Hello, i have to say i started having quite a bit of problems with this.

When i brought it, it worked just fine i had the drivers via cd and it detected normaly, but i threw away my pc and got a new one and i found out that i lost the cd somewhere, so i decided to download the drivers on the site. Well i tried v2 and even v3 (v1 doesnt really have any setup, atleast in the windows version) but both couldnt detect the usb and i couldnt download the drivers. Im using windows 10 and so you know, windows normally registers the usb and calls it : TP-link wireless USB adapter. There isnt a problem with not having a wifi or something. It uses the wifi driver thats in windows 10 by default but i feel like this takes a lot from the usb, because our wifi, thats normaly 40mbps without any trouble is only around 400kbps at max.

Thanks for every help.
