Guest Mode Wifi List in Airport Extreme

Apple designed their routers for ease of use. ie network admins.. stay clear.

If you use Mojave or maybe even Catalina on the iMac then you can download and install by secret dark arts the rather ancient Airport Utility 5.6.1 Or it runs on windows OS.. at least from 7-10. I have it working on Mojave without issues except the computer cannot sleep.

Using this you will have access to the LOG.. I know.. phenomenal isn't it.

I have the Time Capsule as client on the network.. but if you have it as main router.. which you must for guest to work then the DHCP table should list the clients on the network, whether, ethernet or wireless.

I borrowed this screenshot from old post .. and Bob Timmons response.

What I am not sure is how it will handle client on second vlan.

I hope your iMac can at least take a few naps during the day.

I am one who needs a nap now.. getting old.

Yes,, just turn off the old airport utility.. no problem.

I just tried it for my own testing purpose.. and it worked fine.

I setup a Gen5 AirPort Extreme.. double NAT to my main router with both main wifi to which I connected the computer and my iPhone to the guest wifi.. and both show up.

Then using the old utility I can see both wireless and DHCP Clients.

But I also found the v6 airport utility does show both wifi and guest wifi clients.

The problem is the guest clients don't have a lot of info so you will need to track back from MAC address which clients you have.

If you put the mouse pointer over the MAC address (or name or IP are also possible) a popup with some more info appears.

Unfortunately there is nothing here to indicate it is connected to guest.

It is rather the absence of IP address in the main network. Whereas the main computer shows IP as expected in the main DHCP range.

The old utility shows the guest wireless is using 172.16.42.2 which is more useful.

Fing could not find the guest client other than computer it is running from. Even when I joined it to the guest wifi. This is correct because the guest network should keep each client isolated from others.

Using ping on the computer's terminal gave same no response.

What device are you using to open airport utility?

I have used Fing on iOS and recently installed it also on Mac running Mojave.. works very well.

The guest network exists on a different vlan to main network.. and so that might be an issue.

I will give it a go and report back.

FYI .. Just verified that it also runs on Windows 11.
