All

Thank you thus far for all the help in answering my questions. The more I'm learning the more I think I can put together a robust network. Currently every device in the house is via Wi-fi. This is what led me to the M9+. However, I'm starting to think of other setups and curious if this can work.

I have (3) rooms that I would like to wire via ethernet (if possible). I just can't do it direct to main router because of distance. Each room has a desktop and a gaming system (ie PS4). Can I run a powerline (single port) in each room connected to an ethernet switch so that I can run cables to both the desktops and gaming systems? Any issues with this setup or degradation of bandwidth beyond expected with that many devices (not sure if this is considred too many switches or powerline devices)?  My thought is if I can move more of our data hungry devices to wired, then the better. We have high speed Internet. 

Can I do this setup? Any changes you would recommend? FYI...I'm not a network tech so probably would just go with unmanaged switches.

Main Setup: Cable Modem > Deco M9+ > TP Switch > TP Powerline

Bedroom 1: TP Powerline > TP Switch > Desktop and Gaming System

Bedroom 2: Same as above

Bedroom 3: Same as above

** The remaining (2) Deco M9+ devices will be placed throughout the house for the Wi-fi mesh

All in all, the entire setup would be about (4) TP Swithes and (4) TP Powerline devices.

All other devices would just be wi-fi (ie phones, Alexa, Roku TV, Ipads)

Thank you so much!

Thanks!
