Unknown device on wireless network mac#

The upshot of this is that, if some device drops a corrupted ethernet frame into an A-MPDU aggregate, or a bad frame on the ethernet that has a corrupted header but happens to match the ethernet checksum (one in 65536 chance of this happening, but given that ethernet can carry hundreds of thousands of frames a second, this happens fairly frequently) you get a phantom device that shows up for a little bit and then goes away again. Since it's connectionless, we don't know if a wired device went away, or is just being quiet, so we keep their path table entries around for a little while after the last time we heard from them. Wired ethernet is connectionless- there's no association process- so it has to be done this way round, if you see what I mean. Weird thing is that this has been working for a year but all of a sudden it is doing this.ĭevices show as wired if they can't be attributed to an active wireless connection. All the other instances are shown in “recently online”.ĮDIT 2 : The culprit seems to be an Internet gateway device used by my solar panels (SunPower) to phone home. I rebooted my network and all except for one instance of “unnamed device” remained connected. Has anyone seen this type of behavior before ?ĮDIT : It seems like a single device is generating these multiple connections.

I did not add any new devices to my network today. They also all show up as wired connections. Eero has assigned IP addresses to all of them. All the devices show 'unknown manufacturer' and have blank hostnames.

None of them have similar MAC addresses and any MAC address lookup couldn't identify the manufacturer. As of now, at least 8 30+ new unidentified devices joined my network.
