M9plus / P9 mesh configuration question
I have an existing M9plus 3 node mesh that works well except for weak signal in an outbuilding. I'm planning on adding P9's to the mesh to get powerline backhaul to the outbuilding to improve performance. I intend to keep an M9 as the main unit with Ethernet connection to one of the P9's. Is this the best way to set this up? or should the P9 be the main unit? Unfortunately there is no way to link the P9's via Ethernet.
