Wifi can’t find networks

Hello, just upgraded to monetary on my 5,2 mid 09 MacBook and the wifi cannot find one network. None even come up. I even patched up everything after it installed and still have this occurring problem. Someone help please? Stef

Hi there! Thank you for your post. This is not a GitHub related question so I’m not sure you will get much help here. I advice you to post in more general forums such as Stackoverflow.
