Unknown device connected to my wifi
I have Xfinity wifi and it is password protected. I changed the name and password, and had to reconnect everything, my own phone included. But it shows that an ipad and unknown device are still connected. The unknown device is cisco dpc3939. I'm not too tech savvy, so if anyone could please help me figure it out!! Thanks so much in advance!

My xfinity app says its cisco3941t, so this other thing is cisco3939 and im not sure how to tell what it is. Also, this may or may not be relevant, but when it was super quiet, there was a weird staticky, low hum/low buzzing sound coming from my gateway thingy
