Wifi interface completely gone after catalina update on 2015 MBP

After upgrading my early 2015 MBP from mojave to catalina, the wifi interface disappeared from the system.

I don't see it anymore in the list and can't add it. Even in recovery mode, network utility doesn't show it in the drop down.

System information says

  Software Versions:
  CoreWLAN: 13.0 (null)
  CoreWLANKit:  13.0 (null)
  Menu Extra:   13.0 (null)
  System Information:   12.0 (null
  IO80211 Family:   12.0 (null)
  Diagnostics:  1.0 (null)
  AirPort Utility:

This person on stackexchange has the same problem https://apple.stackexchange.com/questions/372025/missing-wifi-interface-after-upgrade-to-catalina?newreg=1904677ef3d840f0a87b73a2cd7bd342

Is this a known problem that's going to be fixed? I don't want to downgrade to mojave, restore backups and everything and then reupgrade again...

Me too, the same error on my Mid 2014 MBP. I google how to fix it but it seem no way to do it. Apple doesn't have any reply to us. :(

I'm using ThunderBolt -> Ethernet at the moment :(. I hope Apple will apply new fix for this error soon.

I was tried but cannot make it work again. I think Catalina forgot driver software for specific chip. I'm still waiting for new update from Apple.

Yes, I tried everything.

It's a MacBook Pro 15" Mid-2014 – interestingly, I have no problem on a 13" Mid-2014 with the same Wi-Fi hardware but a newer firmware version...

Even after updating to 10.15.1, this issue still persists. I wonder if there will ever be a fix for this, or should we all just use mojave. This is really frustrating.

Has anyone found a solution to this? Is there any expectation that 10.15.2 might include a fix? My MacBook pro late-2013 wifi interface is simply missing after upgrade to Catalina.
