Hi Hope someone can help. I have Comcast internet. I set up a wireless network using a Netgear router about 2 years ago. No problems until this week. I had to send my laptop in for service. Since getting my laptop back, I have been unable to connect to the internet at home using my laptop. When I try to connect to the internet it says "page not found." I can connect to the internet with my desktop. Also, when I use my laptop at school it connects to the wireless network and internet with no problem. I've clicked on the wireless network icon in the system tray. Status says "Acquiring network address." When I click on support Address Type: says Invalid IP address. IP Address is 0.0.0.0 Subset 0.0.0.0. When I click on "Repair" is first says "Connecting to wireless network" then it says "renewing your IP address", but then it just sits there. I've left it running for over an hour is it still says "renewing your IP address." I'm running windows xp on my laptop. Please help! Thanks!
