Hi,

Was the first P9 connected to Deco M9 via wi-fi or via Ethernet cable?

Can I have a picture of the signal source strengthen on the 2^nd Deco P9?

I supposed the whole house is under the same electric meter, right?

If you put the 2^nd P9 much closer to the 1^st P9, would the PLC backhaul take effect?

Thank you very much.

Hi, If  I got it correctly, the current network topology is like this(the map would also display on the web UI-network map):

                                                             
Virgin Media superhub---M9 main--(12m)---M9 Dining hall（wifi backhaul）---M9 upstairs bedroom（wifi backhaul）

                                                  \
                                                   P9 kitchen（wifi backhaul）---(10m)--P9 Garden study office（wifi backhaul only, no PLC backhaul）

So After relocating the 1st P9 from the living room to the kitchen, the signal source of the 2nd P9 has changed to 1st P9; but the signal source is still on wireless backhaul only, no PLC backhaul;

The Previous topology is like this:

Virgin Media superhub---M9 main--（12m）---M9 Dining hall（wifi backhaul）---M9 upstairs bedroom（wifi backhaul）

                                                 \                                 \
                                              P9 living room              P9 Garden study office （wifi backhaul to M9 dining hall）

PS: If the PLC backhaul takes effect, the signal source should be like this:

Please feel free to let me know whether there is any mistake or not;

Thank you very much.

Thank you very much for the update.

I would like to follow up on your case by email and please have a check of your email box.

And In case there is something wrong with the Deco P9’s powerline backhaul feature, could you please put them into the same room and check the signal source again?
