>>Hi,
>>
>>I have been connecting my computer to internet via Wi-Fi (router) for a long time. And I just changed the ISP from Comcast Business to Comcast Home. So, I got a new Comcast modem. The person in the Comcast office assured me that the speed of the Comcast Home will be as good if not better than Comcast Business. This kind of works sometimes, and does not work other times. I have not yet figured out what is the problem, when there is a problem.

>>Meanwhile I decided to try connecting the computer to the Comcast modem directly, using Cat 5 cable. But, after I connect the computer to the modem with Cat 5, and disconnect from wireless, I have no internet connection. How can I tell or test if my computer is connected to the Comcast modem directly?

First check firewall enabled and hosts file - without router there is no NAT and/or firewall (except perhaps/probably windows-own) between him and attackers out in the net. In W2K times usually 20s before somebody starts sniffing for openings.
Check rubber suit first before entering unknown regions... somewhere else proxies could be hiding ?
