How to connect a second router to the first via Wi-Fi: 3 working methods + step-by-step instructions

Extending Wi-Fi coverage in your home or office is a challenge many users face. One of the most effective ways to accomplish this is connect the second router to the first via Wi-Fi, without laying cables. This approach eliminates unnecessary wiring, maintains device mobility, and evenly distributes the network load. However, not everyone knows that there are several methods for this, each with its own nuances.

In this article we will look at Three main ways to connect routers wirelessly: mode WDS (wireless distributed system), setup bridge and using the function repeater. You will find out which option is best to choose for your model (TP-Link, ASUS, Keenetic, Zyxel and others), how to avoid common mistakes and achieve maximum data transfer speeds. And also, why it's sometimes better to run a cable, even if it seems inconvenient.

Before moving on to the settings, it is important to understand the key difference between the methods: WDS mode creates a single network with one name (SSID) and automatic roaming, while the bridge and repeater can duplicate or create a separate networkThis affects how devices connect and switch between access points.

1. Preparation: What you need to know before connecting

Before connecting two routers via Wi-Fi, check a few critical points:

• 🔄 Wi-Fi Standards CompatibilityIf the main router only works 802.11n (Wi-Fi 4), and the second one supports 802.11ac (Wi-Fi 5), the speed will be limited by the slower standard. Optimally, both devices support Wi-Fi 5 or Wi-Fi 6.
• 📶 Frequency rangeIt is better to use for connecting routers 5 GHz — there's less interference and higher speed. However, if the second router is far away, 2.4 GHz will provide better range (but lower speed).
• 🔒 Encryption typeBoth routers must support the same security protocol (WPA2-PSK or WPA3). If the main one is WPA3, and on the second only WPA2, you will have to lower the level of protection.
• 📡 Signal strengthIf the second router is located in an area with poor coverage from the first, the connection will be unstable. Check the signal strength using apps like Wi-Fi Analyzer (Android) or NetSpot (macOS/Windows).

Also note that when connecting wirelessly Internet speed will decrease by at least 30–50% due to double data transfer (first router → second router → device). If maximum speed is critical to you (for example, for 4K streaming or online gaming), consider the option with wired connection (LAN-to-LAN).

⚠️ Attention: Some budget router models (for example, TP-Link TL-WR740N or D-Link DIR-300) do not support WDS or Bridge mode. Before purchasing a second device, check its specifications on the manufacturer's official website.

2. Method 1: Connecting via WDS (single network)

Mode WDS (Wireless Distribution System) allows you to create a single Wi-Fi network with one name (SSID) and automatic switching between routers. This is convenient if you want devices (smartphones, laptops) to automatically select the access point with the best signal.

However, WDS has limitations:

• ⚡ Both routers must support WDS (budget models may not have this feature).
• 🔄 The connection speed is halved as data is transferred "in a chain".
• 🔒 Not all routers allow you to use WPA2/WPA3 in WDS mode - sometimes you have to switch to a less secure one WEP.

Instructions for routers TP-Link (for example Archer C6):

1. Connect the second router to the computer via cable (LAN port).
2. Go to the web interface at 192.168.0.1 or 192.168.1.1 (check the instructions).
3. Go to Wireless Mode → WDS Settings.
4. Click Search and select the main router network.
5. Enter the password for the main network and save the settings.
6. In the section DHCP Disable the server (so that only the main router distributes IP addresses).
7. Restart both devices.

For ASUS (For example, RT-AX55):

1. Go to Administration → Operating Mode and select Access Point (AP) mode.
2. IN Wireless Network → Bridge please indicate SSID main router and password.
3. Disable DHCP server in Local Network → DHCP Server.

Make sure both routers support WDS|

⚠️ Attention: If after setting up WDS devices do not connect to the network, check that the mode is enabled on the main router. WDS/Bridge (Sometimes it needs to be activated manually). Also, make sure that the Wi-Fi channels on both routers match (for example, Channel 6 on 2.4 GHz).

3. Method 2: Bridge mode - an alternative to WDS

If your routers do not support WDS, you can use the mode bridgeUnlike WDS, the second router connects to the first as a client and then distributes internet via cable or Wi-Fi. This method is more versatile, but requires manual configuration.

Advantages of Bridge mode:

• 🔧 Works on most modern routers (including Keenetic, Zyxel, MikroTik).
• 📶 Allows you to use different SSID for the main and second router (useful if you need to separate networks).
• 🔒 Supports WPA2/WPA3 without restrictions.

Flaws:

• ⚠️ No automatic roaming - devices will not automatically switch between networks.
• 🔌 If the second router distributes Wi-Fi, the speed will be lower than with a wired connection.

Instructions for Keenetic (for example Keenetic Hero):

1. Go to the web interface at my.keenetic.net.
2. Go to Home Network → Segments and create a new segment of the type Pavement.
3. IN Wireless network select Access point (AP) and specify the settings of the main router.
4. Disable DHCP in Home Network → IP Settings.

For Zyxel Keenetic (old models):

Interface → Wireless Network → Client
Specify the main router's SSID and password
Save and reload

4. Method 3: Using a Repeater

Mode repeater — the easiest way to extend Wi-Fi coverage. The second router in this case acts as a signal booster, repeating the network of the main router. The main advantage is no need to configure IP addresses or DHCP.

However, there are also disadvantages:

• 📉 The speed drops by 2 times (sometimes more), since the repeater receives and immediately retransmits the signal.
• 🔄 No roaming - devices do not switch automatically.
• 🔌 Not all routers support this mode (for example, Keenetic requires special firmware).

Instructions for TP-Link (for example TL-WA850RE):

1. Plug the extender into an outlet near your main router.
2. Connect to the repeater network (usually TP-Link_Extender_XXX).
3. Go to the web interface at 192.168.0.254.
4. Select the main router network and enter the password.
5. Move the repeater to the desired location (where the signal from the main router is still stable).

For ASUS (mode Repeater):

1. Go to Administration → Operating Mode.
2. Select Repeater mode.
3. Please specify SSID main router and save the settings.

What is the difference between Repeater and Bridge?

In mode Repeater The second router simply repeats the signal from the main one without changing the network settings. In the mode Bridge It connects as a client and can then distribute the Internet via its Wi-Fi or cable with different parameters (for example, a different SSID or password).

⚠️ Attention: If you are using a repeater in a network with Wi-Fi 6, make sure it supports this standard. Otherwise, the speed will drop to Wi-Fi 5 even for devices connected to the main router.

5. Connection optimization: how to increase speed and stability

After setting up the connection between the routers, test the network speed and stability. If the results are unsatisfactory, try these tips:

• 📡 Choose the right channelUse apps like Wi-Fi Analyzerto find the least crowded channel on 2.4 GHz or 5 GHzConfigure both routers to the same channel (in WDS mode) or different ones (in Bridge/Repeater mode).
• 🔄 Update the firmwareOutdated software versions may contain bugs that affect speed. Check for updates in the section System → Firmware Update.
• 📶 Place your routers optimallyThe second router must be located within the range of the main router’s reliable reception (at least 70% of the signal). Avoid obstacles (walls, furniture) and sources of interference (microwaves, cordless phones).
• 🔒 Use modern encryptionIf your router supports WPA3, turn it on. Not only is it safer, but it might also increase speed a little.
• 🔌 Disable unnecessary featuresOn the second router, deactivate QoS, IPv6 (if not used) and Guest network - this will reduce the load.

If the speed is still low, try change channel width:

• On 2.4 GHz install 20 MHz (more stability, less speed).
• On 5 GHz try it 40 MHz or 80 MHz (more speed, but less range).

6. Common mistakes and their solutions

When setting up a Wi-Fi connection between routers, users often encounter common problems. Here are the most common ones and how to fix them:

If after all manipulations the network is unstable, try reset settings Reset the second router to factory defaults and configure it again. Sometimes errors occur due to IP address conflicts or incorrect settings.

⚠️ Attention: On some routers (for example, MikroTik) configuring WDS or Bridge requires knowledge of commands Winbox or SSHIf you are unsure of your abilities, use the graphical interface or consult a specialist.

7. When is it better to use a wired connection (LAN-to-LAN)

Despite the convenience of wireless connectivity, in some cases wired connection between routers will be the optimal solution. Consider this option if:

• 🏠 The distance between the routers exceeds 10–15 meters, and the walls are thick (concrete, brick).
• 🎮 You need maximum speed for online gaming, 4K streaming, or working with large files.
• 📡 You are using Wi-Fi 6 or Wi-Fi 6E — the wired connection will retain all the advantages of the new standard.
• 🔌 You already have a network cable installed (for example, twisted pair Cat 5e or Cat 6).

To set up LAN-to-LAN:

1. Connect the first router to the second one via LAN port (not WAN!).
2. On the second router, disable the DHCP server.
3. Set up IP address the second router in the same subnet as the first (for example, 192.168.1.2, if the first one has 192.168.1.1).
4. Set the same SSID and a password for uninterrupted roaming.

Advantages of a wired connection:

• ⚡ Maximum speed (up to 1 Gbps and above).
• 🔄 No packet loss or delays.
• 🛡️ Higher stability and security.

FAQ: Answers to Frequently Asked Questions

Is it possible to connect a router to a router without losing speed?

It is impossible to completely avoid speed losses in a wireless connection, since data is transmitted "in a chain". However, if you use 5 GHz and modern standards (Wi-Fi 5/6), losses will be minimal (10–30%). For maximum speed, it is better to use wired connection (LAN-to-LAN).

Which mode is better: WDS, Bridge or Repeater?

The choice depends on your goals:

• WDS — if you need one network with roaming and both routers support this mode.
• Bridge - if you need to flexibly configure the second router (for example, with another SSID).
• Repeater - if you need a quick and easy network expansion without complex settings.

Is it possible to use two routers with different providers?

Technically yes, but this will create two separate networks. Merging them into one will require additional configuration (e.g. VPN or special software). It is much easier to use routers from the same provider or configure one of them in mode client.

Why don't devices automatically switch between routers?

Automatic roaming only works if:

• Both routers have the same SSID and password.
• The device supports the standard 802.11k/v/r (most modern smartphones and laptops support it).
• The signal from the second router is quite strong (at least 50–60%).

If roaming doesn't work, try manually disconnecting from the network and reconnecting.

How do I reset my router if something goes wrong?

To reset your router to factory settings:

1. Find the button on the back panel Reset (usually recessed into the body).
2. Press and hold it 10-15 seconds (until the indicators blink).
3. After rebooting, go to the web interface at the standard address (192.168.0.1 or 192.168.1.1) with the default login and password (usually admin/admin).
