Country Code
Different countries have different power level requirements and frequency selections. To
ensure device operation follows regulatory compliance rules, make sure to select the
correct country code for the device location. The channel list, output power limits, and
IEEE 802.11 and Channel Spectrum Width modes will be tuned according to the
regulations of the selected country. Station setting must match the AP country code
setting.

If the No Country Set option is checked, only the following frequency ranges are
available:
available:
• 11n 2.4GHz (2412-2462MHz)
• 11n 5GHz (5180-5320MHz and 5745-5825MHz).
• 11n 5GHz (5180-5320MHz and 5745-5825MHz).
Wireless Profile
NA is the 11n 5GHz band and represents a mix of 802.11n and 802.11a mode.
NG is the 11n 2.4GHz band and represents a mix of 802.11n, 802.11g and 802.11b
mode.
mode.
NOTE: Station setting must match the AP Wireless Profile setting.
Channel Spectrum Width
20M represents data transmission at a bandwidth of 20MHz.
20/40M represents data transmission at either 20MHz or 40MHz. In a very noisy
environment it automatically falls back to 20MHz to be more resilient to the interference.
In situations where auto fallback does not happen, manually changing channel
spectrum width to 20MHz will help reduce interference on the link and improve
performance.

NOTE:
1. 40MHz bandwidth is non-standard for 802.11n/g mode operation. If you
experience unstable performance, change the Channel Spectrum Width to 20M.
2. Station setting must match the AP Channel Spectrum Width setting.

Channel Scan List
From a list of channels associated with the selected country code, you can choose
which channels are scanned when scanning for an Access Point. Then the scanned
channels will appear on the Site Survey.
