Command Usage
◆ The available channel settings are limited by local regulations, which
determine the number of channels that are available.
◆ The available channels depend on the radio interface, either 11b/g/n (2.4 GHZ)
or 11a/n (5 GHz).
◆ The access point provides a channel bandwidth of 20 MHz by default giving an
802.11g connection speed of 54 Mbps and a 802.11n connection speed of up
to 108 Mbps, and ensures backward compliance for slower 802.11b devices.
Setting the HT Channel Bandwidth to 40 MHz increases connection speed for
802.11n up to 300 Mbps.
◆ HT40plus indicates that the secondary channel is above the primary channel.
HT40minus indicates that the secondary channel is below the primary channel.
◆ For most wireless adapters, the channel for wireless clients is automatically set
to the same as that used by the access point to which it is linked.
