Country
(Continued)
For a single profile that can be used in multiple countries, but with infrastructure that does
not support 802.11d, set the profile country to
Allow Any Country
, and de-select (uncheck)
Enable 802.11d
. In this case, the
Options > Regulatory > Country
setting must always be
set to the country the device is currently in. This configuration option is the most efficient
and may be chosen for use with any infrastructure. However, the
Options > Regulatory >
Country
setting must be manually changed when a new country is entered.
Note that using a single profile in multiple countries implies that there is a common ESSID
to connect to in each country. This is less likely than having unique ESSIDs in each
country, this requires unique profiles for each country.
For additional efficiency when using multiple profiles that can be used in multiple
countries, the country setting for each profile can be set to a specific country. If the current
country (found via 802.11d or set by
Options > Regulatory > Country
when 802.11d is
disabled) does not match the country set in a given profile, then that profile is disabled.
This can make profile roaming occur faster. For example, if two profiles are created and
configured for Japan, and two more profiles are created and configured for USA, then
when in Japan only the first two profiles are active, and when in USA only the last two are
active. If they had all been configured for
Allow Any Country
, then all four would always
be active, making profile roaming less efficient.
