Planet Technology PL-501v2-US - Manual (Page 13)

The Network tab shows the powerline units that are connected to the current
computer and other powerline devices on the Network Topology, and it will also
display Mac Address of each device.
*Note* If you do not see ANY unit in the device status but the powerline device
does exist, try to unplug all devices and plug them back. Meanwhile, please
make sure the cable is the right type and working correctly. If all seems to be
correct, and you still receive nothing in the Device window, try rebooting your
computer.
Part 2: Diagnose a Network Powerline device
The Network tab shows all the other powerline units on your Network Topology.
It will represent them by MAC Address, and will also show the available
bandwidth to each unit (Units farther away from another powerline device might
have a lower Data Rate).
**Note** Only units with the same Network Key will be shown.
