I'm using the iwl3945-driver, and haven't had a problem at home using HW-scan. At my parents, on the other hand, which uses the same ssid and the same wep-key, it doesn't work. 1 out of 10 'iwlist scan' failes to see anything at all. I haven't tested with disable_hw_scan=1 yet though. But I can try it the next time I'm visiting them, and post my results here. Are there anything else information about these APs that anyone might be interested in? Except for the key? ;-) - Tor H.
