I just received this notification “A device named ARRIS Arris device just connected to your home network for the first time. “ This is not a device connected by anyone in my household. Suspicious? How can I block it.
My Arris devices in my xFi are my X1 set-top-boxes; I don't recommend blocking them!
Thank you, I am mostly concerned with it stating they connected for the first time at 3:27A & 3:28A while everyone was sleeping. I could not see where a “New Device” accessed my network at that time. As of now I changed my WiFi password to be safe, but thought I would ask why this may have happened.
If the set-top-box reboots overnight to update its firmware, xFi might see it as a disconnect/connect.
There could be other reaseons.
