Chapter 2. Post-Installation Configuration > Configuring Wireless Networks

Configuring Wireless Networks

Wireless networking used to be a bear to configure for Linux, requiring a lot of complicated steps to connect to a wireless network. That has become a much easier task, and Ubuntu includes a great utility called Network Manager that makes connecting to and managing wireless networks extremely easy.

When you log in to Ubuntu, the Network Manager applet appears in the top panel (see Figure 2.9). This applet handles and monitors network connections.

Figure 2.9 The Network Manager notification applet, shown here already connected to a wireless network.

Click the applet icon in the toolbar to connect to a wireless network. If your wireless access point broadcasts its service set identifier (SSID), it should appear in the list under wireless networks. Click the desired network, and Network Manager detects what encryption (if any) is in use and asks you for the passkey. Enter this and Network Manager starts the wireless connection. The passkey is then stored in the default keyring, a secure area that is unique to your login. From now on, whenever you log in to Ubuntu and are in range of this network, Network Manager will start the connection automatically.
