The AC3200 has not been available on the USA or Singapore sites since 2017.
People on this forum have been told by ASUS support that:
AiMesh is NOT going to be available for this model and yet another forum member got the reply that AiMesh IS coming soon .
In the UK 2 major suppliers list the AC3200 as end of life, one company I queried this with replied that this end of life statement is direct from ASUS.
I asked ASUS support if this end of life statement is correct , answer given was " We have no information about this "
2 other people I know have asked ASUS support the same question and again got different answers :
1) Yes this model is ceased :
2) No this model is current and will continue to be supported.
Going on experience of other ASUS devices I have doubts we will see anything more for this model , ( I hope I am proven wrong.)
I have had other high end devices that ASUS simply failed to support , the last being the top ASUS Zenfone which they dumped without any support and refused to even reply to the customers they had left stranded.
ASUS have a lot to learn about customer relations and ethical trading.
Maybe we should all change to new TriBand Lyra Voice
