I'm trying to connect to a mixed 2.4 GHz and 5 GHz Wi-Fi. 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
The first time it happened was random, I was on the internet and connected to the same Wi-Fi 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 Wi-Fi - 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 Wi-Fi - Reinstall macOS - Try another session None of them worked. I also tried providing an IP address manually throughout my router's interface but it didn't work as well. Separating 2.4 GHz and 5 GHz worked but only for the 2.4 GHz bandwidth. 5 GHz on my MacBook works well on a different Wi-Fi. I have a 13 inch MacBook Pro M1 Sonoma 14.5 (up to date) Any ideas? I want to avoid a factory reset.
