Set the minimum bitrate to 12mbps for a standard environment and 24mbps to a higher density environment.
The minimum basic rate is the lowest data rate that an AP will transmit to client devices. If a client device supports a maximum rate below the minimum basic rate, it will not be able to connect to the AP. This allows you to keep older devices off of a network to increase efficiency for current client devices.
