I had tried once building something like this mesh - a router with several wifi range extenders sold separately. In my case it was a setup in the apartment with lots of metal in concrete panels, so wireless reception is awful (50-100% signal loss after a single wall). Well it didn't work at all - REs started and worked ok and I did see high WiFi signal, but throughput was horrible - very low speed and regular pauses when no traffic at all was passing through REs. Settings, RE positioning, channels or bands didn't matter.
In the end I just used wired network with access points, more expensive but at least it works. I suggest that all these mesh kits should be bought only when return option is available because they may not work in some cases.
