The extender connects to the internet just fine but after a couple of hours its impossible to connect to the extender, not via WIFI nor ETHERNET cable.
It seems unpluging and plugging it back on fixes the issue for some time, I have tried factory reset, updating frrmware, diabled DHCP, changed IP Adress, DNS.

When this problem happens all lights of the extender are on so I asume it still has connection to the router...
I dont know what else to do.
