High Packet Loss (About once an hour)

I have had high packet loss for about the last month or so now it all started shortly after I upgraded to the Gigabit X2 Plan.

This packet loss happens to the entire network (WiFi/hard wired) and will cause disconnects to all services on my network.

I have the following equipment.

Router: GT-AX11000 Pro

Modem: Nighthawk CM3000

I have tried the following at home fixes.

Replaced Coax Cable from wall to Modem

Replaced Ethernet from Modem to Router

Replaced Ethernet from Router to PC

Updated Firmware on Router and Modem

Restarted Router/Modem multiple times

Some additional Information, this packet/disconnect loss occurs while doing any activity on the network, (streaming, online games, school/work activities). The time of the day does not matter as it seems to be randomly every hour or so, and it only lasts a minute or two and then internet connectivity is restored.

Hey @ColtonT, 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 connectivity issues. I would be more than happy to offer my assistance looking into this further for you. Have you tried to connect directly to the cable modem to limit any other devices within the home that may be causing issues?

I posted about this issue a few months ago (https://forums.xfinity.com/conversations/your-home-network/high-packet-loss-about-once-an-hour/67fda75789747f592316f264?commentId=67fdacb6b6119e1ed9f311d9) however it has not been resolved and only gotten worse.

I experience random disconnects and interruptions to my service with no noticeable reason why on my end. No indications on my devices (outside of disconnecting/buffering of videos) I've even attempted to go into the log's of my devices around the time of disconnects and see nothing out of the ordinary from what I can tell.

To add further this all started when I upgraded my plan. I previously had 1gb plan with no issues, once i upgraded to the 2gb plan I've had nothing but issues and problems with the service.

I have the following equipment.

Router: GT-AX11000 Pro

Modem: Nighthawk CM3000
