Recently i have bought tp-links wireless adapter ( model tl-wn8200nd ), and i have loads of trouble with it. Few times a day it just disconnects from wifi, and i cant connect for few hours. I have tried pulling usb in and out, restarting computer, rebooting rooter. It cant connect to anything, my wifi, my phones tethering wifi, neighbors wifi. Also if i try to connect from windows its pop out window says 'Windows was unable to connect to (insert wifi name)', and if i try to connect threw tp links utility program, it keeps asking for password saying it might not be correct, even thoe it is, because it reconnects after a while. Its not a problem with rooter because my phone and my laptop dont have these kind of problems.
