How can see ALL devices (including ethernet) connected to Airport Extreme?

I am running Airport Utility 6.3. I can see the list of WIRELESS clients connected. I can't see anywhere in the utility where I can see WIRED/ETHERNET clients connected.

Other posts on this site refer to an Advanced Settings Tab on Airport Utility 6.x. or else Manual Setup. I don't see this anywhere in the GUI. Under the Network tab, you can reserve static IPs, but that's not what I want, I want to see which WIRED (not just wireless) devices are actually connected. I'm trying to troubleshoot an issue with my DirecTV box which doesn't seem to be connecting even though I have reserved an IP for its MAC address. Yes, I can ping the IP, but the point is if I want to set it to DHCP, I wouldn't know the IP, and it would be nice to just see what all the devices are.

Solution 1:

There's a great shell command that scans your network on all interfaces that are connected.

The command is arp -a.

Solution 2:

iNet

iNet will scan your network for all connected devices and show you a list of devices with their hostnames and IP addresses. It also has a dedicated mode for AirPort routers showing devices connected and relevant information about each one.
