Change the guard interval for a radio

From the menu, select the guard interval, which protects radio transmissions from
interference. The WiFi mode (see Change the WiFi mode for a radio on page 88)
determines if you can set the guard interval, and if so, which guard intervals are available.
For the 11a, 11b, and 11bg WiFi modes, you cannot set the guard interval at all.
Use the following guidelines:
• A shorter guard interval supports more throughput in an environment in which WiFi
devices operate at a shorter distance from the access point.
• A longer guard interval works well in an environment with multiple SSIDs and WiFi
devices that operate at a longer distance from the access point.
• Some legacy devices can operate with a long –800ns guard interval only.
To change the guard interval for a radio:
1. Launch a web browser from a computer that is connected to the same network as
the access point or directly to the access point through an Ethernet cable or WiFi
connection.
2. Enter the IP address that is assigned to the access point.
A login window displays.
If your browser displays a security warning, you can proceed, or add an exception
for the security warning. For more information, see What to do if you get a browser
security warning on page 43.
3. Enter the access point user name and password.
The user name is admin. The password is the one that you specified. The user name
and password are case-sensitive.
