| Wait, wifi0?  You need to be using 'eth0' or 'eth1', whichever eth
| device that 'iwconfig' reports. wifi0 is a historical airo anomaly
| that's only used for packet capture and sniffing of the 802.11 frames.
| It should not be used for anything other than Wireshark basically.
|
| Do you get the same behavior if you use the normal ethX interface of
| the airo device?

 Yes; on a 'bad' kernel, 'iwlist eth1 scanning' lists nothing, and on a
good kernel it lists the networks that I expect (with some variability;
where I have the machine at the moment is on the edge of visibility for
some networks, and they appear and disappear periodically).

| Note that just because wifi0 may return scan results doesn't mean it
| should be used with iwconfig...
|
| But also, you're doing the iwlist scan as root, correct?

 Yes (on both the good and the bad kernels).

 I haven't been trying to use iwconfig for anything; all of my actual
use of the wireless networks has been done through the Fedora 11 GUI.
