i had many unstable issues on 1.5.2

and we downgraded back to 1.5.1

i am using test FW of 1.5.2 look stable for a while 

1.5.3 i have not tested yat need to look what are the changes 

  @shaylami 

after that whole mess of upgrade from 51 to 52, I ultimately downgraded to firmware 50 since that's what was available on the website. And all my problems went away.

I'm not sure where to get a hold of 51, or I probably would've rolled back to that.

But firmware 52 was a nightmare. I really don't understand why it took so long to get fixed when so many people experienced the problem.

Until this issue, I actually trusted TPLink. I have all my light switches and dimmers, managed switch, and decos. Not that I don't expect there to be problems, but a problem as big as this should've been fixed right away.

Hi,

I had the same issue with my smart home started to see in Home Assistants devices that disconnected period of times 

issue with connecting and moving between units

also the communication between units was so bad, i found the version in TP link website but any why if you rollback to 50 this is just fine 

i will try to do some testing on the new FW that was relesed i will update the thread here if its ok to upgrade
