it doesn't require cables and works with most modern routers. The essence of the method: a second router connects to the main network via Wi-Fi and retransmits its signal, increasing coverage. However, connection speed will decrease by approximately 30–50% due to double data transfer.

The instructions are suitable for routers. TP-Link, ASUS, Keenetic, Mercusys and others with the function Repeater or Range ExtenderLet's look at the setup using an example. TP-Link Archer C6:

1. Connect the second router to the computer via cable (via port LAN) or via Wi-Fi (if it is already distributing the network).

2. Open the router's web interface by entering into your browser 192.168.0.1 or 192.168.1.1 (the address is indicated on the device sticker). The default login and password are usually admin/admin.

3. Go to the section Additional settings → Operating mode (or Operation Mode) and select Repeater (repeater).

4. Click Search (Survey), select the main network from the list (by name) SSID) and enter its password. Save the settings.

The primary network name (SSID) is correct|

The Wi-Fi password was entered correctly|

The main network channel is the same as the repeater channel|

The DHCP function is disabled on the second router (if there is such an option) -->

After rebooting, the second router will begin rebroadcasting the signal. Please note: if the primary network operates on a frequency 5 GHz, and the repeater only supports 2.4 GHz, the connection may be unstable. In this case, you will have to switch the main router to 2.4 GHz or use another connection method.

⚠️ Attention: Some routers (eg. Zyxel Keenetic) in repeater mode, ports are automatically disabled LANIf you need to connect devices via cable, use the mode WISP (if it is in the settings).

3. Connecting via a WDS Bridge: Step-by-Step Instructions

Mode WDS (Wireless Distribution System) Allows you to connect two routers via Wi-Fi without losing speed (unlike a repeater). Both devices can share the Internet under their own names (SSID), which is convenient for separating traffic. For example, one router provides internet for home devices, and the other for guest devices.

Important condition: Both routers must support WDSThis feature is available on most models. ASUS, TP-Link, D-Link, but may not be available on budget devices. Check the specifications for your model on the manufacturer's website.

Let's set up WDS using a router as an example ASUS RT-N18U:

1. Connect the second router to your computer via cable and log into its web interface.

2. Go to the section Administration → Operating Mode and select Access Point (AP) mode or WDS (depending on the firmware).

3. In the wireless network settings (Wireless) turn on WDS and press Search (Site Survey). Select the main network and enter its password.

4. Specify the same channel, as on the main router (for example, 6 or 11 For 2.4 GHz).

5. Turn it off DHCP server on the second router (to avoid IP address conflicts).

6. Save the settings and reboot your device.

Once configured, both routers will operate as a single network, but with different Wi-Fi names. Devices will be able to automatically switch between them (if the network names match) or connect manually to the desired one.

What to do if WDS is not working?

If routers do not communicate via WDS, check:

1) Do the security standards match (e.g. both use WPA2-PSK).

2) Is there any interference on the selected channel (try changing the channel on the main router).

3) Do both devices support the same band (2.4 GHz or 5 GHz).

If the problem persists, try updating your router's firmware or using repeater mode.

⚠️ Attention: In WDS mode, some routers block access to their settings via Wi-Fi. To access the second router's web interface, connect to it via cable.

4. Client mode: connecting devices to Wi-Fi via cable

This method is useful if you need to connect a device to the Internet that does not have Wi-Fi (for example, Smart TV, game console or desktop PC). The second router acts as client: it connects to the main network via Wi-Fi and then distributes the Internet through its ports LAN.

Not all routers support client mode. Among the supported models are: TP-Link TL-WR841N, ASUS RT-N12, MikroTik hAP liteIf your device does not have this feature, use the mode WISP (if any) or buy a specialized one Wi-Fi adapter.

Setting up an example TP-Link TL-WR841N:

1. Connect the router to your computer via cable and log in to the web interface.

2. Go to Network → LAN and change IP address router so that it doesn't conflict with the main network. For example, if the main router has an address 192.168.1.1, ask the second one 192.168.1.2.

3. In the section Wireless → Wireless Settings Set up a connection to the main network:

   • Please specify SSID main router.
   • Select mode Client.
   • Enter your password.

Turn it off DHCP on the second router (DHCP → DHCP Settings → Disable).

Connect a device (e.g. Smart TV) to the port LAN second router.

Now your device will receive the Internet via cable, and the second router will act as wired Wi-Fi adapterThis method minimizes speed losses because data is transmitted over a cable rather than relayed over the air.

5. Common mistakes and their solutions

Even with proper setup, problems can still arise. Here are the most common errors and how to fix them:

• 🔴 The router does not connect to the main network:

  Check if safety standards are met (e.g. WPA2-PSK on both devices). If the main router uses WPA3, and the second one does not support it, change the security settings on the main one.

