Please help! I have insightbb cable modem service and a linksys wireless access point router (BEFW11S4). I have two desktops connected with ethernet cords and one laptop that is connected with a linksys wireless card. This set-up works perfectly and all the computers can connect through it. However, I take my laptop to another location (a library with a wireless network for public or to my friend's wired router network) and I CANNOT connect even though it works fine in my home. I'm running windows xp and when i do an ipconfig /all nothing shows up and the computer gets all confused when i'm on an outside network. Does anyone out there know what is happening? ALso....if i try to connect any of my computers DIRECTLY to my cable modem in my home network, it does the same thing and will not work. I am frustrated completely!
