Anyone have an idea what this is? 82:cc:4b:9e:d0:0d is none of my devices

This is almost certainly a device providing a randomized MAC for security/anti-tracking purposes. This is standard on Apple and many Android devices now.

Check your phones/tablets/computers/watches for this randomization feature. Apple calls it "Private Wi-Fi Address" and it is found when you navigate to Settings > Wi-Fi > [i] next to the network name.

You can always do a MAC lookup to see the vendor of the device based on the MAC itself, but in the case of the randomized ones, they generally come back as non-existant (another clue that this is likely what I said at the top):

3

All my devices broadcast their name except my watch (which is 2.4GHz) and iPhone but I checked anyway and none are using that MAC address.

Not to mention all my devices know my password. That never tried to handshake but it did take down my 5Ghz network. 2.4 worked just fine.

4

Similarly, my watch was generating a bunch of entries like this without hostnames -- it took a while for me to find it, but I looked through the settings and sure enough it had private addresses enabled. (I did figure it out, in part, by looking at the IP address).

Are you saying that a device that was attempting to connect actually took down your 5G network??

5

Yes. 5GHz was down. not loading pages.

I had to access the router from 2.4 and then while web pages were loading fine LuCI was, practically, unreachable.
When it finally loaded the log, I had another long wait to reboot it.

6

If you had a device that was truly hammering at your router, I could see it effectively causing a DoS type situation.

But you're saying that the device wasn't ever able to connect, right? If that's the case, there isn't really anything you can do about it since it's not authenticated to your network.

7

No, it never connected.
I thought it was a dos attack or pw brute force attack too.

My 2.4 is crazy low power (1mW), and 5 is 6mW (8dBm) because I try to limit range to just my apartment.
