I just purchased the Linksys WRT54G to hook up wired to 2 computers running off of Comcast cable. Every few minutes the connection will drop on both machines. I have updated the firmware accordingly and it has not helped. A call to Linksys prompted me to clone the MAC address but that also did not help. I can either reset or turn off the router to get my connection back for several minutes, then, back to the problem. If I run the modem straight to either machine the connection is rock solid. And this is my second router as well... Someone please help me on this situation.
