Its a dell latitude d610. I've replaced the wifi card and that didn't fix the problem. I contacted Geek squad and they said it most likely is a setting problem. At some point, either myself, my parents, or a friend changed a setting but i have done a system restore and that didn't fix the problem. I've restored all the settings where the option was given and that hasn't fixed the problem. On both the wireless and LAN connections it says firewalled. Any ideas of what the problem might be?
