Enable and Disable Short Preambles with the CLI

The radio preamble, also called the header, is a section of data at the head of a

packet that contains information that the access point and client devices need when

sending and receiving packets. By default, a short preamble is configured, but you

can set the radio preamble to long or short:

 A short preamble improves throughput performance.

 A long preamble ensures compatibility between the access point and some older

wireless LAN cards. If you do not have any older wireless LAN cards, you should

use short preambles.

To disable short preambles and use long preambles, type:

no preamble-short

To enable short preambles, type:

preamble-short
