Why is a New Device Connected to my Wifi named "Arris TG1682G"? I have password protect on and when I look at the device details it shows this is an actual router. I do not have wifi extenders, did not authorize the device to connect, and it comes with a "MAC" address.....what is this and why is it able to connect if I have a password protecting my home network?
A recent firmware / advanced security update, so now you see it.
To confirm that it's yours, see if the MAC address is the same on your 1682.
