selection from the drop-down list:
• g and b. In addition to 802.11b- and 802.11g-compliant
devices, 802.11n-compliant devices can connect to the
wireless access point because they are backward compatible.
• g only. 802.11g- and 802.11n-compliant devices can connect
to the wireless access point, but 802.11n-compliant devices
function below their capacity in 802.11g mode.
802.11b-compliant devices cannot connect.
• ng. This is the default setting. 802.11g- and 802.11n-compliant
devices can connect to the wireless access point.
802.11b-compliant devices cannot connect.
• GreenField. Only 802.11n-compliant devices can connect to
the wireless access point, and 802.1b- and 802.11g-compliant
devices cannot recognize the wireless access point, which
might cause interference. Therefore, use Greenfield mode only
when you are sure that there are no or very few 802.1b- and
802.11g-compliant devices in the wireless coverage area.

cannot recognize the wireless access point, which might cause
interference. Therefore, use Greenfield mode only when you
are sure that there are no or very few 802.1a-compliant
devices in the wireless coverage area.
