Does manually loading the kext after booting into the system give you the same result?

@blackberry4311 can you upload your pcie info with Hackintool? like this:

[blackberry4311]

@williambj1 I got above log when manual load the kext, and it gives me the same result
@zxystd here you are

Another thing: I success loaded this kext and connect wifi 2 days ago.

[zxystd]

same card and same driver? now it shows unknown adapter type? @blackberry4311

[blackberry4311]

yes, it worked 2 days ago, I change nothing and it show the log like I uploaded yesterday.

subdevice id is 0x0000, so weird, that should not work. do you have linux? can you check if the card can work on linux now?
I will compile a kext which will output more logs what I needed to you soon.

[blackberry4311]

I don't have linux currently but I can install it for further checking.Is Ubuntu latest version ok?

[williambj1]

@blackberry4311 A Ubuntu 20 Live USB would be enough.

[blackberry4311]

work well on ubuntu 20

Wifi back and working like charm, after I'm boot to Ubuntu,

Sub Device change like in this image

Hmm, I don't know the reason why but let me try to make some tests on this scenario first.

Found out the issue, this happened only when wifi card not using for a long time, somehow mobo auto power off this card. With cool shutdown and startup, the wifi back and work as normal, so I think we can close this issue here.

Thank you all for all support. I really appreciated
