Xfinity app says my NETGEAR CBR750 is Offline, but is not

I activated a new Netgear CBR750 Cable modem a few days ago.

Activation using the Xfinity App went without any issues.  I can access the internet using my CBR750 home setup.  It is working great.

Problem is the Xfinity App home page shows:  "Your CBR750 is offline".  So, I Clicked the Xfinity App Internet Troubleshooting and clicked "Restart Device" button.  After a minute or so, message says "Your modem is unresponsive.  Let's try restarting manually"and also showed the CM MAC of my CBR750.  Clicked Continue button and followed the instructions to "Restart your modem".  Once the modem was powered back on, I clicked the "Check Connection" button.

After 5 minutes or so, it says "We're still not receiving a signal from your modem.  Let's schedule an appointment and one of our specialists will take a look".

So my internet service is working fine with the CBR750 cable modem.  I don't believe I need someone to come out to my house.

Any ideas why this is happening.  I've opened a case with Netgear for this issue also.

Thank you for your assistance.  I messaged Xfinity Support as you suggested.  The were able to confirm that my cable modem was online and working.  They were able to remotely restart it.  I can see the modem is online in using:  https://customer.xfinity.com/#/devices.

The issue appears to lie with the Xfinity App for iPhone not updating.  They recommended to wait a billing cycle to see if the app shows the correct status.

My Netgear shows offline too.  No firmware hooks for their phone app or website. 

Control it locally.  You might still be able to send a reboot signal from their end still.  That works on most modems/gateways 3rd party or not.

Same here.  All issues started last fall, after they upgraded their network and double the speed for free.  Xfinity app also shows my CBR750 offline too.  Even worse, every 3 days my download speeds drops to 1 Mbps and I have to restart my modem with the Orbi app or unplug it.  Netgear RMA my modem 3 times and still have these same issues.  After 3 months of of troubleshooting, Xfinity finally told me the CBR750 is not compatible with their new network until Netgear releases new firmware.

Same issue for me also. Your CBR750 is offline. They keep telling me it will self-resolve. Multiple calls over 2 months and no change. It affects how I can remotely access the modem and see it is working. For a rental property this is a deal breaker.

Hi, everyone up there! Have you resolved the issue? I recently bought this CBK753 set (CBR750 with 2 additional satellites), and am now experiencing the same issue. My Xfinity app shows it is offline, and my download speed suddenly dropped to below 1mb after 1 day. I had to restart the router to resume my speed. My plan is 1GB with Xfinity.

I'm thinking if I should return this CBK753 set and switch to a CM2000 + mesh wifi system, or maybe just get a CAX80 instead. Any idea? Much appreciated!

After replacing 3, CBR750, several months dealing with Xfinity & Netgear, and the 5th Xfinity tech came out to tell me that after Xfinity upgraded their network this modem is not compatible with Xfinity until Netgear releases a new firmware.  I returned the CBR750.  I purchased a Netgear CM1100 modem and Netgear RBR750 wifi router.  Which is basically the same setup but without the built-in modem.  The CBR750 satellites are the same as the RBR750 satellites which is RBS750.  With this new setup, I have no issues for the past months and can reuse my RBS750 satellites. 

You should definitely return your CBK753 and switch to a modem with a separate router mesh Wi-Fi system.  I'm staying away from the all in one modem, router, and wifi system.

@user_751b03​ I really appreciate your input here! That is really unfortunate to hear, sorry you had to go through all these back and forths. In that case, I probably should stay away from CAX80 too. I will try your standalone modem + mesh system once I return this CBK753 set. I feel either Xfinity or Netgear should be working towards fixing this, this is an expensive set of devices, and both Xfinity and Netgear list it on their website that the CBR750 is a compatible device : (

Anyway, thank you again!

I also have this same issue and have to reboot my CBR750 at least every three days. I wish Xfinity and Netgear would do something about this!
