On a Thinkpad T60 with up-to-date Feisty, Atheros AR5418 and latest SVN for madwifi-ng as of yesterday (r2431 - need SVN as this card isn't supported in Feisty's version of madwifi-hal), I am having this problem. It consistently happens at my university where there are two competing wireless networks, "network A" and "network B". I only have access to "network B". Only "network A" shows in the nm-applet.

Earlier today I noticed that using "iwlist scan" produces all of the APs - both the ones I want to connect to, and the ones I'm not authorized to. However, using "wlanconfig ath0 scan" only shows the AP I don't want. The only difference I could see at the time, and mind you this was only once and may be coincidence -- is that the "network A" points were all on Channel 1, and the "network B" points were on Channel 7.

If I go into manual configuration, and disable roaming mode, in the "Network Settings" screen I can see all APs. Obviously the Network Settings screen and NetworkManager are using different method of scanning.

I will investigate a little more into NetworkManager/madwifi-ng, but I cannot replicate the problem until next week as it's fine on my home wireless.