• 🔴 Slow speed or dropped connections:

  Try changing the channel on your main router (for example, from 6 on 11). Use a Wi-Fi analyzer (for example, the app Wi-Fi Analyzer for Android) to find the least crowded channel.

• 🔴 Devices do not switch between routers:

  If both routers have the same network name (SSID), but the devices are stuck on one of them, turn on the function Roaming (if it is in the settings) or use different network names.

• 🔴 No access to the second router's settings:

  If you are connected via Wi-Fi, try using a cable. Also, check if there are any IP address conflicts (for example, both routers have 192.168.1.1).

If none of the methods helped, reset the second router to factory settings (Reset) and repeat the setup from scratch. Also, make sure both devices have the latest firmware version installed.

⚠️ Attention: Router interfaces may vary depending on the model and firmware version. If your device doesn't have the menu items mentioned above, please refer to the manufacturer's official manual.

6. How to choose the optimal location for routers

Even perfectly configured routers will perform poorly if they're placed in the wrong locations. Here are the key placement guidelines:

• 📡 Distance between routers: Optimally, 10–15 meters. If the routers are too far away, the signal will be weak; if they are too close, interference will occur.
• 🚪 Obstacles: Walls, furniture, and appliances (especially microwaves) weaken the signal. Try to place your routers so there are minimal obstructions between them.
• 📶 Height: It's best to place the router 1–2 meters above the floor (for example, on a shelf or table). Don't place it on the floor or in a closed cabinet.
• 🔄 Antenna direction: If the antennas are detachable, point them in different directions: one vertically, the other horizontally. This will improve coverage.

To check the signal quality, use applications like Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS). They will show the signal strength at different points in the room and help you choose the best location for the second router.

7. Alternative ways to boost Wi-Fi

If setting up a second router seems complicated or doesn't produce the desired results, consider alternative options:

• 📶 Mesh systems: Modern solutions like TP-Link Deco or Google Nest Wi-Fi Automatically configure the network and ensure seamless roaming between points. Ideal for large homes.
• 🔌 Powerline adapters: They transmit internet through electrical wiring. They are suitable if the routers are far apart but there is a common power grid (for example, TP-Link AV1000).
• 📡 Directional antennas: Signal boosters with external antennas (eg Alfa AWUS036ACH) will help if you need to "reach" a remote access point.
• 🔄 Router replacement: If the main router is old (for example, D-Link DIR-300), its performance may not be sufficient for stable operation with the extender. In this case, it's easier to buy a new router with support Wi-Fi 6.

Mesh systems are the simplest, but also the most expensive, solution. Powerline adapters are cheaper, but their speed depends on the quality of the wiring. Directional antennas require precise tuning but provide the greatest signal gain over long distances.

FAQ: Answers to Frequently Asked Questions

Is it possible to use a router in repeater mode if it doesn't have this feature in the settings?

Yes, but you will have to use alternative methods:

• Install third-party firmware (eg. DD-WRT or OpenWRT), if your model supports it. These firmware versions add repeater mode even to budget routers.
• Set up WDS, if your router has one. This mode is largely similar to the repeater mode, but requires support on both devices.
• Connect the second router to the main one via cable and configure it as an access point (AP). This won't boost Wi-Fi, but it will expand the number of ports. LAN.

Why does the Internet work after setting up WDS, but the local network between devices is not visible?

This is a known issue with WDS mode: some routers do not forward local traffic between connected devices. Solutions:

• Check your settings AP Isolation (client isolation) - it should be disabled.
• Use the same one IP pool on both routers (for example, 192.168.1.0/24).
• If the local network is critical, replace WDS with the mode client with cable laying between routers.

Which mode is best for a game console: repeater, WDS, or client?

For game consoles (PlayStation, Xbox) and the PC is optimal client mode, because:

• It minimizes delays (ping), since the data is transmitted via cable.
• Eliminates speed losses typical of a repeater.
• Provides a stable connection, which is critical for online gaming.

If cable routing is not possible, use WDS with the same SSID or buy Wi-Fi adapter with support 5 GHz (For example, ASUS USB-AC68).

Can 5GHz be used for communication between routers?

Yes, but with some reservations:

• Range 5 GHz Provides high speed, but has poorer penetration through walls. If the routers are in different rooms, the signal may be unstable.
• Not all routers support WDS or repeater in the range 5 GHzCheck the specifications for your model.
• For maximum stability, use 5 GHz for communication between routers, and leave it for client devices 2.4 GHz.

What should I do if, after setting up a second router, the main one stops providing internet?

Most likely it happened IP conflict or a failure DHCPFollow these steps:

1. Disconnect the second router from the network.
2. Reboot the main router (pull the power off for 30 seconds).
3. Check that it is disabled on the second router. DHCP server (if it works in repeater or client mode).
4. Make sure that the IP addresses of the routers do not match (for example, 192.168.1.1 And 192.168.1.2).

If the problem persists, reset the second router to factory settings and set it up again.
