WiFi module not working on macos Catalina?

Question

WiFi

Today, wifi fell off on all computers in the office on macos Catalina systems. On other systems and the version everything works fine. I will clarify that the wifi module itself does not work, it does not turn on stupidly. Do you have this problem on Catalina?

Answer 1

Try deleting all settings from the /Library/Preferences/SystemConfiguration/ folder and reboot (make a backup just in case). Or play around with MTU.
