Wireless settings describe aspects of the LAN related specifically to the wireless radio device in the AP (802.11 Mode and Channel) and to the network interface to the AP (AP MAC address).
Wireless regulations vary from country to country. Make sure you select the correct country code so that the AP complies with the regulations in your country. The country code selection affects the wireless radio modes the AP can support as well as the list of channels and transmission power of the wireless radio. 802.11d Regulatory Domain Support Enabling support for IEEE 802.11d (World Mode) on the AP causes the AP to broadcast which country it is operating in as a part of its beacons and probe responses. This allows client stations to operate in any country without reconfiguration.Disabling 802.11d prevents the country code setting from being broadcast in the beacons. However, this only applies to radios configured to operate in the g band (2.4 GHz band). For radios operating in the a band (5 GHz band), the AP software configures support for 802.11h. When 802.11h is supported, the country code information is broadcast in the beacons. MAC Address A MAC address is a permanent, unique hardware address for any device that represents an interface to the network. The MAC address is assigned by the manufacturer. You cannot change the MAC address. It is provided here for informational purposes as a unique identifier for an interface. The Mode defines the Physical Layer (PHY) standard the wireless radio uses.
Select the Channel.The range of available channels is determined by the mode of the wireless radio interface and the country code setting. If you select Auto for the channel setting, and Auto channel is configured, the AP scans available channels, immediately selects a channel and begins operation. If interference or errors occur on that channel, another channel is automatically selected.The Channel defines the portion of the wireless radio spectrum the wireless radio uses for transmitting and receiving. Each mode offers a number of channels, depending on how the spectrum is licensed by national and transnational authorities such as the Federal Communications Commission (FCC) or the International Telecommunication Union (ITU-R).
Note: After you configure the wireless settings, you must click Apply to apply the changes and to save the settings. Changing some settings might cause the AP to stop and restart system processes. If this happens, wireless clients will temporarily lose connectivity. We recommend that you change AP settings when WLAN traffic is low.
