've been trying to help a couple of friends with identical problems. They both have Comcast cable internet but are using a netgear and a linksys wireless routers. The laptops are using Windows Xp Pro with SP2. They both have 2 desktop PC's that are connected to the network and are working, one wired and the other one with wireless PCI card. The laptops suddenly cannot obtain an IP from the router no matter how many times I did an ipconfig /release and renew. I also did a NETSH WINSOCK RESET CATALOG. I also downloaded WinsockXPfix and ran the program but still get the error limited or no connectivity with a yellow triangle and exclamation point on the icon in the system tray. One weird thing is the other friend's laptop cannot connect to the internet even when connected via ethernet cable.
I've done this fix before and I don't know why it won't work this time. I also downloaded and installed an MS patch windows xp KB-884020 to no avail. Any help will be greatly appreciated.
Has anyone resolved this issue?
