Model: TL-WA855RE  
Hardware Version: V5
Firmware Version: 221109

Hello,

 

I have a problem with my lan network not working caused by the WiFi extender.

Recently I bought a TL-WA855RE extender with v5.0 hardware and latest 221109 firmware. I use this extender to catch up my WiFi signal and connect the TV with LAN cable to it.

 

The problem is that on every restart of my PC (which is connected to the router with LAN cable) my internet stops working until I either restart the router or the extender. When I plug off the extender and eliminate it from the network the problem disappears.

 

NOTE: When this problem occurs, the WiFi from the router continues to work properly. Just the LAN ethernet does not.

 

NOTE: I've tried to connect my laptop to my router with LAN cable and the same thing happens with it, so it is not from the PC.

After 2 days of testing I can confirm that updating the firmware of the extender worked. Thank you once again brother!
