... My Z490 Vision D, however, has the problem. Its WiFi does not work, but its Ethernet ports continue to work. I will troubleshoot on the Z490 Vision D. I have already extracted all the kexts from 13.2 and 13.3. Next, I need to compare the right files. Interim update: Broadcom firmware...

Nice one! Watching this closely.

These WiFi or network problems did not occur on my system after the update. I use a BCM943602CDP.

Have you Apple VT-D enabled and working though? Only seems to be in issue when that is enabled.

AppleVTD is active and working fine with dropping original DMAR table and loading a modified one. I225-V and AQC107 are also working correctly.

The Fenvi FV-T919 in my Z390 Designare is also working properly with Ventura 13.3 and AppleVTD. Screenshot shows the Firmware Version. Not sure if this makes any difference, but what is your firmware version?

It‘s the same as yours, but my modified DMAR table has always been shorter than others that I've seen, and I'm on BIOS version F21.

This one causes Z490 Vision D to reboot at the last stage of booting macOS.

Yes, same issue for me.

Can you share your config? Wonder what if you have a different table code being dropped in the DMAR -delete section.
