Asus Mesh routers unstable

[DilipHK]

Hi Everyone

 

I have helped my boss set up his home network.  He lives in a 4,000 square feet apartment, in a weird long L-shape, with several thick cement walls inbetween.

 

I have set up 3  Asus RT-AC86U routers,  one in the center of the house,   and two the other sides to form the Asus Mesh Network.  He has approximately 40 network devices i'd say,  mixture of iphones, ipads, laptops, IP cameras,  alexa devices and so on.

 

Almost all his devices run on wi-fi.  Very frequently, the network goes partially dead or fully dead.  Sometimes, one of the mesh's will not work,  sometimes the entire network goes dead and only a manual reset of all devices will fix this.   I've done everything i can think of to help him resolve this.   The wi-fi signal is not weak,  it is fairly strong in all parts of the house.  Just that the network keeps going out from time to time.  He is getting so pissed at me because he has to reset his routers every other day.  

 

Any thoughts?

I don't know about mesh but how about Ethernet APs
