Can't connect to a specific wifi with error : unsupported get ioctl on awdl0

I'm trying to connect to a mixed 2.4Ghz and 5Ghz wifi. When trying to connect with the right password, my Mac is asking me to type the password again. By checking the logs, I was able to find what was the error:


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


The first time it happened was random, I was on the internet and connected to the same wifi and then suddenly I didn't have access to the internet and my Mac was asking me to type my password.


By running Ifconfig, I was able to see that, both, awdl0 and llw0 were inactive (which lead to Airdrop and Airplay being unusable). I was able to activate awdl0 back but not llw0


Here are the things that I have tried so far:



* Forget wifi

* Removing the following files:






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 still inactive)

* Restart in safe mode

* Manually adding the wifi






None of them worked.


I have a 13 inch MacBook Pro M1 Sonoma 14.5 (up to date)


Any ideas ? I want to avoid a factory reset.
