Model: TL-WA860RE  
Hardware Version:
Firmware Version:

After connecting the device the WiFi worked fine but a separate problem came up. A computer (Windows 10) that's connected via Ethernet to the same network (it's not connected to the extender but to the router itself) has connectivity issues. 
"Ethernet doesn't have a valid IP"

Thought it was a system issue so we did any troubleshooting step imaginable. Nothing worked until we pulled the WA860RE out of the wall. We thought somehow both devices had accidentally gotten the same IP. We reset it and tried again checking that both have different IP addresses which they had. Everything worked fine until one day later where we had the same problem that only got fixed by pulling the repeater out again. 
Does anyone know why this happens since both of them are connected separately and should work independently from one another. 
and is there a fix?

Hi, May I know the current hardware and firmware version of the TL-WA860RE?

How to find the hardware and firmware version of my TP-Link device

Is the Ethernet PC the only affected device? Are you able to get internet connection from router on other devices?

If most of the devices failed to get internet from the router, the current issue is quite like the following post:

Wi-Fi Range Extender Causing Host Router No Internet

Wait for your reply and best regards.
