@Basboi85 thank you for your help and clear explanation. When I tried first on my data it gave me some weird error but that must've been due to me switching between wifi and data and the connection...

I got a second hand archer ax55 today, set it up, connected it to my TP-Link ID and discovered the tether app. it worked perfectly fine, but when 00:00 struck Wi-Fi shut down for all of my devices....
