Another CBR750 not working with Comcast/XF
Yo, Just came across your post.
So I'm reading through everything below, but I live in Thornton, CO and saw you're in Denver. I had Xfinity come out on 1/26/23 to do an "upgrade" to our net...
What Firmware version is currently loaded?
Please post a copy and paste of the modems connection status and event log page.

Really appreciate the follow up comment.
I’m ignorant to alot of this, so appreciate the info.
So reading through the comments and seeing what I saw on my speed tests, when my internet was getting kicked off I think the following is happening:
1. I was paying for 800 mpbs speed with Xifnity because I didn’t want to pay the price for the speed at the time and 800 should cover the needs of what our household needs.
2. I thought I remember reading that this model couldn’t handle 1 gig speeds and maybe Netgear would release an update down the road and I could choose to upgrade my speed should I need it/price with Xfinity was right.
The CBR750 can and does handle 1Gb speeds. Is a recent change to CC/XF ISP where they seem to have removed the 1Gb speed tier and gone with a 800Mb and a 1.2Gb tiers.
3. This xfinity upgrade last week has moved me up to 1gb speeds or close to it.
Can you confirm with the ISP that they have you at a 1Gb tier?
4. This model cannot handle these speeds causing my regular disconnects.
The model can handle these speeds, however there maybe isp signal line issues on the line that that could be causing problems for any modem. Just be cause your experiencing problems doesn't mean the CBR isn't capable. The problem needs to be reviewed first. Why we are asking for the cable connections and event logs pages for review here so we can help dermine and narrow down what direction that needs to be check in.
I didn’t know I could use a modem and thought I was forced to use the modem/router set up with this. Maybe xfinity can dial me back to 800 and I may look at getting the modem you mentioned.
You can use most most any mode with ISPs, you need to check with them first to see what they officially support on there network. However lets see if we can narrow down whats happening with the CBR first.
I was able to run the Cable Connection diagnostic two days ago, but this AM when I run the diagnostic, it shows nothing but a blank page. Was hoping to post images as requested but unable before I leave for work.
Connection sign on the admin side did read: Poor.
Let us know when you can post them.
Thank you.
Tech came over and didn't really figure much out. Checked the line and everything looked good outside. Said I was getting around 956 mpbs speed in, but he couldn't see or confirm a signal could be sent to the router, though everything was looking okay. He tried multiple times. installed a new splitter and new cables.
I was trying to show him some of the info provided by you and others in here, but we couldn't ever get the cable diagnostic to run anything and just kept showing Poor connection status.
He had to leave for another job, but gave me his number to follow-up. I did a factory reset on the router and the Cable Connection Status came back as Good. Attached is the summary I got.
Here is the Events Log. I tried clearing and refreshing but it's just blank. So not sure how/when new data will populate back in that.
I've rerun the cable diagnostic and then hit APPLY, but I keep getting an error message now that read: Invalid Frequency.
Here's the Events log I got before I cleared the Log on that.
