How to Extend WiFi Coverage Using WDS Bridge Mode on Your Router

If you have a spare router collecting dust, WDS (Wireless Distribution System) bridge mode can turn it into a free WiFi range extender. Unlike a plug-in range extender, a full router running WDS gives you more control, more Ethernet ports, and generally better performance. The catch: it takes a few careful steps to set up correctly, and there are some real limitations you should know before you start.

What Is WDS Bridge Mode?

WDS is a protocol that lets wireless access points communicate with each other directly — wirelessly — without needing a wired backbone. In bridge mode, your secondary router connects to your primary router over the air and rebroadcasts the signal to devices in a new area of your home. The result is the same WiFi network, extended into a room your primary router couldn’t reach.

It’s worth understanding how this differs from other extension methods. A wired access point connects to your router via an Ethernet cable and is always the best-performing option. A mesh system (like Eero or Google Nest) uses a proprietary protocol designed for multi-node setups, with automatic handoff and easy configuration. WDS is the older, more manual option — but it’s free if you already have compatible hardware.

WDS Limitations to Know First

Before setting anything up, be aware of these hard constraints:

Throughput is halved at each hop. Because the secondary router uses the same radio to receive and retransmit traffic, your devices connected to it get roughly half the wireless bandwidth of the primary router. On a 400 Mbps connection, expect about 150–200 Mbps at the secondary node.
Same band only. Both routers must bridge on the same frequency band. You can bridge 2.4 GHz to 2.4 GHz, or 5 GHz to 5 GHz — but not 2.4 GHz to 5 GHz.
Same channel required. The primary and secondary router must use the same WiFi channel on the bridged band. If one uses auto-channel selection and changes channel after a reboot, the bridge will drop.
Cross-brand compatibility is not guaranteed. WDS is not part of the official Wi-Fi certification suite, so routers from different manufacturers may not bridge reliably. TP-Link to TP-Link and ASUS to ASUS work well. TP-Link to ASUS is hit-or-miss. Using the same model on both ends eliminates this problem entirely.
Roaming is manual. Devices connected to WDS networks do not automatically switch between the primary and secondary router as you move around (the “sticky client” problem). Mesh systems handle this automatically; WDS does not.

What You’ll Need

Two routers that both support WDS (check your router’s firmware settings under Wireless)
The MAC address of your primary (root) router’s wireless interface
Access to both routers’ admin panels
A laptop or desktop connected via Ethernet to configure the secondary router

Step-by-Step WDS Setup

Step 1: Find Your Primary Router’s Wireless MAC Address

Log into your primary router’s admin panel (usually 192.168.1.1 or 192.168.0.1) and navigate to the Wireless or Status page. Note the MAC address of the wireless interface on the band you plan to bridge — it looks like AA:BB:CC:DD:EE:FF. Write this down; you’ll enter it on the secondary router later.

Step 2: Lock the Primary Router’s WiFi Channel

WDS requires both routers to stay on the same channel. Go to your primary router’s Wireless settings and set the channel to a specific number — do not leave it on “Auto.” For 2.4 GHz, choose channel 1, 6, or 11. For 5 GHz, choose any fixed channel your hardware supports (e.g., 36, 40, 44, or 48 for the lower UNII-1 band). Write this channel number down.

Step 3: Configure the Secondary Router’s IP Address

Connect a laptop to the secondary router via Ethernet. Log into its admin panel and navigate to LAN settings. Change the LAN IP address so it’s on the same subnet as your primary router but doesn’t conflict with it. If your primary router is 192.168.1.1, set the secondary to 192.168.1.2. Then disable DHCP on the secondary router — the primary router will assign IP addresses to all devices. Save these settings; the admin panel may disconnect briefly when the IP changes.

Step 4: Enable WDS on the Secondary Router

Still in the secondary router’s admin panel, navigate to the Wireless settings for the band you’re bridging.

TP-Link (new UI): Go to Advanced → System Tools → System Parameters and find the 2.4 GHz or 5 GHz section. Click Enable WDS Bridging, then click Survey to scan for your primary router’s SSID. Select it, enter the WiFi password, and set the channel to match.
ASUS: Go to Wireless → WDS tab. Enable WDS, select the band, enter your primary router’s SSID and wireless MAC address, and enter the security key. Set the channel to the fixed channel you configured on the primary router.
Netgear: Some Netgear models support WDS under Advanced → Wireless Settings → Enable Wireless Bridging. Enter the MAC address of the primary router and match the channel.

In all cases, the SSID, security mode (WPA2 recommended where available), and WiFi password on the bridged band should match your primary router exactly, so devices see one seamless network name.

Step 5: Verify the Bridge is Active

After saving, check the WDS status in the secondary router’s admin panel. On TP-Link, navigate to Advanced → Status → Wireless and look for WDS Status showing “Run.” On ASUS, the WDS page shows a link status indicator. If the status shows “Scanning” or “Disconnected,” double-check the MAC address and channel settings on both routers.

Connect a device to the secondary router’s WiFi network and run a speed test using our WiFi speed test tool. You should get speeds roughly half of what you see when connected directly to the primary router.

Troubleshooting Common WDS Problems

Bridge Won’t Connect

The most common cause is a channel mismatch. Confirm both routers are set to the exact same channel (e.g., channel 6 on both, not “auto” on one and “6” on the other). The second most common cause is an incorrect MAC address — make sure you entered the wireless MAC, not the WAN or LAN MAC, which are different on most routers.

Speeds Are Very Low

If you’re getting speeds far below 50% of your primary router’s output, signal strength between the two routers is the likely culprit. WDS bridges perform best when the secondary router is close enough to the primary to maintain a strong signal (−60 dBm or better), while still being far enough to cover a new area. Position the secondary router at the edge of your primary router’s reliable coverage zone — not at the extreme edge where signal is already marginal. See our guide on WiFi signal strength and dBm for how to measure this.

Devices Won’t Roam Between Nodes

This is expected with WDS. Your phone or laptop may stay connected to the secondary router even when you walk back near the primary, because client devices control roaming decisions, not the router. One workaround is to temporarily disconnect from WiFi and reconnect, which forces the device to associate with the nearest access point. For automatic roaming, consider upgrading to a dedicated mesh system or adding 802.11r (Fast BSS Transition) support via third-party firmware like DD-WRT. Our guide on fixing sticky client roaming covers this in depth.

When WDS Is — and Isn’t — the Right Tool

WDS makes sense when you have two compatible routers already, can’t run an Ethernet cable, and don’t need seamless roaming. It’s a solid free upgrade over a cheap plug-in extender because you get full Ethernet ports on the secondary node and better radio hardware.

If you’re buying new hardware anyway, a mesh system is almost always the better investment. Systems like the TP-Link Deco or Eero handle multi-node coordination, roaming, and backhaul automatically. If you can run an Ethernet cable — even temporarily through a doorway — a wired access point beats WDS for throughput. And if running cable between floors is impossible but you have coaxial outlets, a MoCA adapter solution delivers near-wired speeds without any wireless throughput penalty.
