So I'm guessing this was my Christmas present from either NG or CC. I wake up this morning and find my modem with a solid led light showing at the bottom. So I opened a web browser and tried to get into the modem and was unable, I opened the network connection page of Windows and it showed that the modem wasn't connected as I had no IP address. I tried putting it in manually the IP for my computer and for the gateway (CBR750) and hit save, but was still unable to access the modem. It just timed out. So I unplugged the modem and waited about 5 mins, then plugged it back in and waited for it to come back online. Still has the solid white light on the bottom (photo attached). So I tried a factory reset and the modem went through the process (Never rebooted the lights on the front stayed solid the whole time, The only lights that blinked or changed color was the LED ring on the bottom) and came back to the state with the solid white light on the bottom. I tried this with both the coax connected and disconnected and
I again tried to get into the modem with no luck. (I then revert back to automatic DHCP from my PC and was still
unable to obtain and IP or gateway information) Seems like the modem is bricked. I found a oooooooold modem and set it up with CC and seems to be working with no issues and I can login to the modem with no issues. My CBR750 has been unplugged for over 8+ hours and when I plug it in (No coax connected) and wait for it to boot it gives me that solid white light at the bottom. After looking up what the lights mean. It looks like my CBR750 is resetting to factory default but never completes.And I am still unable to login to the CBR750 nor does it show connected to my PC (wired) and it doesn't obtain and IP address either.
