A: Check whether ALE is calculating the location of the missing client. We need to tail the location log to see whether location is getting calculated for that specific client or not. If location itself is not getting calculated then issue might be due to RSSI value, need to check on deployment side.

In above logs, we see client location is getting calculated by a unknown BSSID, We see such log entrees, if AP details missing in airwave or visualrf. Check whether this particular AP which is reporting this station is added to Airwave and also provisioned in VisualRF. ALE get AP location from VisualRF.
