I have bought the D-Link DIR-635 wireless N Router and installed. It works great on my friends mac but it dosent work on my dell dimension 8400. I have the D-link airplus xtreme g dwl g520 wireless card in my computer, and i have tried to install a new driver. I can find the wireless signal in local wireless connections, but I cannot get to where I have to right the code Ive made. And the one time I got there, and wrote the code, it still didnt join.
