Sometimes my computer loses its connection to the internet. The connection status box says it's connected and it has the IP address and all that stuff. The problem happens randomly (at least once a day) and goes away after a short period of time. I called my ISP and they were not able to fix the problem. I've also tried changing the cables and connecting my computer directly to the cable modem. I am using a Linksys WRT54G router and a Motorola SB5101 modem.
