How to Transfer Internet from One Router to Another via Wi-Fi: 3 Proven Methods

Want to extend Wi-Fi coverage in your home or office, but running a cable between your routers isn't an option? Wireless internet is the optimal solution if both devices support wireless technology. However, not all methods are equally effective: some experience speed loss, others encounter compatibility issues, and sometimes the connection drops every 10 minutes.

In this article we will analyze three working methods Internet transfer between routers via Wi-Fi: bridge mode (WDS), client connection And signal repeaterFor each method, we will provide step-by-step instructions taking into account the nuances of different manufacturers (TP-Link, ASUS, Keenetic, MikroTik), and we'll also point out which settings critically impact connection stability. Finally, we'll provide a comparison table of methods and answers to frequently asked questions.

Before you begin, check two key points: 1. Both routers must operate in the same range (2.4 GHz or 5 GHz), otherwise the connection will be impossible. 2. The main router (the one that distributes the Internet) should have MAC address filter disabled - otherwise the secondary router will not be able to connect.

1. Method: Bridge mode (WDS) - stable connection without IP loss

Technology WDS (Wireless Distribution System) Allows you to connect two routers into a single network while preserving the devices' original IP addresses. This means connected devices (smartphones, laptops) will be able to see each other on the local network—convenient for file transfers or LAN gaming.

However, WDS has limitations:

• 🔄 Both routers must support WDS (check the model specifications).
• 📶 Connection speed is reduced by approximately 30-50% due to double data transfer.
• 🔒 Not all routers support WPA3—you often have to switch to WPA2-PSK.

How to set up WDS using an example TP-Link:

1. Connect to secondary router (the one that will receive the Internet) via cable or Wi-Fi.
2. Go to Wireless Mode → WDS Settings.
3. Click Search and select the network main router.
4. In the field Encryption type Specify the same one as on the main router (for example, WPA2-PSK).
5. Enter the Wi-Fi password of the main router and save the settings.
6. Disable DHCP on the secondary router (Network → DHCP Server → Disable).

For ASUS the path will be different: Administration → Operation Mode → Repeater Mode, but the essence is the same - specify the SSID and password of the main network. On Keenetic WDS is configured via System Monitor → Segment → Add Access Point.

DHCP is disabled on the secondary router|The Wi-Fi channel on both routers is the same|The encryption type is the same|The routers' IP addresses do not conflict (for example, 192.168.1.1 and 192.168.1.2)

-->

⚠️ Attention: If the internet doesn't work after setting up WDS, check if the main router is blocking the connection by MAC address. On some models MikroTik You need to manually add the MAC address of the secondary router to the list of allowed devices (Wireless → Security Profiles).

2. Method: Client mode - when the secondary router works as an adapter

This method is suitable if you need to connect a device to the Internet that does not have Wi-Fi (for example, Smart TV, printer or game console). The secondary router acts as client, connecting to the main network and distributing the Internet via cable (LAN) or your Wi-Fi.

Advantages of client mode:

• 🔌 You can connect devices without Wi-Fi via cable.
• 📡 No speed loss, as in WDS (if you use a cable for end devices).
• 🔄 Supported by almost all routers, even older ones.

Flaws:

• 🚫 Devices from the primary and secondary networks will not see each other on the local network.
• 🔒 On some routers, you will have to disable DHCP manually.

Instructions for TP-Link:

1. Go to Wireless → Wireless Settings.
2. Turn on Enable WDS (yes, WDS is used here too, but in client mode).
3. Click Search, select the main router network and enter the password.
4. Go to Network → LAN and change the IP address of the secondary router (for example, from 192.168.1.1 on 192.168.1.2) to avoid conflict.
5. Disable DHCP (DHCP → DHCP Settings → Disable).
6. Connect a device (such as a TV) to the LAN port of the secondary router.

On ASUS The client mode is configured via Administration → Operating Mode → Media Bridge Mode. For Keenetic select System Monitor → Segment → Connect to another Wi-Fi network.

⚠️ Attention: If after setting up the device the IP address is not received, check if DHCP is enabled on the main thing router. Also, make sure the cable is connected to the port. LAN (not WAN!) of the secondary router - otherwise there will be no connection.

What should I do if my router doesn't support client mode?

If your router firmware does not have a client or media bridge mode, you can bypass the limitation using alternative firmware, for example DD-WRT or OpenWRTHowever, this requires experience and may void the warranty. For beginners, it's easier to buy an inexpensive router that supports client mode (for example, TP-Link TL-WR841N or ASUS RT-N12).

3. Method: Repeater mode - simple, but with speed losses

Mode repeater — the easiest to set up, but the least efficient in terms of speed. The secondary router connects to the main network and retransmits its signal, increasing coverage. However, each repeater reduces speed by approximately 50%, and if there are several, the network becomes practically unusable for video or gaming.

When to use Repeater:

• 🏠 Need to quickly expand the Wi-Fi range in a remote room (for example, at a summer house).
• 🔄 There is no option to configure WDS or client mode.
• 📱 You don't need high speed (enough for social networks and email).

How to set up a repeater TP-Link:

1. Go to Additional settings → Operating mode → Signal booster (Repeater).
2. Click Next and select the main router network from the list.
3. Enter your Wi-Fi password and save the settings.
4. Reboot your router.

