Hi

I bought a new TP-Link Archer C80 a few days back. I set it up through the Tether app and everything works fine, but for whatever reason I can't access the web-based interface. I can enter to the log in page, either through tplinnkwifi.net or the IP adress, but as soon as I log in, it logs me out within a second. I've tried to log in with my TP-Link ID as well but the same happens. 

If someone knows how to solve this issue I'd be grateful.

PS: As I could't chosse the exact model of my router when creating this thread and it won't let me continue without selecting one, I've chosen a random model (Archer A10).
