This powerful visualization now provides you insights into your device’s roaming history while at the same time highlighting if it roamed well, was connected to an AP at a low RSSI etc. to further assist in troubleshooting. We use the data from the Client Events and arrange it in an easy way to visualize the path your client takes. Bad roam statuses are marked when the RSSI is low, and a warning roam status occurs when the client jumps to a different radio band or WLAN during the roam.
The dots you see on here are called Transient Associations, which are simply just short interval associations with the AP. You may zoom in on the chart to get a more detailed view of the roaming during transient associations. Either use the + and – buttons on the top right of the timeline, or click and drag your cursor to zoom in on a specific time window. Here, we zoomed in on the row of transient associations in the 9:45am – 9:54am time range
Hover over the roam status icons on the timeline to view detailed information about the roam, such as the channel, band, and RSSI information. We can see that at 9:49am the client experienced a good roam between the APs:
A bad roam occurred here. Notice that we will indicate a low RSSI for these bad roam statuses:
Here, the client switched from the 5GHz radio band to the 2.4GHz band during its roam, so the roam status shows as warning.
The Marvis search for roaming works in both Natural Language and Query Language mode, and you may also specify the time range in your search as well.
