but worry after firmware change, wifi speed drop
because merlin is not design for AC18

Bro, 3-500mpbs You mean ac18 stock or merlin ?

my ac18 stock firmware is "v15.03.3.11_multi"
tenda webpage do'n have this firmware download
only provide
V15.03.05.05_EN , V15.03.3.10_EN
do'n know this 2 firmware can use in unifi or not?

then flash to merlin how to roll back to stock firmware ?

then how to download the ac18 unifi firmware flash back ?
i try google "v15.03.3.11_multi" and cannot get it

thanks

i buy from lazada last week, ookas RM289.66

Finally I flash to merlin x7.9 software center and webshell working, I am no more use the IPTV function how I set port 4 to LAN ? Now I am use Unifi-Home mode

good news, my home upgrade to 800mbps
no sms no email, restart router speed test then upgrade 800mpbs

Yup This is PC Cable Speed

my iphone 7 plus 5Ghz max is 350 down & 200 up
this is normal ?

wow, this ac18 is very stable
since upgrade to 800 until now not disconnect yet
still same IP address

i think the 800mb is only for malaysia and singapore local network
not for international network ....
i try speedtest other country datacenter all under 150mbps ...
