Just a couple things to check regarding the non-working WiFi.
1) Is the "Wireless LAN" set to enabled in the BIOS (under Configuration)?
2) Is WiFi turned on in macOS System Preferences?

1. Yes, it's worth it. 2. After, the error (which was in the photo) is worth as well as you have in the photo. What else could this be about? Can the fee be laid for the region? If there was a White List, the map would not be defined at all?

I was unlucky....
I am on Mojave (was reading someone elses post about how their trackpad started working when they downgraded). I should've mentioned that. If you are too I'd be happy to send you my EFI and we can compare /L/E. I believe I pretty much ripped all non-stock kext out of /S/L/E and /L/E and just put them all in EFI/C/...kexts.

I figure this might make it easier for us to compare kexts... it will generate two files listing all files or dirs and their md5 hashes so we can tell if we have different versions of a kext.

Bash:
cd /System/Library/Extensions && sudo perl -e 'use Digest::MD5 qw(md5 md5_hex md5_base64); use FileHandle; $ctx = Digest::MD5->new; foreach (@ARGV) { if (-f $_) { $fh = FileHandle->new("$_", "r"); $ctx->addfile($fh); $md5 = $ctx->hexdigest; } else { $md5 = `find \"$_\" -type f -exec md5 \{\} \\; \| sort -k 2 | md5 \|cut -d\" \" -f1`; } printf "%s %04o %s\n", $_, (stat)[2] & 07777, $md5 }' * > ~/Desktop/sys_lib_ext.txt
Then again for /Library/Extensions
Bash:
cd /Library/Extensions && sudo perl -e 'use Digest::MD5 qw(md5 md5_hex md5_base64); use FileHandle; $ctx = Digest::MD5->new; foreach (@ARGV) { if (-f $_) { $fh = FileHandle->new("$_", "r"); $ctx->addfile($fh); $md5 = $ctx->hexdigest; } else { $md5 = `find \"$_\" -type f -exec md5 \{\} \\; \| sort -k 2 | md5 \|cut -d\" \" -f1`; } printf "%s %04o %s\n", $_, (stat)[2] & 07777, $md5 }' * > ~/Desktop/lib_ext.txt

I think there's a problem with the card. Arranged the return of the goods. The problem is that not in the vindows does not see the network and in the Linux too. Is there anyone who's tried other cards? P.S. trackpad doesn't work either.
Sorry for my English.

@4mit do you have the HDMI AUDIO output working on your pc? When I connect to my tv with HDMI the quality video is perfect but the audio comes from the pc instead of the tv and I can't change that. How can I fix that?

@Patrick545 I did not have a HDMI audio device to test, so i don't know.
I can verify it by tomorrow and post a note on status and possible fixes.
