Back in June 2019 mjb87 reported router clients with no name and no MAC address. He/she did not report the firmware being used but did say the MAC prefix was 3A:9D:82.
I too have been seeing router clients with a blank name and blank MAC address (firmware 7.1.2).
Because I have DHCP logging enabled, I know that the MAC prefixes were aa:5e:4e and 1A:07:2B. I traced down the client device - it is running Android 10 and using the new default of a randomized MAC address.
In the screen shot above, the two blank clients are the same device, connected to different SSIDs. Each SSID is assigned to the same VLAN. One SSID is WPA2 Personal, the other is WPA2 Enterprise.
Why is the MAC address (and name) not displayed for these clients?
SSID property called “Privacy” is set to “Use randomized MAC”. That is what I was referring to earlier when I referenced the “new default of a randomized MAC address.” Sorry if this wasn’t clear.
Sorry for the late reply, private MAC range will be filtered to show in the Client List page.
The reason why the private MAC is not shown is because the info won’t able to help you to trace the client info while creating more confusion for those devices. Example : DHCP reservation won’t work for those client devices.
Feature improvement is filed and Engineering team will further review this.
Private MACs are a relatively new thing and the user interface needs to adapt. Showing nothing when the system knows something (that MAC is temporary) seems like a mistake.
That the MAC is unusual needs to be indicated somehow. Maybe an asterisk, maybe a different color, maybe bold, maybe half of the MAC displays bold, maybe a new column in the Client List. Something. Showing nothing makes it look like the system knows nothing. And, even if the MAC is temporary, the router admin may want/need a pcap trace and the temp MAC will be in that trace. Won’t it?
