I happened to notice that our touchscreen did some type of update yesterday. I checked the devices connected to my Xfinity Gateway this morning and I have a new device showing up as connected on the 5 GHz Wi-Fi. The only device that I have deliberately connected to my 5 GHz Wi-Fi is my MacBook Pro. All mobile devices that I have manually connected other than four cameras and a Ring doorbell are connected to the 2.5 GHz Wi-Fi. The reason I’m posting here is that I’m wondering if this new device name that is listed as BA874F72B884 is the touchscreen for the Home Security system? I’ve never seen it listed in my connected devices before. I decided to reboot my gateway and touchscreen. The device has completely disappeared from the lists of connected and not connected devices. By the way I received no notice on my iPhone or Apple Watch that a new device was connected to my network. I’m confused.
