I've spent countless hours trying to resolve the following problem.

After about 20-30 minutes of bandwidth usage I always disconnect suddenly. It stops my downloads, kicks me out of gaming servers, and halts streaming video.

The connection quickly re-establishes itself moments later, with no notification that it ever disconnected.

I've done all of the obvious recommended steps:

-I've updated the firmware on EVERYTHING. Modem, Router, COMM Ports, you name it.

-Disabled Firewalls to see if I still have a problem.

-System Restored.

-I've played around with nearly every setting possible in any menu. (I.e. the modem/router device manager advanced options, and the router's main page)

-I've run virus scans and spyware scans so brutally that they come up with nothing now.

-I've tried different Ethernet Cables.

-I've disabled TCP/IP Offloading

-I've lowered my MTU

-I've made sure that no dubious software was installed.

Some things I've done to try and diagnose the problem:

I ran "ping www.google.com -t" in the command prompt for a while and watched it one of the times I disconnected. It returns a Request Timeout.

I've run programs like Wireshark and Colasoft Capsa:

-Wireshark returns "Destination Unreachable (Port Unreachable)" Whenever the problem occurs and rarely, a "Malformed Packet" error.

-Colasoft Capsa constantly spams "Port Unreachable" and Checksum Errors.

I have a Linksys WRT54GL Router, With a Arris TM502G Modem, running comcast high speed cable.

What in god's name could be the problem? And what can I do short of buying new hardware or reformatting?

Please Help :(.
