• Wi-Fi works on as many device models as possible (Intel Wi-Fi, Broadcom, etc.)*
• Boot and install with UEFI
• Boot and install with legacy BIOS

Known Issues

These are known issues with ISOs and/or the current installer.

• Some Broadcom devices will not have Wi-Fi in the live session until the "Install third-party software" box is checked. This is because the drivers are proprietary.
• Choosing a non-Latin language in the installer for "Try elementary OS" means you will not get a Latin keyboard layout in the live session, which can be problematic for typing things like usernames or Wi-Fi passwords. You can add a Latin layout in System Settings → Keyboard. This is a known issue with Ubiquity since 18.04.
