Allow Data Rate Fallback
Determines if you want the radio to drop to a slower data rate
when it has trouble communicating with another radio.
Basic Rate
Choose the rate at which the access point transmits multicast and
beacon frames. In general, higher speeds mean shorter range and
lower speeds mean longer range. Do not set this rate higher than
the maximum rate at which your end devices can receive
multicast frames. You can set this rate to 11, 5.5, 2, or 1 Mbps. This
parameter should usually be left at the default 2 Mbps.
Enable Medium Reservation
Determines if you want to specify a reservation threshold. Check
this check box to set a threshold value. If you clear this check box,
you may improve network response time in installations that
usually send very small frames or that have no hidden stations.
Reservation Threshold
If you enable medium reservation, you need to set a threshold
value, which is the largest data frame that can be transmitted
without reserving air time. Air time is normally reserved to help
prevent collisions with other transmitters.
Distance Between APs
Controls the roaming sensitivity of your end devices. This setting
should match the setting on your end devices.
You can use this parameter to virtually reduce the range of your
access point. If you choose Small or Medium, you do not reduce
the absolute range of your radio, but you modify the collision
detection mechanism to allow significant overlap of the wireless
cells. Thus, you create a higher performance radio network, but
you need more access points to cover an area.
Enable Microwave Oven Robustness
Determines if the access point activates a modified algorithm for
automatic rate fallback, which prevents the access point from
falling back to 1 Mbps when trying to retransmit radio frames
when 2.4 GHz interference is present.
Enable Load Balancing
Determines if end devices can distribute their connections across
multiple access points.
