My tplinkap arrived; good signal where required; both 2.4 and 5 GHz
However can' t change from default username and password. As I login, using the default, I am prompted to change them. Enter new username, password and retype password (high strength and green tick to show match) but when I press confirm I get failed. Tried several times to logout and back in but failure each time.
Changed 2.4 SSID and its password sucessfully so know I am talking to unit.
All this via wifi..
Also tried to go through account management but get failure there.
Any advice please
