I have a Windows XP machine that was working fine last night but today when I turned it on it can't connect to the internet through my ADSL modem router. Another PC that uses the router is working fine.
Initially, the "a network cable is unplugged" message popped up in the system tray and kept flickering as if it kept getting disconnected.
I've tried reseating both ends of the network cable, and using a different port in the (4 port) modem router.
I've tried rebooting.
I've tried turning the modem router off and on
I've tried "Repair" on the Local Area Network connection, and I got the error "Windows could not finish repairing the problem because the following cannot be completed: Renewing your IP address"
What can I try next? Thanks!
