Months of 1.2GB now only getting 80mb last 90 days.
As the title says I was getting 1.2GB download speeds and the last 2.5 months the speeds are stuck at 80mb. Getting someone (not a robot) at Comcast has been a challenge so here I am posting before I fulling move to Starlink (I have it at another property and its cheaper and amazing). Any suggestions would be great. Thanks!

Cable distribution. Kinda iffy. You got coax connector problems, plant problems/distribution problems and gateway problems. Any one of those could be your speed problem. It's not like fiber where it either works, or it does not.
I'd start here paying close attention to what you see for signal power/snr/errors when you log into your gateway both up and downstream. Look at your cabling too. https://forums.xfinity.com/conversations/your-home-network/internet-troubleshooting-tips/602dae4ac5375f08cde52ea0
If you don't want to, you can have a tech come out. If it's your house wiring, or splitter problems you pay, if it's upstream from you, then you don't.

Sometimes I find it more simplistic then that, the trains run right by my house, the vibrations on occasion will slightly unseat the Ethernet cable causing the negotiated link speed to be 100 Mbps instead of the full speed, i can visually look at the back of my gateway/router and see if the Ethernet port lights are green = full speed or Amber = 100 Mbps, in my case it’s always amber, I just reinstall the cable making sure the connector is Completely seated in the socket, if that doesn’t fix it I try a different/new cable, it’s a simple free check…

I had a somewhat similar issues a year or so ago. After a few calls and explaining what the issue really the tech did something on their end, rebooted again and magically speeds went way up. I tried to get an explanation of what they changed but got nowhere. Thankfully didn’t need them to come over.
