DESCRIPTION
Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to associate with
the Device.
Select 802.11g Only to allow only IEEE 802.11g compliant WLAN devices to associate with
the Device.
Select 802.11n Only to allow only IEEE 802.11n compliant WLAN devices to associate with
the Device.
Select 802.11b/g Mixed to allow either IEEE 802.11b or IEEE 802.11g compliant WLAN
devices to associate with the Device. The transmission rate of your Device might be
