By default, a UXI sensor tests a wireless network by connecting to an access point that most clients would have associated with based on the sensor's position. UXI sensors achieve this by utilizing BSSID selection criteria that consider RSSI, throughput, and the likelihood of a stable connection. The BSSID selection is described in more detail here.
When troubleshooting issues, it can be helpful to lock the sensor to a specific access point, allowing it to run its test cycles against that access point. To do this, you can lock the sensor to test only your BSSID or the SSID of interest. BSSID locking is primarily helpful for tactical, short-term troubleshooting, and you should unlock the sensor from the BSSID when finished. The reason is that when an AP reboots, the BSSIDs will not be the same when the AP comes back online, and your sensors will report errors, such as "Wi-Fi BSSID Missing".
How to Lock and Unlock a Sensor to a BSSID in the Wireless Environment
The easiest way to lock a sensor to a BSSID is in the Wireless Environment section of the sensor status page. From this view, you can apply filters, drill down into the BSSIDs of interest, and toggle the BSSID lock by selecting the lock icon for any BSSID in blue or green.
Once set, you can verify that a BSSID lock is applied in the wireless environment and in the test result Wi-Fi BSSID graph if the lock icon is present.
To unlock a sensor from a BSSID, if the BSSID is still present, you can click the lock icon in the wireless environment or in the BSSID test result chart. However, if the BSSID is no longer present, you will need to unlock it from the settings described in the next sections.
BSSID Locking and Unlocking from the Group-Based Configuration Settings
For dashboards using the new group-based configuration, if you want to apply a BSSID lock or remove a BSSID lock, you can do so from the settings by going to
Go to Settings -> Sensors -> Assignment Tab
Search for the sensor in the assigned column on the right
Once you locate the sensor, select Network Settings to see network-specific settings for the sensor
Click the settings gear icon for the network setting you want to edit.
Choose locked or auto under BSSID Selection
BSSID Locking and Unlocking from the Legacy Configuration Settings
Go to the Sensor settings page
Click the pencil icon to edit a sensor
Add SSID (if not already there)
Click configure (for advanced configuration)
Choose locked or auto under BSSID Selection
