Wireless Data Rate Below Average
Wireless data rates sensed on your network are falling below the average rate as measured by Observer during the current session. This metric includes both directed data and broadcast data.
Possible reasons for this event:
Stations negotiate a slower data transfer rate with an AP when the signal quality falls below the level needed to support the maximum rate.
A user has set up a station's card to force it to the slower transfer rate.
Someone has changed an AP's administrative settings to force the AP to negotiate slower data transfer rates.
