Advanced Wireless
 Data Rate: Select the operating wireless data rate.
 Transmit Power: The wireless transmit power can be modified to lower the
antenna strength setting from 18 dBm to 11 dBm, if necessary. Lowering the
wireless transmit power may help to better stabilize the wireless connectivity and
reduce the effects of wireless interference in areas where there are several 2.4GHz
wireless devices. (Default: 18 dBm)
 RTS/CTS Threshold: The Request To Send (RTS) function is part of the networking
protocol. A wireless device that needs to send data will send a RTS before sending
the data in question. The destination wireless device will send a response called
Clear to Send (CTS). The RTS Threshold defines the smallest data packet size
allowed to initiate the RTS/CTS function.
Default Value: 2347 (range: 256-2346)
 Beacon Period: A beacon is a management frame used in wireless networks that
transmitted periodically to announce the presence and provide information about
the access point’s wireless network. The interval is the amount time between each
beacon transmission.
 DTIM: DTIM is a countdown informing clients of the next window for listening to
broadcast and multicast messages. When the access point has buffered broadcast
or multicast messages for associated clients, it sends the next DTIM with a DTIM
Interval value. Wireless clients detect the beacons and awaken to receive the
broadcast and multicast messages. The default value is 1. Valid settings are
between 1 and 255.
HT Physical Mode
 Guard Interval: Select to enable short guard interval (400ns).
 A-MPDU: MPDU aggregation also collects Ethernet frames to be transmitted to a
single destination, but it wraps each frame in an 802.11n MAC header. Normally
this is less efficient than MSDU aggregation, but it may be more efficient in
environments to maintain performance in noisy networks and to prevent hidden
nodes from degrading the performance.
Client Limit
 Client Limit: Select enable to turn on client limit of the select wireless band
 Max Client: Enter the amount of clients to allow
