Monitor Radios

Applies To: Wi-Fi Cloud-managed Access Points (AP125, AP225W, AP325, AP327X, AP420) This topic applies to Wi-Fi 5 access points you manage in Wi-Fi Cloud (AP120, AP125, AP225W, AP320, AP322, AP325, AP327X, AP420).

In Discover, the Monitor > WiFi > Radios page shows the status of all AP radios on the 2.4 GHz and 5 GHz bands. The page also includes a list of clients that are recently associated to the selected radio. The list of recent associations are those that occurred in the last four hours or the latest 100 clients. This value is the total number of associations in the system and not per device.

You can freeze columns, add or remove columns, filter the display, and switch to full screen mode using the icons at the top-right of the page. For more information, see Table Actions for Monitor Pages.

The data in the columns represent live data updated every 15 minutes.

The radio properties include this information:

Properties	Description
Status	Indicates if the radio is active (Green) or inactive (Red)
Name	Name of the AP.
MAC Address	The MAC address of the AP.
IP Address	The IP address of the AP.
Device Template	The device template applied to the device.
Channel	The channel number on which the AP radio operates.
Channel Width	The channel width for the AP radio.
Clients	The number of clients connected to the radio.
Tx. Power (dBm)	The transmission power of the radio.
Frequency	The frequency on which the radio operates.
RF Utilization	The frequency utilization displayed as a percentage.
Upstream Usage	Indicates upstream data usage.
Downstream Usage	Indicates downstream data usage.
Worst Client RSSI (dBm)	Displays the worst client signal strength.
Retry Rate (%)	The re-transmission rate displayed as a percentage.
Location	Displays the radio location.
Model	Displays the device model name.
Noise Floor (dBm)	Indicates the difference between the strength of the signal and the background noise level.

AP Radio Actions

You can enable or disable specific radios on an AP. For example, in deployments where you have multiple APs with both 2.4 GHz and 5 GHz radios enabled, you might have an excess of 2.4 GHz signal that causes interference because only three non-overlapping channels are available in the 2.4 GHz band. In these deployments, you can turn off the 2.4 GHz radio for some APs to reduce interference and maintain 2.4 GHz coverage.

• To enable or disable a radio, the AP must be active, and the radio must not be part of a mesh network.
• When you disable a radio, all SSIDs on that radio are unavailable. At least one radio must be available to make sure you do not interrupt Wi-Fi availability in the coverage area of the AP.
• It might take a few minutes to enable or disable a radio. The radio appears in italics until the status changes.
• A radio that you manually disable is not enabled automatically when the AP reboots or when an SSID of that AP is scheduled to be available.
• You can only enable or disable Wi-Fi access radios. You cannot disable dedicated WIPS scanning radios on tri-radio APs.

To enable or disable a radio on an AP:

1. Open Discover.
2. Select the location of the AP.
3. Select Monitor > WiFi, then select the Radios tab.
4. Right-click the radio, then select Turn Radio Off or Turn Radio On.
