And very poor customer service, seeing so many complaints they should really prioritize dev & testing. This and other mesh products of theirs are only mesh in the name with such soft! I'm going to write to their CEO. Maybe this will change something  

Agreed.... It's been far too long. TP-Link needs to prioritize getting this 1.6 update out for the deco series.

  @sparta1osu I have the M9's and i dont have any network lag issue with my nintendo switch.

@TP-Link Any news regarding the new firmware or can't you read this forum due to bad connections?

  @TP-Link 

still no ETA or any update?

we need solutions. 2 years waiting for improvements. I have several TP-Link devices but without an upgrade it's hard to keep these expensive pieces of plastic running. Google Wi-Fi mesh is far superior, a 3 year old product gets firmware update from time to time and never crashes.

I agree that firmware 1.6.0 has been long in waiting, it should be released for M9+ as soon as possible. However, I disagree with the idea that "it's hard to keep these expensive pieces of plastic running". First, my M9+ units were reasonably priced, and not a single crash has been experienced by me in 2 years. My units are very stable, and that is the most important feature even if I would like to have some more router features.

Good to know this exists.  Hoping for the update to come to M9+.
