WiFi crashes the system in Monterey with the Fenvi T919

[Benedict Lightning]

Hello. 
I have a Gigabyte Z490 Vision G board with a Fenvi T919 PCIe-BT/WiFi card installed. This couple worked really well in Catalina with OC up to 0.9.2, but today I've decided to do a fresh Monterey 12.6.5 install on a new SSD.
Now the WiFi is not working properly.

What I've tried so far:
 

• Enabling the option "DisableIoMapper" in the OC config makes Fenvi work, but for a short time. Networks are visible, but the system crashes in less than a minute.
• Adding Airportbrcmfixup to the Kexts folder and enabling it in config
• Adding brcmfx-delay=15000 to boot-args. This does what it says: it adds a delay to native driver loading. But after that, again, crash.
• Disabling "DisableIoMapper" in the OC config .This disables WiFi, but there has been no crash as of yet.

 

Strangely enough, the BT module is working well.

 

So...any advice?

The Fenvi T-919 works OOB without the Airportbrcmfixup.kext, you just need the kext for your Network that's all.

Make sure VT-d is disabled in the BIOS and DisableIoMapper=Yes is in the config.plist, reboot, clear/reset Nvram and you should be good to go.

The problem is gone—well, sort of.

Since I wanted all my hardware to work properly, and among other things, my motherboard has an I225-V Ethernet controller, I ran into the problem described above.
The fact is that in order to make this controller work in Monterey, its firmware needs to be reflashed with a custom one, which can be found on the Internet (and I'll not provide a link to it here). For this custom firmware to work, you need to turn on VT-d, and that's why WiFi stops working. If you try to "start" WiFi and reflashed Ethernet with VT-d enabled by adding Airportbrcmfixup or turning on DisableIoMapper in the OC config, conflicts will arise, leading to a system crash.

Therefore, at the moment I returned the native firmware of the controller, turned off VT-d, and now WiFi works as before. Since it's more preferable to use WiFi than Ethernet in my case, I decided to leave things as they are for now.

Hi all,

I finally managed to install Ventura 13.3.1 in my HP OLD rig, see below, I have the same card as you(T919), and my problem is not Wifi, but Bluetooth.

I have Monterey in the same machine, different SSD and it works fine with the USBMap done for this machine in Catalina. My supposition is that the internal USB that I think it's USB1.1 is the problem, although I have USB1.1-Injector.kext in the config. 

Any help would be appreciated.

Thanks.

USB Mapping or lack of is possibly the problem here.

As an experiment, if you have USBPort.kext, disable it and add the USBInjectAll.kext, reboot reset Nvram and see if the B/Tooth is activated/available once you reach the Desktop.

Thanks for your reply.

I have USBMap.kext, the same I use in the Monterey without any problems. I already done that test using USBInjectAll instead, but no go!

I don't know about your mainboard. But may be this is the problem when it has happened after upgrade to 13.3.1?

If as you say B/Tooth works in Monterey, then obviously something is amiss in Ventura why it's not working.

My first thought was a USB Mapping problem but you dispelled that notion as the result was the same with USBInjectAll.kext.

This maybe a bit out there so to speak but try if you can move the card to another Slot if available, mine is situated in the last Slot of the Motherboard.

Definitely is something to try, mine is in the first slot.

But one of the experiences I already done was changing the graphic card to the other slot and an USB3 expansion card to other, and Ventura stopped to boot, every USB port was dead. 

After return everything to initial position, booted again... well I know it's a bit odd but that's what happened. This problem didn't happened with the Monterey. Some kext must be interfering with bluetooth. I upload my EFI/config.plist if you wish to take a peek. And thanks for the help.

I suggest to try:

• remove all bluetooth related kexts, Fenvi T919 works OOTB without kexts since High Sierra (al least on my system)
• get latest OpenCore 0.9.2 (beta) to enable a new quirk named DisableIoMapperMapping intended to fix wifi-bluetooth-eth issues on 13.3 and newer.

To be quite honest I am not familiar with your platform to make an informed judgment, but I would say, if you're using a dedicated Graphics Card, install it in the first Slot directly below the CPU and the WIFI/Ethernet in the very last Slot.

If you're still having problems with the suggested positions I proposed, remove the USB3 expansion card (providing it will not hamper i.e Mouse or Keyboard).

I am thinking there must be a more viable method to expand the USB3 connection than using up an extra PCIe Slot. I use a NZXT USB expansion adapter that is connected to a USB Header on the Motherboard to increase USB connectivity which works very well.

Thanks all for your support. I will try next weekend.

Well, guys i just give up.

I changed the card to different slots, i remove my USB3.0 expansion card, installed the 0.9.2 version with the quirk enable, USB mapping and without mapping and... nothing.

Wifi always works and BT nickles!

Definitely the Ventura's USB handling doesn't "like" my system so i think it will never work.

For now I'm with Monterey where everything works fine, although everything else works fine in Ventura!

Thank you all for the help.

Sorry to hear you're still having B-Tooth trouble, you can try this method as a last resort.

 

Reset the Network Configuration Files.

 

To do this:

 

1. Turn the Wi-Fi off from the Wi-Fi icon in the top menu bar.

2. Open Finder, click on Go in the top-left menubar and select Go to Folder.

3. Enter the following into the text field /Library/Preferences/SystemConfiguration and click Go.

4. A Finder window should open with some files.

5. Now Select the following files.

 

    (a) com.apple.airport.preferences.plist

    (b) com.apple.network.identification.plist or com.apple.network.eapolclient.configuration.plist

    (c) com.apple.wifi.message-tracer.plist

    (d) NetworkInterfaces.plist

    (e) preferences.plist

 

6. Copy these files and save them to a safe location as a backup. This will help you to restore the Network Settings in case of any issues.

7. Now delete these files from the folder and reboot the machine, this will force Ventura to rebuild the Network Settings including (hopefully) B-Tooth configuration.

 

Good luck.

 

 

Thanks Esaf once again, but didn't work.

I also tried to mimic the port configuration that I have in Monterey and make the port which the usb is plug in, to be internal(type:255) but no way!

That is truly baffling, through every OS X version my T-919 Combo card worked OOB without any tinkering from version to version and up-grades to up-grades.

I know this may sound a bit far fetched but at this point, I would personally do a complete reinstall considering all possible options has been exhausted trying to solve the problem to no avail.

My thinking is B-Tooth works OOB in a previous OS X version so theoretically it should also work in Ventura OOB as well.

 

Finally, after update to the last OCLP 0.6.5, BT started. 

As we all suspected this was a problem with USBs, a problem that this version addressed.

So now I have a full hack working!

 

Thanks again for your support!
