Many many thanks for updating and all Your trying and working!! 👍👍👍

 

What I can say about it:

 

At my HP Notebooks (Envy 13, 6th Gen. Intel-CPUs) Pin-Masking worked when macOS activated WIFI.

But mostly device can't get activated when pin-masked.

 

At a Lenovo Yoga card works without issues.

51/53/55 are tied together to ground so probably device / manufacture specific key functions

54- is usb_otg_oc# (this looks to be USB on control) 3.3v input signal from motherboard to socket turns usb off

56- is w_disable#  (this looks like wlan control) 3.3v input signal from motherboard to socket turns wlan off

Hi everyone, just re-purchased the correct 0VW3T model and everything works now, even until now i'm using AirPortBrcmNIC driver, but the wifi sometimes disconnect from 5Ghz to 2.4 Ghz, because i broke the NGFF antenna connector, but it's ok though, shutdown, sleep, wake restart OK, wifi still works, Airdrop, handoff, but sometimes DW1820A wont connect to Instant Hotspot, cheers.

 

also yesterday i watched movie for 4 Hours and no sudden freeze, kernel panic, or cpu usage increase.

 

P.S : i used the pin mask fix from @DalianSky WORKS Great for me, using Acer swift 3 notebook 😂
