Wicd on Ubuntu - Wicd WikiCode:Configuration of Wicd is extremely simple, and automatic for wired clients. To configure a wireless connection: 1. Open the Wicd network manager in Applications > Internet > Wicd Network Manager (you may also click the tray icon if present). 2. See if the wireless network you're looking for shows on the list. If it is a hidden network, click the down arrow next to the Network button, and type in the ESSID of the network. 3. If the network you want to connect to is listed, press the "Connect" button next to it. 4. If you get the message "This network requires encryption to be enabled." hit OK, then click the arrow next to the network name. 5. Hit the "Advanced Settings" button. 6. Check the "Use Encryption" checkbox, choose your encryption type and type in the key. You may also assign a static IP or DNS in here, but most users will not need to. 7. Hit OK. 8. Now hit connect again. This time the connection should come up relatively quickly. 9. If you plan to use this connection all the time, consider pressing the "Automatically connect to this network" checkbox. You have to open the arrow next to the network name to choose it.
Little bit of "Google-Fu" will get you far.
