Unknown wireless client on private LAN

[mlg321]

I just discovered an unknown client on my LAN. I don't recognize the name or the device IP address. The MAC address is coming back as "IEEE REGISTRATION AUTHORITY". WTH?

Start turning off clients and see what pops up...

I can identify the other 5 clients on this AirPort. No idea what this is.

jailbroken?

If your Airport is running WPA2 (which is does by default), it might have caught a private MAC address caused by MAC Randomization as per iOS8 and later when searching for the AP...

See if it ages out... if it's persistent, then you have something wired on your network...

Simple question that may shed some light. Are you a satellite TV subscriber aka Direct TV, Dish etc.? If so it's probably using a satellite modem connected to your internet modem/router. I see DTV devices on mine as each box has a media server and registers on a separate ip address. Freaked me out too

You might try blocking the MAC address. You will know if it is one of your devices.

Hotwire TV and Internet but everything is hard wired.

Thanks for that suggestion. Just did it.

Not familiar with that set up (Hotwire). My DTV Genie satellites use wireless to connect to the main DVR, although that and the dish itself is connected through lan.
