Deleted WiFi as an interface and I can’t get it back
I accidentally deleted the wifi as an interface from the network settings in an attempt to get my wifi service to be working. But now I cannot add it back. Could you please let me know how to configure this ASAP?? Without internet my MacBook is useless. I am a university student so I need internet to finish my assignments and research papers.
MacBook Air 13″, macOS 10.15
