Need help! Airdrop has a problem with my Hackintosh after wake up every time

[lamar8]

I bought a WiFi card BCM94360CD (including BT4.0) in recent days. It works well basically, both airdrop and handoff. But an annoying issue came.
Problem is that airdrop doesn't work every time after wake up from sleep. If I reboot the machine, it works again. Then I try to find out the reasons.
Finally, It seems I found the reason, but can't solve it. I find that the "airdrop channel" changes from 149 to 6 when it wakes up. My other MBP2018 never has no such issue because it always channel 149.

I find the WiFi channel has some relation with country code(e.g. US, CN). the strange thing is my machine doesn't show the country code. I search the Internet and can't find the same situation as me. My MBP2018 shows the code: CN， while the Hackintosh doesn't show the item "country code" at all.


So I guess if I set the card correct country code, it may work well.
I tried this solution but nothing changed.

Change Mac OS X Wireless Card Country Code

I have problem connecting to a wireless router using Mac OS X which is on channel 13. This is because there is some other router nearby which is broadcasting the US country code. The only way aroun...

sudo perl -pi -e 's|\x81\x78\x30\x6B\x10\x00\x00\x0F\x85|\x81\x78\x30\x6B\x10\x00\x00\x90\xE9|' /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortBrcm4360.kext/Contents/MacOS/AirPortBrcm4360 && sudo touch /System/Library/Extensions/

Does anyone have any advice about solving this problem? Many Thanks.

My machine:
CPU: E3 1270v3
GPU: RX 480
Motherboard: H81M-K
WIFI CARD: FV-T919 (BCM94360CD)
OS: 10.15.1

Hi, i have a Broadcom943602baed card and i also have the same problem as you in 10.15.4. The airdrop channel changed from 149(boot) to 6 after wake up from sleeping and airdrop don't work, while wi-fi network and bluetooth all work well after wake up.
However, i am also a newbee of hackintosh and can't fix it, but i managed overcome this problem by these two ways: (1)shut down wi-fi from top panel and click "turn on wi-fi" button in airdrop in finder. OR (2) simply click sleep then wake it up immediately.
Hope these be useful to you !

I had a BCM94360CD and do not have this issue, but I did notice my Firmware Version is listed as "7.77.111.1" instead of the one in your screenshot, "7.77.106.3"

Perhaps that's the difference? Maybe there's a way to flash it through the M.2 port?

Cheers

Thank you for the information. I upgrade my OS to 10.15.4, and the Firmware Version becomes "7.77.106.3" , but still it not works

Thank you! It still seems the best solution so far.

I had just upgraded to Catalina and ran into the same issue. I spent a few days of endless searching and trying lots of suggestions. Nothing worked. I figured why not try a new install using OpenCore. Everything is working well now.

Yes, I upgraded the system to Big sur using OpenCore a few days ago, and this issue has gone. I thought it was fixed by Apple in Big Sur. However, it may be the issue in Clover according to your example. Thank you.
