Model: Archer C6  
Hardware Version: V3
Firmware Version: 1.0.14 Build 20211118 rel.43110(5553)

I have one TPLINK router Archer C6. I am trying to use it as extender. I have assigned a static IP to it to be in the family network. It works OK most of the time. But sometimes (for example, the main router restarts) it behaves weird. Its IP reset to following:. Initially i have assign this to IP 192.168.1.2. I have tried working with reset the device and upgrading to latest available firmware also. But same issue persists. Please help to understand what is going wrong.

 

While configuring the router i have assigned a fix IP to LAN. Disabled DHCP and in System Paramters enabled 5Ghz WDS.

 

This is configuration when it works OK.

This is configuration when router restarts or do not know why it behaves so weired.

Try setting the Archer C6 with a static LAN IP 192.168.1.254 and test again the network stability.

The IP addresses of 169.254.X.Y subnet is given when the device can't get its IP address by the DHCP server (WDS failed, most probably because of restarting the main router).

  @terziyski Thanks for your response. Looks you are right that the problem occurs when main router restarts. Setting a static LAN IP 192.168.1.254 does not help much here.

If you comeup with any other solution then please let me know.

There's nothing much you can do - when the main router restarts the WDS breaks and the reason your Windows computer is getting an auto-configuration IP address 169.254.x.y is that it can't receive an IP address from the main router DHCP server. Restarting Archer C6 too, would help re-building the WDS again.

It's incredibly frustrating to continually reset and reconfigure the router.

Restarting this TP-Link router while keeping the main router operational hasn't provided much help. In fact, if I turn off the TP-Link router for the entire night (with the main router still up and running), the TP-Link router loses all its configuration settings by the morning. This is becoming a significant inconvenience, as I have to go through the entire setup process from scratch each time.

I’ve tried updating the firmware and adjusting various settings, but the issue persists. Do you suggest any other setting which can help here?

You could try one more thing to improvove the stability of the WDS.

Set your main router 5GHz with a static wireless channel like 36 (for example). This could improve the stability of the Archer C6 WDS connection.

When you loose access to C6 you could connect directly to its LAN port doing the following:

Given that C6 has its static IP address 192.168.1.254, set your computer with a static IP 192.168.1.253 and connect to C6 LAN port.

Browse the C6 WebGUI and check its settings. When you've restored C6 WDS, revert back your computer LAN adapter (DHCP) settings.
