Archer C7 v4.0 not working with TL-WA854RE
2023-06-27 18:44:17
Model: TL-WA850RE  
Hardware Version: V4
Firmware Version: TL-WA854RE(EU)_V4_1.0.12 Build 221109

Hello i recently bought a TL-WA854RE to extend wifi provided by Archer C7 v4.0 frimware version 1.0.8 Build 20190411 rel.65590(4555). Using different SSID for each. But after pluging in the extender the old wifi "stops working". I am able to connect to it, but it says "no internet". It starts to work after 5-10 minutes. It looks like it takes forever to receive ipv4 adress from the router. It works fine with the extended wifi, which is weird because i disabled DHCP on the extender so I gues the router is taking care of that now.

 

After unpluging the extender the old wifi works fine. Any idea what the problem is and how to fix it?

Hi, the Archer C7 supports both 2.4G WiFi and 5G WiFi, while TL-WA854RE only supports 2.4G WiFi, please confirm if it is the router 2.4G or 5G WiFi stops working when the extender is plugged in, or both?

 

Please try to change WiFi channel and channel width on Advanced->Wireless->Wireless Settings page of the router, then check if there is still the same issue.

  @Sunshine thank you for replying. I only use the 2.4 WiFi on the router. The 5G is disabled.

 

Both of those settings are set to auto. Using wifi scaner i can see I am the only one using channel 2. The current width is 20 Mhz. I am living in a small village so there is really not that much wifis.
