Insight Cloud Managed WiFi 6 AX3600 Access Point Model WAX620 • Dynamic 20 / 40 MHz. This selection is available only for the 2.4 GHz radio and is the default setting for that radio. • Dynamic 20 / 40 / 80 MHz. This selection is available only for the 5 GHz radio and is the default setting for that radio. 6. Click the Apply button. A warning pop-up window displays. 7. Click the OK button. The pop-up window closes and your settings are saved. The radio or radios restart and WiFi clients might need to reconnect. 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. Manage the Basic Radio 91 Features User Manual
