Ok, this happens on more than one computer. It happens on a desktop with Windows Vista, a marvell yukon lan adapter, and a belkin 802.11g wireless card. It also happens on a thinkpad x41t under ubuntu using the built in atheros wireless card. Haven't tried wired or windows with it. After a certain amount of time (I think the timeout time) my computer will partially lose internet connection. It's only partial, as AIM still works, but my internet browsers won't, nor will my desktop widgets. Release/renew doesn't fix things, only rebooting the computer does. It happens with more than one version of the tomato firmware. I was using one of the original versions up till recently, and am now on v1.07.1039, both of which have the problem. I'm using a buffalo WHR-HP-G54 router. Any help in solving this issue would be appreciated.
