I have four P9 units. Two (kitchen, garage) are hooked up to ethernet, the other two (hall, bedroom) are via Wifi. I have the system set to Access Point so that my main router is handling DHCP duties. The main router's wifi is turned off. For the Deco P9s I have Fast Roaming and Beamforming turned on.
1) How can I tell if the powerline backhaul is working? I don't see any mention of this feature in the Android app.
2) How can I change the Deco P9s' wifi channels for 2.4 and 5.0 ghz? I want to move them away from the neighbor's channels.
3) The bedroom P9 has a clear line of sight to the hall P9, 25 feet away. But the Android app shows the bedroom P9 is getting its Signal Source from the kitchen P9, which is about 35 feet away, and blocked by two external walls, one internal wall, and a kitchen full of appliance. I'm thinking that's why if I hold my phone next to the kitchen, garage or hall P9s, it gets 240 Mbps on Speedtest.net, but next to the bedroom P9 it only gets around 90 Mbps. Is there any way to force the bedroom P9 to get its Signal Source from the hall P9 instead?
