<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">I am trying to use a Wifi adapter on an IBM Thinkpad. In the Ubuntu Documentation, at the following web location: https://help.ubuntu.com/community/HardwareSupportComponentsWirelessNetworkCardsAirlink101 there is a list of Wifi cards (by Manufacture), that have been tested to work with Ubuntu. Please note that there is a grid detailing various categories of installation procedures required.  One of the headings of the grid is entitled "Supported In Installed System."  I don't understand what "Supported In Installed System" means.  Apparently there is some sort of "installation" that it is referring to, but I don't know what. Could you kindly explain what procedures and/or installations are required to use a Wifi card that is identified as being able to work under that category. Thank you, Evan Murri </td></tr></table>