For ASUS the path is this: Administration → Operation Mode → Repeater ModeOn . Keenetic select System Monitor → Segment → Signal Booster.

Once configured, the secondary router will broadcast the network with the same name (SSID), but with the addition of a suffix (for example, MyWiFi_EXT). This can cause confusion for devices that are constantly reconnecting between routers. To avoid this problem, Disable automatic Wi-Fi switching on smartphones and laptops.

Comparison of methods: which one to choose?

To make your decision easier, we've compiled the key characteristics of each method in a table:

Critical nuance: If your main router operates within the range 5 GHz, and the secondary one only supports 2.4 GHz, connection between them will be impossible. In this case, you'll either have to change the main router's settings or purchase compatible equipment.

Common mistakes and how to avoid them

Even with proper configuration, the connection between routers may be unstable. Here are the most common errors and their solutions:

• 🔌 Routers do not see each other:
  • Check that both devices are operating in the same band (2.4 GHz or 5 GHz).
  • Make sure the MAC address filter is disabled on the main router.
  • If used 5 GHz, reduce the distance between routers - this range penetrates walls worse.
• 🌐 No internet access:
  • Check if DHCP is enabled on the main thing router.
  • Make sure that the IP addresses of the routers do not conflict (for example, both should not be 192.168.1.1).
  • Reboot both routers (first the main one, then the secondary one).
• 📶 Weak signal or constant disconnections:
  • Change the Wi-Fi channel on the main router (for example, from Auto on 6 or 11).
  • Reduce the transmit power if the routers are too close (may cause interference).
  • Update the firmware on both routers.

⚠️ Attention: If you use routers from different manufacturers (for example, TP-Link And ASUS), there may be issues with security protocol compatibility. In this case, try installing on both devices. WPA2-PSK with encryption AES - this is the most universal option.

How to check the connection quality between routers

After setting up, it's important to ensure the connection is stable and the speed doesn't drop too much. Here's how:

1. Ping: Open Command Prompt (Win + R → cmd) and run the command:

   ping 192.168.1.1 -t

   (replace 192.168.1.1 to the IP of the main router).

   If the ping is consistently lower 50 ms and there's no packet loss—the connection is good. If your ping fluctuates or you're experiencing packet loss, check your channel settings or the distance between your routers.

2. Speed ​​test: Connect to the secondary router's network and run the test Speedtest.netCompare the result with the speed when connected directly to the main router. If the difference is greater than 50%, try a different connection method.
3. Checking the local network: If you used WDS, make sure devices from different networks can see each other. To do this, try pinging a device connected to the secondary router from a laptop connected to the main router:

   ping 192.168.1.100

   (replace 192.168.1.100 to the real IP of the device).

If the speed is too slow, try the following:

• 🔄 Switch both routers to the same channel 40 MHz (instead of 20 MHz or Auto).
• 📡 Set a fixed channel on the main router (for example, 6), and not Auto.
• 🔌 If possible, use a cable to connect devices to the secondary router (in client mode).

FAQ: Answers to Frequently Asked Questions

Is it possible to connect three routers in one Wi-Fi chain?

Technically yes, but it's highly discouraged. Each additional "hop" between routers reduces the speed by half. For example, if you have internet 100 Mbps, then after the second router there will be ~ left25 Mbps, and after the third - 10–15 MbpsIt is better to use a cable to connect at least one of the routers.

Why can't devices see each other on the local network after setting up WDS?

This is a typical issue with subnet mismatches. Make sure:

• The IP addresses of the routers are in the same subnet (for example, 192.168.1.1 And 192.168.1.2).
• DHCP is disabled on the secondary router.
• Client isolation is not enabled on the main router (AP Isolation).

If the problem persists, try manually registering the gateway on devices connected to the secondary router (the gateway should be the IP of the main router).

Which router is best for bridge mode?

For stable operation in WDS or client mode, choose routers with:

• Dual-band Wi-Fi (2.4 GHz + 5 GHz).
• Support 802.11ac (or newer).
• A powerful processor (for example, Broadcom BCM4708, Qualcomm IPQ4018).

Good options:

• ASUS RT-AC68U — reliable for WDS, supports AiMesh.
• TP-Link Archer C7 - budget, but stable in bridge mode.
• Keenetic Ultra — the best choice for complex networks (supports Mesh).

Avoid cheap models on Realtek or MediaTek - They often slow down in repeater mode.

Is it possible to use a Mesh system instead of a router-to-router connection?

Yes, Mesh systems (eg. TP-Link Deco, ASUS ZenWiFi, Google Nest WiFi) are specifically designed for seamless roaming between access points. They automatically select the best channel and do not require manual WDS configuration. However, mesh routers are more expensive than two separate routers.

If you already have two routers that support Mesh (for example, ASUS with AiMesh technology or Keenetic with the system Keenetic Mesh), you can combine them into a Mesh network without purchasing new equipment.

Why does the speed drop by 4 times after setting up a repeater?

This is a normal phenomenon for the regime. Repeater, since data is transmitted twice: first from the main router to the repeater, then from the repeater to the device. To reduce losses:

• Use range 5 GHz (if both routers support it).
• Place the repeater as close to the main router as possible.
• Disable all additional functions on the repeater (QoS, Parental Control).

If speed is critical, consider the option with client mode + cable to end devices.
