We recommend using NetworkManager to manage network connections. If you choose to connect to Wi-Fi while using the live installer image, your Wi-Fi settings will be added to your system during the installation process.
NetworkManager provides three simple methods for configuring Wi-Fi.
Click anywhere on the icons at the right side of the top of the screen to bring up a menu and click on Wi-Fi Not Connected then choose Select Network.
Scroll through the list and select the network you’d like to connect to and click Connect.
Enter the password and click Connect.
The Wi-Fi icon should now show the signal strength of the connection.
If you are installing using the live image, resume the installation process now. Your Wi-Fi configuration will automatically be included in the install.
