Just a note… if you have Tomato installed as firmware in the router and Comcast cable internet then try followings:
- Disconnect cable modem and router and wait until their lights go off. For Comcast modem it takes fair bit of time because of internal battery.
- If Internet connection is still lost then connect your computer directly to cable modem. If this doesn’t work then you need to call Comcast at 1-800-COMCAST.
- If above works then the problem is that your router isn’t syncing with cable model. To confirm this, log in to router login page usual http://192.168.(0 or 1).1. See the status in overview. If this status is "Renewing…" and never changes then disconnect cable co-axial wire going to model. Turn off cable model. After all LEDs goes off turn it back on. Reconnect cable co-ax to it.
