CBR750 not working with Comcast/XF
Having the same issue in Denver thanks to ISP "upgrades" from comcast. Just messaged Blanca_O . Keep me posted on progress please.
There we go...
I see a few channels that are a bit over the power range recommended by NG:

I'd ask the ISP to reduce the power on the line a bit. Ask about a inline attenuator to help here. Up link is 5dbm so if they can get the down link around same, would be good.
Have some Correctables but not horrible. Be sure to check all coax cable fittings and ensure they are screwed in to the jack in back well and snug. Be sure coax line is of good quality RG6 cable. Check for any coax line splitters as well.
Also what FW version is loaded on the RBS and CBR?
There is newer FW for both if you haven't already loaded them:
Be sure to update the RBS first then CBR lastly.
Are you still on the 800Mbps speed tier from the ISP?
Thanks FURRYe38 I will call comcast when I get a chance. One of the steps their tech took was to move the Modem directly to where the coax lines come into the house so we should be good there. I am still on 800 speed with them, yes.
As for firmware see below:
