I'm currently using my iPhone 3G's 3G connection. Last night, I had some PC troubles, and to make a long story short, I had to reformat to Vista, and my PCI-E WiFi card. My crappy USB thing works, but not quite. Now, I messed up even MORE. I accidentally changed the WEP/WPA key, and I forgot it. Because of that, NO computers in the house can connect to the router. WTF do I do?
