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!
