Scan for Wireless Networks on Ubuntu

Now that I'm beginning to travel more I run into situations where I need to search for wireless networks. Since I'm running Xubuntu some of the utilities that would exist in the more full featured desktops do not exist in Xubuntu but I found a few alternatives.

One solution is to install the wifi-radar package. Another that I found was running the following commands:

user@machine ~> sudo iwlist scan
user@machine ~> sudo iwconfig wlan0 mode Ad-Hoc {In this example wlan0 is the name of the wireless inteface}

The interface can also be edited with:
user@machine ~> sudo iwconfig
