Data Rate Settings

You use the data rate settings to choose the data rates the AP uses for data transmission. The rates are

expressed in megabits per second. The AP always attempts to transmit at the highest data rate set to

Basic, also called Require on the browser-based interface. If there are obstacles or interference, the AP

steps down to the highest rate that allows data transmission. You can set each data rate (1, 2, 5.5, and 11

megabits per second) to one of three states:

•

At least one data rate must be set to basic.

Basic (this is the default state for all data rates)—Allows transmission at this rate for all packets,

both unicast and multicast. At least one of the access point's data rates must be set to Basic.

Enabled—The AP transmits only unicast packets at this rate; multicast packets are sent at one of the

data rates set to Basic.

Disabled—The AP does not transmit data at this rate.
