Set Rates Click the Set Rates button to define minimum and 
maximum data transmit rates for the radio. 
Use the Basic Rates drop-down menu to select the rates 
available for either the 2.4 GHz or 5 GHz radio band. The 
menu options differ, based on the radio band. 
For 2.4 GHz, the following options are available:
• 1 and 2 Mbps
• 1, 2, 5.5 and 11 Mbps (default setting)
• 1, 2, 5.5, 11 and 6, 12, 24 Mbps
• 1, 2, 5.5, 11 and 6, 12, 24 Mbps and MCS 0-7
• 6, 12 and 24 Mbps
• 6, 12 and 24 Mbps and MCS 0-7
• MCS 0-7
For 5 Ghz, the following options are available:
• 6, 12 and 24 Mbps
• 6, 12 and 24 Mbps and MCS 0-7
• MCS 0-7
When a basic rate option is selected (from the drop-down 
menu), the rates are automatically selected and grayed out 
in the Supported Rates radio boxes. Select remaining 
rates as needed for additional supported rates. 
Enable the Support Short Guard Interval checkbox to set a 
guard interval (for interference protection) for 20 MHz and 
40 MHz channel widths. When enabled, the AP’s radio 
defines values to enable a packet to be transmitted with 
guard interval based on the configuration and capabilities 
of associated clients. Clients can associate to an Access 
Point regardless of whether they support a short guard 
interval. 
If supporting 802.11n, select a Supported MCS index (0-
15). Set a MCS (modulation and coding scheme) in 
respect to the radio’s channel width and guard interval. A 
MCS defines (based on RF channel conditions) an optimal 
combination of 8 data rates, bonded channels, multiple 
spatial streams, different guard intervals and modulation 
types. MUs can associate as long as they support basic 
MCS (as well as non-11n basic rates).
Click OK to implement the selected rates and return to the 
radio configuration screen. Clicking Cancel reverts the Set 
Rates screen to the last saved configuration.
