I'm on Comcast, Mont County MD. XP with SP2. Problem is on my desktop that is connected (coax) to the wireless modem that services my laptop. I get occasional and very short service interruptions - IE will suddenly ask if I want to dial up (it seemingly does not remember that I say "never dial up a connection") and other apps will lose their internet connection briefly. This seems to be related to the fact that I installed a new SB5100 modem recently. The log there will show that:
Looks like Comcast fails to respond in time. Whats up? Anyone else have this? Is there a timeout setting?
