Hah...My family had trouble with our modem for over a year. If we couldn't fix it by waiting or resetting the modem or disconnecting/reconnecting the cables, we'd call the provider. This was followed by testing it elsewhere in the house, pressing the reset, powercycling, etc. Nothing worked. Sometimes we'd shut down the entire network and bring it back up in a particular order. After a while that didn't work either. Finally, the people at the provider found out we had a router. "Oh, that's your problem. You shouldn't have a router connected to the modem" ad infinitum. Yeah, right. We had problems really early on (pre-router) and they'd offered to replace the modem. They hadn't. The problem was in the modem all the time. We finally went out and got a combination of a router and modem and it worked much better.

A quick way to make sure the problem is in the router would be to try sending something large between computers. (OK, might not work anyway due to Mac and Windows "compatibility," but worth a shot.)I f it works, the problem might not be the router. If it doesn't, get the router checked out by a pro.
