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!

    The Cisco DCP3939 should be your Xfinity xFi Wireless Gateway, as seen here, and may be known as their "XB3":
    The default IP address should be 10.0.0.1.

    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

    My apologies, then. Is it possible to provide a screenshot, to try to better see what you are seeing?
