(NULL) in Device Manager

[Wintercabin]

I name and list all devices on my network using the device manager.  I use the XR500.   There is a device called (null) and it's barely using upload per the traffic monitoring.  I have gone through all devices in my house and have no clue what this is!

 

Anyone else seen this and know what it is?   FYI - I tried turning off the private wifi option on my iPhone (heard it creates a NULL) and it didn't go away.

 

any advice is welcome

Copy the MAC address then use a mac vendor lookup site to see if that gives you an idea of what it might be

tried this but doesn't really help identifying it.   I blocked it and it still shows activity on the network monitor

[Netduma Fraser]

Does it match the MAC address of the router itself?

[Wintercabin]

nope

[Netduma Fraser]

What's the MAC address? I'll have a look, you can PM it

thanks - sent

From what I can see it's a Unicast device, most likely smart, e.g. a lightbulb, does that ring a bell? If you block it on the Device Manager some device will stop working as it should

[Wintercabin]

Hmm, we don't have smart light bulbs.  I have some RGB strips in my office but unplugged those and it still showed.  What's odd is that at the top of the hour, it came off the device list..

[Netduma Fraser]

Bizarre! If it happens again block it and you should be able to figure out what it is.

It's been blocked.  Nothing has been functioning out of the ordinary yet
