I have connected many of these up over the years, but this one puzzles me. The customers PC connects to the internet fine when connected directly thru the cable modem and ethernet port. When connect up the Linksys Router, you can winipcfg and release and renew to get a network address(192.168.1.101), but will not connect to the internet. All the lights show a correct connection. When you try to ping, it times out and doesn't even resolve the name to a network number. Tried reseting and even tried a static IP setting from AT&T. Went into Windows 98 and disable everything in the startup group and made sure there was nothing else running in the background. The status selection on the router does not show and IP address from AT&T. HOWEVER>>>when I hook this same router up to my network, running AT&T cable modem, it works fine. Does anyone have an ideas what would cause this?
