Wireless communications and channels are tightly regulated in every country on Earth, and this applies to Wi-Fi networks as well. Not every one of 14 pre-defined Wi-Fi frequencies is allowed to be used in every country. It is your responsibility to set a correct "domain" for your Wi-Fi device. This is done through the wln.domain property.
The following domains are supported by the wln object:
| • | Domain "FCC" (US, Canada, Taiwan): channels 1-11. |
| • | Domain "Spain": channels 10, 11. |
| • | Domain "France": channels 10-13. |
| • | Domain "Japan": channels 1-14. |
| • | Domain "other": channels 1-13. |
Your application must select correct domain prior to booting up the Wi-Fi interface. Selecting the domain will restrict the channels on which the Wi-Fi interface will associate with the network. Scanning won't be affected and will discover all networks on all 14 channels.
