Wireless Configuration B - 7 Table B-5 Operating Mode Fields (Continued) Field Description Country Country determines if the profile is valid for the country of operation. The profile country must match the country in the options page or it must match the acquired country if 802.11d is enabled. Single Country Use: If using the device in a single country, set every profile country to Allow Any Country. In the Options > Regulatory dialog box (see Figure B-41 on page B-44), select the specific country in which the device is used, and deselect the Enable 802.11d option. This common and efficient configuration eliminates the initialization overhead associated with acquiring a country via 802.11d. Multiple Country Use: If using the device in more than one country, select Enable 802.11d in the Options > Regulatory dialog box (see Figure B-41 on page B-44). This eliminates the need for reprogramming the country (in Options > Regulatory) each time you enter a new country. However, this only works if the infrastructure (i.e., APs) supports 802.11d (older firmware versions on wireless infrastructures do not support 802.11d). When you select the Enable 802.11d option, the Options > Regulatory > Country setting is not used for infrastructure WLANs. 802.11d feature is only valid for Infrastructure WLANs. Ad-hoc WLANs use the country options and must match the profile. For a single profile to use in multiple countries, with infrastructure that supports 802.11d (including infrastructure), set the Profile Country to Allow Any Country. Under Options > Regulatory, select Enable 802.11d. The Options > Regulatory > Country setting is not used. For a single profile to use 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, always set the Options > Regulatory > Country setting to the country the device is currently in. You can use this efficient configuration option with any infrastructure. However, you must manually change the Options > Regulatory > Country setting when entering a new country. 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, which requires unique profiles for each country. For additional efficiency when using multiple profiles to use in multiple countries, set the country setting for each profile 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, that profile is disabled. This can speed profile roaming. For example, if you create and configure two profiles for Japan, and two more for USA, then when in Japan only the first two profiles are active, and when in USA only the last two are active. If you configure them all for Allow Any Country, all four are always active, making profile roaming less efficient. Tap Next. If you selected Ad-Hoc mode, the Ad-Hoc Channel dialog box displays. If you selected Infrastructure mode, the Security Mode dialog box displays. See Authentication on page B-10 for instruction on setting up authentication.
