Note Only units with the same Network Password will be shown, (Password
case sensitive).
Note
If a unit shows MAC Address of all 0's, this unit might not have a solid
connection, or might not connect at all.
If there are units in the home network, but nothing displays in this
Note
Network scan, try to unplug all devices, and plug them back (Only do
this with the units that you do not view in the network screen, you don't
have to do this with all units.)
If the problem persists, try to move the unit closer to this current unit (adjacent plugs
on the same wall socket is most preferable). If the problem still persists and that unit
is still not shown on the network, then the unit might be defective, please contact
technical support. Otherwise if you view the unit working, distance might be the only
issue.
