I agree with what you have said and it was only after a lot of research, that i decided to go with a mesh setup. Unfortunately, it does not work how it was supposed to.
For example, i loaded a youtube video when im in the room, with the tablet associated to the mesh unit in the room. nobody else in the entire house is using the internet at this time.
I then walked to the living room. I can see my signal dropped and my video stopped as it says no connection. I would have expected that at this time, the mesh unit would have been intelligent enough to switch me to the next nearer unit, since I am no longer having any network connection (as the signal is really low).
Ok, so i thought it needed time, so i put the tab to sleep, and left it there for 15 mins. Came back after, turn it back on, and I can still see it associated to the same unit from my room, the signal is low, and i still cant surf. I need to manually turn off my wifi, effectively disconnecting me, then turn it on again, and this time i will be connected to the nearer mesh unit.
Hence my question on how to know that my Singtel mesh is working/configured correctly. If this is how it really works, then its really disappointing. I wonder if other mesh system works the same.
