Random internet disconnects on wifi and ethernet
Hi,
My internet has been disconnecting randomly for over a month on multiple devices (computers, ipad, phone) on both wifi and ethernet. A tech came out and installed a new cable outside to my house and a new modem but it didn't fix the disconnects. The modem has a direct coax connection to the outside coax cable. I've reset the modem and gone so far as to reinstall Windows on one of my devices to troubleshoot any network adapter issues. I didn't have any problems for years until a little over a month ago and nothing has changed in my house. I'm even having trouble submitting this question because the internet keeps cutting out.
Any help would be appreciated.
Thanks

A volunteer (not a Xfinity employee) responded to my post asking for information about my modem specs. Their post and my response have been deleted. What's up with that and can anyone help?
It seems the issue I'm experiencing is not unique and is likely a Xfinity network problem or a firmware problem with the XB8 modem as in these other posts:

Hey @user_a56b4b, Thank you for visiting our official Xfinity Forums Community support page. We greatly appreciate you taking the time to share your experience regarding the Xfinity Internet service. I would be more than happy to offer my assistance looking into this further for you.
Would you be able to visit our 'Tips for troubleshooting your Xfinity Internet connection' knowledgebase page to find out how to gain access to the Admin GUI to review the signal levels of the modem? You will be able to see the signal level specifications listed. You can compare your signal level readings to what is shown in the support page. If possible, please provide a screenshot or post the information so we can review as well.

Cable Modem
This is what I can see from the admin GUI.
The number of downstream channels fluctuates wildly as seen here when I refreshed the page:
Lots of uncorrectable codewords as well
