I bought a wireless adapter from TP-Link. It's a model TL-WN822N. It is compatible for windows 8 and as far as I know I have installed the drivers correctly, but I must have done something wrong. Right now I am getting 3.5 Mbps, but I know I should be getting a lot more. The wired computer in the other room is getting around 16 Mbps so I should be able to get at least 10 Mbps out of this thing. Can someone please walk a newbie through the steps and see if I can boost my speed a bit? It should definitely be faster.
