warcraft III disconnection problems

[chevelle396]

I constantly get disconnected from warcraft games, but never get totally disconnected from battle.net. It never happens on a constant time frame, sometimes it'll do it after about 10 minutes, sometimes later, sometimes not at all (but recently it happens every game). My computer connects to a Linksys 4 port router, which is connected to the cablemodem. When I connected directly to the cablemodem I didn't crash, but I only had time to play 2 games. Firmware is upgraded to latest, and my IP is the DMZ host.
