Official now,

I got the Wifi working on the Acer w4-821
In review it is apparent this could have been done with MX-15 ,
but MX-16 is so much more polished anyway...

After burrowing through reams of links I began to see
this system is much the same as Well's Transformer.
3740 chip and all

It has been a very long time since my first efforts,
a lot has happened in Baytrail land.
Not much of it successfully.

For anyone landing here about 3740 Baytrial Broadcom wifi,
this will probably not work, but this is what I found worked:

in MX-16 you need to boot edit GRUB the command-line
to use nomodeset option
important - keep the antiX=MLX option (why, I donot know yet)
then just copy brcmfmac43241b4-sdio.txt into /lib/firmware/brcm
then
donot modprobe as suggested elsewhere
use the MX tools "Broadcom Manager"
to unload then load the brcmfmac driver
Network Manager should squawk about finding wifi to connect.
otherwise,
you will still face further digging to fix wifi - good luck.

sound looks like it may work but needs a lot of digging,
my first effort seems to have missed the mark.
Bluetooth is hiding somewhere not visible (more SDIO lunacy)

ultimately this piece of junk may actually work,
but it will eat days of effort.

One thing I do notice different this time,
unlike under Win 8 it runs for hours without crashing (yet )

touchscreen works, and it fits cargo pants.

Maybe some of those CherryTrails might work, eventually.

At least with a working wifi the device can be hacked,
unlike some brick that needs to be spoon-fed revisions via USB.
(USB wifi dongles over dinky little one-hole devices is dodgy++,
and more often than not fail halfway through a session)

cheers
