This is a weird problem that others may have too: My connection to the Internet (cable) goes dead if I leave my laptop on without using it for some time. The error message says “ARP cache will not clear” when I try to refresh the connection. I have tried it with both a wireless and Local Area Network connection, but both exhibit the same problems. My OS is Windows XP SP2 and I have all manner of security in place. Any help will be appreciated! Tried to read MS help page re:asp but is too nerded for me.
