I had this issue with my SMC Router too. What would happen is that I would not be able to access the internet from any wired PC. The router was uncontactable either by web or icmp. The only recoverable action was to do a cold boot. This happens with my Linksys now too. I am connecting to the same network peers - Overnet. The fw is the latest from Hyper and previously I was using the fw from Linksys. It's a model 3 WRT54G router. I'm using G-mode and the default band. Any ideas guys? It;s not a overheating problem since i had the same issue with my SMC
Debug and get more data - does this happend to wired pc's or only wireless? Does it happen without Overnet? What if you put up a ping -t against a known internet IP address? Have you scanned for wireless interference? Whatever the previous router was doing wired is probably unrelated to what this one is doing wireless - unless the cable modem is the same. Have you replaced it?
