Planet Networking & Communication PL-702 User Manual page 18

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.
Note
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: Detect the Network Powerline device
The Main tab shows all the other Powerline units on your home network. 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). If you add or remove units from your home network, click the "Scan" button to
re-scan the network, and refresh with any changes.
