I use a Dell PC running windows XP professional, and internet explorer. I turn on my computer, and it automatically connects to my wireless network. It says it's connected and that the connection is "excellent" but I can't actually work online. I've tried plugging directly into the wireless router, directly into the modem, and connecting to different available networks. Even though it says I'm connected, I get "The page cannot be displayed" message! Neither of my roommates have a problem connecting to our netowrk. . .I called and had the network reset, and that didn't help either!
