Hello all,

I have a question regarding my home setup. I have 3 deco m5 set up in my home (brick concrete walls) 3 storeys. 
I have main deco connected to the router via powerline next to my PC in my bedroom so that I have the best latency when playing game. 
Second deco is in the living room for my other devices like ipad and laptops. This connect to the main deco and the signal is 2/3 bar. Speed test is ok i get around 40mbps in my 50 up down plan. 
Third deco is the problem. I placed it in level 2 of the house and the signal is only 1/3 when connected to main deco (downstairs) and download upload speed is only 10-15mbps. I tried connecting it to another powerline hoping it would connect to the main deco with ethernet. But it cant work. When I see the status, its still connected as wifi 1/3 signal. 
 

i tried in AP mode and can see the connection changed from wifi to ethernet but the speed drops a lot (3-10mbps max)

looking at my problem, is it better to have router as access points rather than mesh network? I cant have my deco to specifically connect to other deco with better signal other than main deco..

thanks in advace and pardon my bad english..
