I installed Kismac about 3 months ago & it worked fine. However I came to use it this morning & it failed to locate the Airport driver. I uninstalled Kismac & the Sourceforge driver, downloaded the newest versions of both, then installed the Sourceforge wireless driver (rebooted) installed Kismac & the Sourceforge wireless driver patch (rebooted) but still get the same problem. I select "Apple Airport Extreme card (passive)" in the driver pane of Kismac's preferences, but it just replies that it "can't locate your Airport Extreme driver". I'm at a complete loss as to what to do!
