@David-TP I first installed the Aug 2021 first beta version and had lot of instabilities and connectivity issues. Then after a full reset of my 5 unities (backhaul system) M5 decos and a full setup again the network was stable and working fine. Then now I installed the March 2022 version and had connections issues (could not connect to the network) using my Iphone and Samsung Galaxy S21. Besides that network wifi speed was capped somehow in 70 mbps and I could not reach higher speeds unless the deco was rebooted. Had to roll back to August 2021 version and it is working fine again.

Can I have more details about the instability and connectivity issues on the third version of 1.6.0?
If possible, it would be highly appreciated if you could send an email to support.forum@tp-link.com and let us what exactly happened after updating to 1.6.0 beta?
Best regards.

@Dekel Do you have it in router or access point mode? In case access point: might just be the limit I refered to in my earlier posts.

@Bobus not sure what will be the benefit, I have attacked a speedtest from my desktop computer as well. you can see that I get higher speeds from my desktop, however, the main deco is unable to get more that 500.
if I had any terminal access to the main deco I would have run some speed tests other than speedtest.net.
