I am getting regular drops of upstream packets which is apparent as all devices will suddenly lose all upstream packets while downstream appears to stay ok temporarily, followed by full loss of connection. This is most noticeable while playing games as they will send downstream data to me for a while before disconnecting and services such as discord will let me hear but not speak during this time for a moment as well.
My modem settings look mostly ok, the upstream power is slightly high by my understanding but it has always been around this value. I suspect an issue exists with the local node rather than an issue with cabling or modem inside the apartment as I have confirmed there are no splitters and the cable is not corroded.

I should add that I have tried the following things already
- Removing a splitter that was supplying coax to multiple places in the apartment and replacing it with a coax coupler
- Removing a coax coupler and putting the modem directly on the cable into the apartment
- Fully factory resetting the modem
- Fully replacing the modem with a new modem
This issue happens 1-3 times a day for about 5-10 minutes at a time. No outage is reported in most cases on the Xfinity App.

Additionally I see consistent packet loss via PingPlotter trace routes to Atlanta based nodes.
