Check if your Wireless card is listed as supported on Linux here
http://linux-wless.passys.nl/

This is a good read too,
https://help.ubuntu.com/community/WifiDocs/WirelessCardsSupported

I found both of these links here :
https://help.ubuntu.com/9.10/switching/preparing-hardware.html

Hope this helps.

The NetworkManager applet was buggy in the Karmic Jaunty release but

of the privileged few too have experienced this.
