Wireless Directed Data Rate Below Min
Wireless data rates sensed on your network are falling below the minimum set in Expert Thresholds. Directed data is data that is addressed to a particular station, as opposed to 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.
