Is your AP using channel 13 or something like that by any chance?
Then you'll need to load mac80211 with the option ieee80211_regdom=64 to
make this work. Add

options mac80211 ieee80211_regdom=64

to modprobe.conf and reload the mac80211 module.

If it is a recent kernel (2.6.24) then this needs to be:

options cfg80211 ieee80211_regdom="JP"

instead.

I had a problem with the iwlwifi driver in this regard, my AP is on
channel 12. Scanning found it, but it wouldn't associate. The option
string above fixed it for me.

FWIW, that was recently "fixed", scanning will no longer find it.
