Hello,

I just purchased the Deco P9 mesh WiFi (x3) set, installed all 3 units and got them working together. Unfortunately, I suspect that the CPL backhaul is not in use, given that I get very poor speeds when on the other side of the house, right next to one of the P9 units. All 3 units have a constant white light, they all report as OK in the app. When I move the far away P9 unit a bit closer in the direction of the master unit (as far as the power cable reaches of course), the speed gets better, which proves that the units are connected over WiFi rather than CPL. I chose the P9 line especially because of the CPL backbone feature, not sure what I am missing here.

Next to the master P9 unit, I get 490 MB/s, next to the far away P9 unit, I get around 45 MB/s.

PS: My electric installation is CPL friendly, never had issues using CPL before at home

Any suggestions as of what might be going on here?

Thanks
