I have been running into computers running Windows Vista that are experiencing a problem with slow surf issues when dealing with a cable modem. For some reason, when I ping a web site on these computers, they will ping fine for the first few packets and then it will ping itself and give an error message of unreachable destination. I know it's not the cable modem because I can plug another computer into the modem and it works fine and pulls a different IP address from what the other computer is pulling. The weird part is that I can plug a router to the computer running vista, and it will surf and ping the internet just fine. The problem just occurs when plugging the Vista machine directly to the cable modem itself. Anyone have a solution to the problem or have seen this problem occuring?

Windows Vista computer won't stay connected to the network or internet for more than 15-30 minutes at a time

Click Start, Control Panel, Network and Sharing center, Manage network connections and right click Local area connection and select properties. Untick the box next to Internet Protocol Version 6 (TCP/IPv6) and see if you can connect.

I tried disabling all firewalls, antivirus, and IPV6. It will connect but has excessive packet loss due to Vista trying to send the packets of data to the computer itself rather than to the web server for the web page. The pings are stating destination unreachable because Vista is trying to send the packets to itself rather than to the web server.
