I have the Linksux 2.4 GHz wireless B adapter for my pc and a standard DSL Westell Modem and 2.4 GHz D-Link router.
AND IT SUCKS!!
Ok, so heres the deal, the internet itself isn't the worst, its slow, (dl'ing and up'ing takes FOREVER) but all in all it 'works' Though, I am big gamer, namely Counter-Strike 1.6 and I have the worst connection with it, I can rarely connect to the steam client and when I enter a server, my ping is always below 70 but I lag spike every few seconds. For some reason my wireless feed keeps getting interrupted.
