The correspondence between WLAN interface names (wlan0, wlan0-1 etc.) and their SSIDs is not obvious. In the "Realtime graps - Traffic" and "Realtime graps - Wireless", only interface names are shown. In the "Network - Wireless" page, interface names are shown only for the connections, not for the networks themselves. If there are no connections, only the "Edit network" page shows the appropriate interface name. If the interfaces are not explicitly named, it is inconvenient to see the correspondence.
I think it would make sense to show interface names near their SSIDs on the "Network - Wireless" page, and on the "Realtime graps" page tabs.
