What James told you is true but incomplete. Some hardware (including the iwl3945 and iwl4965) will refuse to tune to channels that are not on the "approved" list according to their firmware. However, this is not the only possible restriction. The mac80211 component will restrict the tunable channels as well, according to it's configured regulatory region. The default region is 'US', corresponding to the regulations specified by the FCC. Currently there is one other region defined, 'JP', corresponding to the regulations specified by the MKK in Japan. There currently is not a region specified for Europe, although there is some discussion about including one. In the long run we will likely support a more flexible regulatory enforcement scheme, allowing for a wide variety of localized regulations. Anyway, if you want access to more channels you might try adding a line like this to /etc/modprobe.conf: options cfg80211 ieee80211_regdom='JP' That should enable channels 1 through 14 -- be sure only to use channels approved in your area.
