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.
What Firmware version is currently loaded?

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
Is the front LED PINK?
Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?

Plug in and turn on modem. Wait 2 minutes for it to connect.

Which port on the CM modem is the RBR connected too. Be sure the RBR is the only wired device connected to the CM modem. RBR should be in port #1 and the other port should not be used. Can try swapping ports after you power cycle the CM modem off then back ON for 30 seconds.
All LEDs on the CM modem good? Should be green and Ethernet LED should be blinking green.
Tried LAN 1 and LAN 2 and no change.
Modem LEDs are good.
Try this, power OFF the CM modem and disconnect the RBR from the modem. Connect 1 ethernet PC to port 1 on the CM modem and power it on. After say 2-3 minutes, can the PC gain access to the internet?
Please post a copy and paste of the modems connection status and event log page.
