  3. If none of above works, go to https://github.com/chris1111/Wireless-USB-Adapter and download the Wireless USB Adapter. I had problems of airport stability and connection since the ultimates updates of High Sierra on my MacBook Air Early 2014. I have got an Edimax USB key and wanted to make it recognized by my system 10.15.6… All of a sudden the Airport get connected and is working perfectly!
