Intermitent Connectivity issues
I've been having issues with connectivity for the past few weeks. This all started when Xfinity was "performing maintenance" in my area a few months ago to upgrade the network. Now it seems like the only thing that has been upgraded is more downtime instead of actually using my service. I bought a new modem, thinking this will solve the issue, but it did not. Here is what I'm seeing in the logs.

It would be greatly appreciated to get my service back up and running instead of restarting every hour just to function for a bit.

@Kulkathor1402 Thank you for reaching out on the Xfinity Community Forums. Are you seeing an issue with speed or just the disconnects since maintenance was performed?

You need to also post the modem's signal status values.
Please copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.
What is the exact make and model number of the modem ?

i have also been having CONSTANT disconnects, the internet connection never fully goes down it will just drop out briefly for a few seconds long enough to disconnect me from the game i'm playing and it is SUPER annoying and customer support is literally useless i think comcast is just a bad company

@user_37a8fc
Please create a new topic of your own here on this board detailing your issue. Thanks. For future reference, it is better to submit your own post as it creates a ticket to get help, and posting on someone else's thread can delay getting help.
