I recently got a BEFSR81 to share a cable connection, and at one point it worked. Then I unplugged it for a while, and now suddenly it won't work. Computers connected to it can't ping or browse to 192.168.1.1 - or even to eachother. They can't lease IPs from the DHCP server. In fact, they can't do much as far as networked PCs go. I've reset the router several times to no avail. I'm sure it's not the computers themselves, as they go through a regular hub just fine. Anyone have any ideas?
