The Wi-Fi Environment table in the sensor status page displays the Wi-Fi environment around the sensor from a periodic AP scan. The results include SSIDs, BSSIDs, RSSI values, channel information, and related information you can see by hovering over the (i) info element. The information in the table is now available to view as a chart, helping you visualize your channel plan and see areas free, with channel overlap or with channel interference.
The new Wi-Fi Environment has two views: A collapsed view and an expanded view you can access by clicking the full-screen icon.
Filters can be applied to simplify the charts and help narrow your focus to SSIDs, RSSI Signal, Channels, and Channel Widths. By default, filters are applied on RSSI to limit the chart view to show the BSSIDs with the best signal. You can click the filter icon and set the RSSI to your desired level. You can tell when a filter is applied by observing the blue dot on the filter icon.
There are also quick filter buttons for 2.4 GHz, 5 GHz or all
You can also search for specific SSIDs or BSSIDs. Please note the filter rules are applied to the search.
The horizontal scroll allows you pan across the channels
When you examine the table, when you mouse over a BSSID, the graphs will automatically navigate to and highlight the BSSID you are looking at.
The colors of the Wi-Fi Environment Visualization are as follows:
Green – The BSSID is currently being tested
Blue – A BSSID part of the SSID configured for testing
Light Grey – An SSID not being tested
Dark Grey (Dashed lines in the chart) – A Hidden SSID not being tested
Info bubble will provide the following details:
The vendor name and AP name displayed under the information bubble come from the Information Element field present in the Beacon packet. If you are seeing any missing information in the fields you can take an on-demand packet capture on the sensor and validate the information.
AP name:
In order to see the AP name, typically you need to set your SSID settings to advertise AP name.
Once you enable the AP name, you will also see the AP name under
Issue Triage Error context
BSSID test results chart
Sensors do support multivendor AP name display - if your Aruba, MIST, Cisco, Extreme, or Sagemcom(uses Microsoft OUI) AP advertises the AP name in the beacon frames, you can now see the AP name in the Wi-Fi Environment section under the (i) element for the SSID being tested, in issue triage context and in the BSSID test result chart when hovering your mouse over the BSSID test results.
Known limitations:
The Wi-Fi Environment displays the results of the most recent AP scan within the time window selected. For example, if you have selected the last 24-hour view, you will only see the most recent AP scan. If you are looking at a previous time period, the results will be the latest within that time period. You can mouse over the info element to identify the “last seen” to see what time you are looking at.
The results may differ slightly from one AP scan to the next, it depends on whether the sensor received a probe response from the AP.
