Ok so yesterday I get home from soccer practice expecting to go online with my laptop and it won't let me. It says I don't have a connection. My wi-fi is on and everything. I clicked "diagnose why windows can't find any networks and it said, "this computer does not have a wireless network adapter installed and configured." My internet was working fine 2 days ago! I checked for driver updates and scanned for viruses and even did the ipconfig/release and renew thing. I have widows vista and get internet through a wireless adapter, if that helps.
