trouble with internet speed
Previous speeds of 960 down for years, suddenly 70-80 down.
Called support, they rolled a truck, tech ran some tests, claimed nothing out of sorts, replaced a barrel connector and then went on a rant about my modem, Motorola MB8600 being the problem. I offered to have him activate my other modem an Arris S33 which also connects at the same lower speeds. He wanted to use my phone for some reason, attempting to blame the speeds on my wireless network, I had to grab my phone back from him after I realized that he was scrolling through my phones open apps for some reason. Shady.
Regardless, I run a Ubiquiti Dream Machine Pro main switch with 6 Wireless Access Points around the property, all hard wired at 1G speeds and the tests I am referring to are coming from the UDM Pro itself which is literally one 1M cable hop away from the cable modem. My backup internet DSL from CenturyLink has remained at the same speeds for the duration of this.
I have been warned by my UDM Pro of high latency for about the last year with requests to reboot the cable modem, which itself does go offline a few times a week, long enough to trip a switchover to my backup internet DSL.
Out of curiosity I hooked a cable directly to the Xfinity pedestal at the edge of my property which resulted in the exact same speeds. There is literally nothing more that I can do and any interactions with Xfinity seem to just be someone reading a script, reboot your modem, check your cables, your wifi is your problem etc. It is beyond frustrating.
I have,
1. Ruled out the modem by testing three separate Docsis 3.1 units.
2. Ruled out the run from the pedestal through my house by testing directly at the pedestal.
3. My upstream power numbers are a little low at 38-40 and signal to noise ratio looks clean.

You are not alone. I moved into my home in 89, the subdivision was built in 82 so the main cable and pedestals are original. Everything else, coax cable from the pedestals to the home, the filter at the home connection box, the coax cable from the box to the modem, the ethernet cables (CAT6E) AND NEW COMPUTERS have been changed. The problem is when it rains the speeds decrease significantly and I pay for 800mbps but the hardline connected speed to my work laptop is only 50 mbps. When I call the 800 comcast number and report slow internet, the speech is always the same (there are faults with the signal and a restart of the modem is necessary). The pedestal is the only remaining device that is over 42 years old, and I am sick and tired of calling comcast and getting lip service from a canned script. They are to send out a specialist trained on the pedestals tomorrow, I am going to demand the [Edited: "Language"] thing be replaced. Please wish me luck, [Edited: "Inappropriate/Solicitation"] to give me a different option or competition to force comcast to fix their [Edited: "Language"] system!
Comcast, please stop all of your employees ask your customers to get your cellular service. If the internet service to our homes is garbage, why would we consider your mobile service that is secondhand service from verizon? The sales pitch is not received by the customer warmly, nor wanted!
