community – Cannot connect with a particular Wi-Fi with error : unsupported get ioctl on awdl0


I am making an attempt to hook up with a combined 2.4 GHz and 5 GHz Wi-Fi. When making an attempt to attach with the proper password, my Mac is asking me to kind the password once more. By checking the logs, I used to be capable of finding what was the error:

_Apple80211AWDLCompatibilityInternal: unsupported get ioctl on awdl0 for APPLE80211_IOC_CURRENT_NETWORK[103]

The primary time it occurred was random, I used to be on the web and linked to the identical Wi-Fi after which instantly I did not have entry to the web and my Mac was asking me to kind my password.

By working ifconfig, I used to be capable of see that, each, awdl0 and llw0 had been inactive (which result in Airdrop and Airplay being unusable). I used to be capable of activate awdl0 again however not llw0.

Listed below are the issues that I’ve tried thus far:

  • Overlook Wi-Fi
  • Eradicating the next recordsdata:
    sudo rm /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist 
    sudo rm /Library/Preferences/SystemConfiguration/com.apple.wifi.message-tracer.plist 
    sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist 
    sudo rm /Library/Preferences/SystemConfiguration/preferences.plist
    
  • Reset NVRAM/PRAM
  • sudo ifconfig llw0 up (not working, llw0 nonetheless inactive)
  • Restart in secure mode
  • Manually including the Wi-Fi
  • Reinstall macOS
  • Attempt one other session

None of them labored. I additionally tried offering an IP deal with manually all through my router’s interface however it did not work as effectively. Separating 2.4 GHz and 5 GHz labored however just for the two.4 GHz bandwidth. 5 GHz on my MacBook works effectively on a unique Wi-Fi.

I’ve a 13 inch MacBook Professional M1 Sonoma 14.5 (updated)

Any concepts? I wish to keep away from a manufacturing unit reset.
