Try a factory reset (log in at 192.168.100.1 and reset to defaults) and see if it comes back, if not give it an hour - could be an upgrade happening to your node (since it's early morning) or could be a local issue. If it's still happening in a couple hours please contact email@example.com and we can get a ticket open for you. Thanks.
Just few min ago my modem just stuck and can't seems to be able to sync it was working perfectly few mins ago , cable modem dcp3000 2nd light is blinking continuously
If you know anybody with cable TV or cable internet, you could try bringing your modem to their place to confirm that it still syncs up there. That will confirm that your modem is still working, which is always helpful to know. -- electronicsguru.ca
