Country Code Patch for High Sierra

[RehabMan]

Hi RehabMan, since changing to High Sierra the country code fail, but Sierra with FakePCIID kexts + appropriate country code patch works.

High Sierra requires a different country code patch than Sierra.

Solved, thanks McShmoopy.
Had installed FakePCIID_Broadcom_WiFi.kext
Install AirportBrcmFixup.kext and boot arguments: -brcmfx-country=ES -brcmfxbeta -lilubeta
et voila¡¡

@fontanero Thank you very much for posting! I see your transmit rate is at 216. But, since your connection type is 802.11ac shouldn't your transmit rate be 1300?

hello, the router is far away, but since I have cable, I do not care

What determines the region that should be matched against? I live in Iraq, although I got my Wi-Fi card from Ebay USA. I'm having troubles with me new 5Ghz AC access point...

Happy Holidays RehabMan! How the country code patch should be done in High Sierra? One more question: which method is the best to enable the BRCM94331CD WiFi in High Sierra since in my case is not working OOB?

Ah, ok. I believe that my USB settings are causing the WiFi issues (after upgrading to High Sierra the USB is messy), since the WiFi-BT combo card connects to an internal USB header. The config. plist file I’m using does not reflect the DSDT patches in the attached config_patched file that you suggest to use along with the usbinjectall.kext
