Hi

I have an M9 Plus setup and a 350mbps connection, when i run the speed test from the Deco app it shows at 350, but via wired and wireless devices the results sit between 100 and 112mbps.

I recently upgraded my connection from 110mbps to 350mbps but the speed hasn't changed. 

I'm assuming something in my setup is sub optimal which is why I'm losing all that speed. 

My setup is below, the main deco is in router mode. Deco 2 & 3 are wireless, with a PC and a Switch on a wired connection to Deco 2.

Apologies if this is lacking info, please let me know what other info i should provide.

Any help appreciated.

Thanks 

Chris
