Connectivity Drops

[narianor]

I've been having consistent disconnects every 20-30 minutes that usually last 4-5 seconds on multiple devices, [Laptop(Ethernet), Desktop(Ethernet), and Mobile Phone(Wifi)] over the past month or so. Generally it's noticeable due to using applications that drop service completely if disconnected from the internet briefly.

As far as troubleshooting goes, I've gone ahead and reinstalled Windows on the Desktop and Laptop, powercycled the XB6 gateway multiple times and have had the online support agent send refresh signals to the gateway. I've exchanged the XB6 gateway with another of the same model through my local xfinity agent and changed out the Ethernet cables going between the gateway and the ethernet capable devices. Testing out another coax cable didn't fix the issue either. Powercycling the gateway results in it being solved for a couple hours only for it to appear once again.

Just ended up giving up on this issue. I'll just live with it. Requesting to have this thread shut down.
