Last time I had to use their services I wrapped their modem/router that they forced me to use in a roll of aluminum foil and ran one short ethernet cable out to use my own router with whatever I want. Blocked all their public WiFi you can't turn off and roasted that thing. I was genuinely surprised that it still worked when I gave it back.

This is the way
Fun fact: I have my device in airplane mode 90% of the time and only use WiFi. My device ID/name is "Unknown device" specifically so it looks like random or no good. I also use randomized Mac addresses.
I'm free of xfinity/Comcast, but for anyone else I know who uses it, I freely offer my professional IT tips to change DNS, recommend modem/gateway, etc.
If anyone didn't already know, this isn't anything new. It's basically just WiGLE but not public level, and is using that to track devices coming and going.
You don't need Xfinity WiFi to do this. Everything you have with a BT or WiFi antenna is already out there and everyone can see it. It's logged and recorded. Can literally see my neighbour's got two iPhones moving around right now and I didn't even get out of bed. Oh, they also have a JBL Encore Essential... That explains something that happened last week.
