I’m currently trying to use the latest installation media, released yesterday for elementary (version 5.1). Currently it’s showing no signs of support (drivers) for WiFi network adapters. Are they included in the installation media and if so what ones are compatible please?
For your wifi card to work, you must check a case during the installation of Elementary OS (this is very often the case for many LINUX distribution)
Before the installation in the window Update and other software you need check this option :
Install third-party software for graphics Wi-Fi Hardware and additional media formats
