Home Networking

Can you see if the device actually got an IP address?

Depending on how your device and it's reporting works it's possible that it's just reporting that someone tried to connect to your wifi network (didn't know the password so didn't get authorized).

If you don't want people to be able to even see/connect to your wifi - hide your SSID (stop publishing it). I do this on my IoT and Camera networks. They don't publish their names until I need to add a device, then I turn on broadcasting, add the device, after it's added I can turn off the publish again.

Oddly enough, I had this same thing happen earlier tonight. I’m currently in the middle of moving and have an old router setup as a holdover. I didn’t set up any encryption in the meantime, as I didn’t feel it was warranted because of how momentary it would run.

All the same, I had a device named “Bethany-s-s22” on my past connections list. A quick Google search showed that it was just a Galaxy S22; comparatively, it looks like the device that connected to yours was a Galaxy S20, if it follows the same default naming convention. That said, I definitely put up a quick password to prevent that happening again.
