How do I reset my network if I don't have a SystemConfiguration folder?

I'm currently having a lot of issues with my network, disconnecting often, drive not syncing, sometimes not finding 5GHz networks, certificate approval requests etc, so I wanted to completely reset all my network settings. I've found three ways to do this:

  1. Removing wifi in settings by pressing the minus. This does absolutely nothing I don't even need to reenter my password or anything.
  2. Removing all the saved networks from the list. After I press OK and reopen the window all the networks are back in the same spot.
  3. Removing some files in the SystemConfiguration folder. When I go to ~/Library/Preferences I don't see the folder. I've tried just adding the folder myself and rebooting to see if any files will appear but they don't.

How do I fix this? I'm on a 2012 MacBook Pro on catalina 10.15.7


The SystemConfiguration folder is in the top (root) level Library folder (/Library/Preferences/SystemConfiguration), not in the User Library folder (~/Library/Preferences/SystemConfiguration).

You may want to be careful about which files you delete, as that may have consequences. Make sure you have a backup, and can access the drive from an external, if needs be.
