Setup Wireless – Advanced Page Description 
This section describes the section headings and fields descriptions of the Setup 
Wireless – Advanced page. 
 If you make changes in the Setup Wireless – Advanced page, click Apply 
to apply and save your wireless advanced settings. 
 
Field Name 
Description 
Basic Data Rates 
Displays the default initial data rate for associating with 
a WAP. For maximum client compatibility, it is 
recommended that the Basic Data Rates are set at  
1, 2 Mbps so that older cards can easily gain access to 
the network. This setting specifies the minimal set of 
required data rates 
Control Tx Rates 
Displays the transmit data rates the WAP uses is a 
function of signal strength and signal quality. For 
maximum potential link speed, it is recommended that 
you select all control Tx rates: 1, 2 Mbps, 5.5 Mpbs, 
and 11 Mbps 
Beacon Interval 
Displays the time interval that the WAP uses to 
announce itself to remote devices. The Beacon 
Interval should be left at 100ms for compliance with 
most client cards. The Beacon Interval specifies how 
often packets are sent by the Access Point (AP) to 
synchronize a wireless network and it’s clients 
DTIM Interval 
Displays the time interval between 
Broadcasts/Multicast transmissions. The DTIM 
(Delivery Traffic Indication Message) Interval is a 
countdown informing the wireless clients of the next 
window for listening to broadcast and multicast 
messages. When the AP has buffered broadcast or 
multicast messages for associated clients, it sends the 
next DTIM with a DTIM Interval value. AP clients hear 
the beacons and awaken to receive the broadcast and 
multicast messages. The DTIM Interval should be left 
at 3 ms for compliance with most client cards 
Fragmentation 
Threshold 
 
Fragmentation and ready to send (RTS) thresholds 
should be set equivalent to the maximum Ethernet 
frame size allowable on the link including overhead 
(1536 bytes). Lesser settings can damage data 
throughput as large frames could be fragmented or 
collisions could occur 
RTS Threshold 
The RTS/CTS threshold determines at what packet 
size beyond which the RTS/CTS mechanism is 
invoked.
