Moving from one regulatory domain to another and channelization

Symptom(s):

Unable to determine how the channels work when I move an adapter from one regulatory domain to another. For example - I have a Japan adapter which does 802.11b channels 1 through 14, and I travel to the U.S. where only channels 1 through 11 are allowed.

Solution:

There are three basic regulatory channel ranges.

1 through 11 for Americas
1 through 13 for Europe
1 through 14 for Japan

When scanning (checking for available wireless networks) - the adapter only does active (transmitting) scanning on channels 1 - 11, and does passive (receiving only) scanning on channels 11+.

When in ad hoc mode (adapter to adapter) - only channels 1 to 11 are selectable or usable.

When in infrastructure mode (adapter to access point) - the channel that the adapter utilizes is the same as the access point (AP) is using. Hence the AP is assumed correct for its regulatory domain and the adapter is likewise using only allowed channels.
