Devices on Wi-Fi that Aren’t Mine
I recently moved into an apartment building and started service with Xfinity. I only own ~4 devices that should be connected to my wifi: my laptop, phone, PlayStation, and TV. No one knows the password but me. However, when I open the Xfinity app and look at the devices connected to my Gateway, there’s at LEAST 15 devices connected at any given time that I don’t recognize. When I run a troubleshoot on any of the devices, it says that all of them have a “wired connection” to my gateway. I have no devices with wired connections. It’s pretty obvious that this means my neighbors are stealing my wifi, but how do I make it so they can’t? Xfinity support says that it’s impossible for anyone to connect to my wifi without the password but that’s clearly not the case.

Connect to your gateway, IP 10.0.0.1 using browser and make sure your both frequencies have correct security settings.

I got a new modem and it shows 52 devices that aren’t connected but once we’re. Is this from a previous user? I don’t recognize any of these devices?

Xfinity modems use MoCA. It's Ethernet over coax. Your neighbors could be intentionally or unintentionally connecting to your gateway. There is no security in the MoCA version Xfinity unleashed on the public. You can turn it off with the app, but many report it turns itself back on. They're also running up your data usage, and using bandwidth, plus it's a security problem.
Try an MoCA PoE filter (point of entry filter). It blocks the higher frequency MoCA uses. If you have no MoCA devices yourself, like a coax connected cable tv box, you can screw it right to the back of your gateway. If you do have coax connected devices, it should go on the coax where your service enters your residence.
They're around $10 on Amazon, or you can order one and have it delivered to a Walmart in a day usually. You can also get one at an Xfinity store if there is one by you. Search for "MoCA PoE filter" to find one.

I have exactly the same problem exactly and I've used 415 GB of data in one month. And I as well have a TV 2 smartphones and a laptop. There's no way and it's only me. I have no other people in my home. An xfinity won't lower my bill.
