I'm having a giant issue with my ubee modem that comcast installed last month and my Cisco E 4200. I had a Dlink extreme router when they first upgraded my modem to the new ubee modem. After a week the router and the modem stopped communicated. I still had internet if i hardwired to the modem with the laptop and could still access the lan. I thought it was old and just went, so I replaced it with the new cisco e4200 and that was great for about 2 weeks, then it did the same thing after a windows update on my nic and wlan card on the laptop. I went through the trouble shooting with cisco on the phone and they recommended returning it and getting a new one. So I did and then tonight I set up and then went to hook in my hard lines for the 360 and ps3 and the same thing happened again. No communication between the router and the modem but I can still access the internet directly through the modem and I can still access the lan. Please help I think it's the modem but I'm not sure at all now.
