Thank you for understanding @RadxaYuntian
Actually before i came to this topic, I tried to install Manjaro first and discussed about the problem with in WIFI on Manjaro topic which you know about, because i had conversation with yourself and @spikerguy . We did a bit of investigation and i found myself here with @SKRSKR question / Topic. Which we ended up here.
So far;
I did install Manjaro > wifi didnt work.
Then i moved on to official releases
Tried Official Ubuntu without involving desktop environment > didnt work
Then I was here with Debian, and your help (which i highly appreciate, you are big help !! )
I will send an email about it, and hope i can return / replace my unit.
Thank you again,
