Another CBR750 not working with Comcast/XF

My plan with Xfinity is 800 Mbps.

Orbi firmware CBR750:  V4.6.14.4_2.3.12

I'll have to post/copy the other details when I get back home this afternoon.

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.

Ran the event log this AM and only had this error message hitting.  Xfinity is still showing they cannot detect/send a signal to the Orbi 750.

Hey Fury,

So after the factory reboot on 2/8, Xfinity was never able to detect the Orbi router.  Frustrated, I just left it as it was because at least the internet was back up after the reset.

Left the house today to run errands and got back home to find the wireless, once again down.

I've rebooted the Orbi from the app on my phone and have wireless back up.

Attached are by Cable Connection and Event Logs below. 

I tried contacting Netgear on their website to file a claim/inform them with case ticket on this issue because kept getting error messages when I tried to submit, so I gave up.  What is the best/direct way to contact them to let them know that my unit is having issues like other adopters of this product?

A user messaged me that had similar issues like others with this and ended up renting a modem from Xfinity. For them, begrudgingly, that seemed to solve the disconnects and a signal is now registered.

If there are any suggestions you see from the Event Log page, I will share them with Xfinity and see if they can address it.

I'm going to give this another two weeks to see if a solution can be found, either with my ISP addressing the issue or NetGear can provide the fix.  I'll even consider buying a modem if that corrects it.  Spending over $400 on a product that is not performing like it should is frustrating to say the least and hope NetGear can address my issue.

Thanks again for your help.  It is much appreciated.
