when I connect with a LAN cable to my extender, I have normal internet access. But, Wifi of the same extender provides no internet connection. Over wifi I can access the device settings, but internet connection is not available.
Whe I login in tplinkplc.net as admin and reboot the extender, Internet access through the wifi becomes available for a few hours and then stops working again...
This problem started appearing a week ago - I didn't make any changes to to setup of my home network (no new rooters, access points, power line adapters & extenders...). Before the problem started occurring, the adapter and extender were working fine for several months.
What can I do to resolve this issue?
