ASUS RT-AC68U Mystery MAC address

[mjweber54]

I have an ASUS RT-AC68U. Randomly looking thru my Client List, and I can't identify this client: 9E:0E:1B:16:4E:A5. Can anyone help?

It's been connected for 290 hours so I'd say it's likely some sort of IoT device or a wireless repeater.

Can I just disconnect this? I have a network extender, but that's not the correct MAC ID

You can't "disconnect" it but you could block it's internet access.

I have a network extender, but that's not the correct MAC ID

Many extenders spoof their MAC addresses. If you compare the spoofed address to the one printed on the device you'll often see that they're very similar with only a couple of digits changed. What extender do you have?

Samsung 4G LTE Network Extender - Model SLS-BU10B. Got from Verizon in 2018. We live in a rural area and nearest Verizon tower is approx 3 miles away. Keeps our cell phones connected at home.

It's MAC is

20:DB:AB:20:B3:F8

and I see it in the Client List as a wired connected device
Just can't figure out what else has been connected for 290 hours (approx 11 days).

OK so not the extender then. It is now common practice for Wi-Fi laptops and phones to use "private" MAC addresses, which are essentially randomly generated. How many things do you have (including smart TVs, etc.) that support 5GHz. Probably easiest to go around powering them off one at a time until you find the culprit. It's signal strength is strong so it must be nearby.

Sound like mobile device with randomized MAC. Near the router indeed.
