This article shows you how to get Wi-Fi drivers installed easily with one command line and a few clicks.
USB Backup
Make sure you have a USB stick ready with drivers and software from the IT Tools Teams page. If not, go here: IT Tools | IT | Microsoft Teams. You must have a USB drive the size of 128GB or larger to fit all files from the Teams group. Otherwise, you need a size of 16GB or larger just for the drivers, etc.
The Process
When the laptop you are deploying goes into the beginning of Autopilot, hit SHIFT+FN+F10 for laptops or SHIFT+F10 for desktops to access the command prompt.
Type Explorer and hit enter. This will bring up File Explorer.
Navigate to your flash drive, your Wi-Fi drivers installer, and double click the file you want to install.
Follow the prompts and continue your autopilot process by connecting to Wi-Fi.
