Netgear PLP1000 PowerLINE

Hi,

I would like to know how to use the CPL on 3 phases installation. 

My house is wired with 3 phases + Neutral + earth.

I suppose that if the box connected to the router is not on the same phase as the box connected to my pc the synchronization between both will not work.

If you have any idea thanks to help me

Regards
