Does anyone have any idea what might cause this problem? My roommate and I have 2 G5s hooked up to a Netgear MR814v2 router (wired) and an iBook too (wireless). We have a motorola cable modem and Comcast for a provider. All three computers will randomly lose the internet connection. We can still access the LAN, though. If we power cycle the router, it is fixed, or it will come back up in 15-30 minutes or so if we don't. Comcast wants to blame it on the router, but I have a suspicion it isn't. Anyone have any idea what might be causing this?
