This is a bug that tp-link seems to have with all their hardware, i have had M5 and P9 and both systems will when roaming to a different Deco show at random times 'Unavailable for current firmware'....

@timp78 , how is your beta working , also seeing reboots.. (getting a bit worried now..).. thx..

@wcg , wauw.. that seems a lot.. my network is critical here, i actually upgrade to the Beta version because I had one of my satelites on random times going into red blinking error. I have not seen...

@timp78 , did you upgrade to the Beta version that was shared in this post ?

@timp78 , you can access it with: http://tplinkdeco.net/webpages/index.html

@wcg , ate you on router or ap mode . And after how often do you have these reboots.. been pretty stable for me so far?
