I decided today to give a shot to the beta firmware as I was very annoyed how my v4 router was selecting its band. I did the installation using a laptop and a network cable. I backed up my settings, flashed the new firmware, restored my personal settings (they worked, so they are compatible between the stable and beta firmare).

The router is very stable as I set it to use the band with the best signal.

I am very satisfied now, thank you TP-Link!!!

For those who are sceptical, give it a shot! It's been several months since this firmware was released and I see no reports about serios issues with it.

@actunderdc 

that's good.

i can confirm the nice experience with my MR200 v4 router, the ability to choose and "fix in place" a given band is somewhat a lifesaver and something one can never do without hence.

Unfortunately, it's a bit disappointing that we have to deal with rather old "firmware builds" in order to being able to use such feature: i cannot understand why TP-LINK does not publish their latest builds integrating those with the band selection feature... Should not be anything "invasive", nor disruptive in doing so.

Why am i forced to forfeit a - say - cool MESH wifi implementation in order to being able to choose a network band to connect to?

C'mon, TP LINK - go the extra mile
