I newly purchased x20 deco. I have got few questions , please answer all of them.

Q- The version the Deco x20 came with is V3.8 (IN). , my location is India.   I am unable to find the Deco x20 V3.8 version firmware page anywhere on tp link website. I request you to please provide the link where I could check and match with the website the latest firmware version for Deco x20 V3.8 Indian unit.  

Where can I see the beta firmware version for my above deco version model ?        please provide links for both beta and stable version on tp link website, for my above mentioned deco x20 v3.8.

Q- I am provided with ISP router by my ISP and he told me he can not enable bridge mode on the isp router so I have to enable "Access Point" mode on deco to avoid double nat but I have not set up my decos yet as I am still trying to convince ISP to convert the isp router to bridge mode.

     I want to know that in "Access Mode" of Decox20,  do features like  "Beamforming, Device Isolation, MU-MIMO, OFDMA , 1024-QAM, BSS COLOR"  work ?

    if not , which features do not work in "Access Point" mode ? 

Thanks
