Bikeshed: wifi-status (monitor your wifi connection)
I work from coffee shops, pubs, and conferences quite a bit. That means lots and lots and lots of of WiFi.
Modern Ubuntu desktops have a handsome indicator applet with an animation that shows the connection process.
But I'm a geek, and I need to know in more detail what's happening with my wireless connection, especially when it seems like it's taking forever to get a wireless connection.
For this, I wrote a utility called wifi-status that's now in bikeshed. Run this from a terminal and you'll see both the iwconfig and ifconfig status of your wireless interface.
If you find this useful, install the bikeshed package from Natty, or from the Bikeshed PPA for other versions of Ubuntu.
