RBR750 Solid Magenta (no internet) after Xfinity Service Outage
I lost internet service during an Xfinity outage and my RBR750 system never came back online after the service outage. I use a personal DOCSIS 3.1 modem and my internet is fine when I am on LAN d...
- Thanks for the help. My router system is now working.
My MAC address was re-assigned to my PC during my troubleshooting instead of my router after the outage when service came back. I assume xfinity only allows one device to have access at a time.
A combination of modem reset and xfinity “reset” resolved my issue…I did these steps multiple times but it is important to do them together and in specific sequences.
I think the issue can be avoided by not plugging your PC directly to the modem when the initial device assignment occurs.
OK well if PC gets internet, shut down the modem and RBR, re-connect the RBR to the CM modem then power ON The modem and RBR. IF the RBR still fails to get connected and still has a front PINK LED, press the reset button in back of the RBR for 15 seconds then release. Walk thru the setup wizard on the RBR at 192.168.1.1 with the wired PC and web browser connected. Hopefully this will get the RBR working again...
Any Errors or Criticals seen on the Event logs page of the CM modem should be reviewed by the ISP and resolved.
This sounds exactly like what I had been going through. I would get all 0.0.0.0 for everything as well. And he is with Xfinity as well. I am going to talk to my neighbor to see if I can find out what xfinity did to their set up. I will try to get back to you all ASAP ( might be a day or so)

I think the issue can be avoided by not plugging your PC directly to the modem when the initial device assignment occurs. To get the sequence right, for troubleshooting only, if you connect the PC directly to the ISP Modem, Power OFF the modem for 30 seconds then back ON. This will get the PC to connect to the modem for testing. When you go back to connecting the external router to the modem, power off both modem and router. Connect then power ON the modem first, then router, then connect the PC to the router. You should need to reboot the PC however disabling the ethernet port on the PC for 10 seconds then back ON helps here if needed.
