Unstable Internet (wifi and ethernet)

It happens on all devices. I have tried factory resetting the router and tightened up all the cables and straight them out I really can't figure out why this keeps happening

I really appreciate those details! Did this recently start happening? Have you sent any troubleshooting signals using our Xfinity app?

I did try a few times but the Xfinity AI just tells me my connection is fine and that there are no outages in my area.

@user_l7i04e thank you for the follow-up that you've run through troubleshooting through the Xfinity App. Have you by chance checked the modem signal levels yourself by going to view your modem’s status page go to http://192.168.100.1 or http://10.0.0.1

This helpful forum post shows where the signal levels should be when they are within the specification levels https://forums.xfinity.com/conversations/your-home-network/internet-troubleshooting-tips/602dae4ac5375f08cde52ea0

I did try a few it does seem to happen less after a factory reset but it's still happens sadly the Xfinity app only tells me that everything is running fine. I will have to actually get a hold of a agent to ask for details because even using the admin tool doesn't show me what I'm looking for.

I am experiencing drops from the service on a hard wired connection and it is due to your WAN. Specifically you have drops, a flapping interface, or errors on your route at the following devices for me. it is within your network and then your upstream provider. I opened a ticket about this less than two weeks ago ([Edited: "Personal Information"]) and it is back:

I have the highest tier of connectivity you offer for non-business users and I am a network engineer. You need your level 3 or advanced techs to resolve the issue. Lastly, your NOC should be picking this up for the staff to know they have degradation in the network resulting in sub-par performance for consumers.

After factory resetting and redoing all the coax cables the problem is fixed for now but this always seems to happen with Xfinity no other service I've had degrades overtime like this. This is a huge problem that seems to happen to a lot of customers.
