3x M5 here. I could have done with M9 as I run a powerline out to the shed. I bought M5 for Ethernet backhaul. The only issue is you can’t select channel at all, even for the guest network, and Wahoo bolt can only use 1 - 9.
I’m running as access point atm but will be getting a new modem to allow me to use it for routing, I’m curious about network usage monitoring.
Oddly they don’t wall mount.
