Advanced Sengs
Advanced > Wireless (2.4GHz or 5GHz) > Advanced
These sengs are advanced opons that can be congured to change advanced wireless
broadcast specicaons. It is recommended that these sengs remain set to their default
values unless you are knowledgeable about the eects of changing these values. Changing
these sengs incorrectly can degrade performance.
1 Log into your router management page (refer to “Log in to Management Page” on page 8).
2 Click on Advanced > Wireless (2.4GHz or 5GHz) > Advanced.
3 In Advanced Wireless secon, congure the following parameters:
 Beacon Period: A beacon is a management frame used in wireless networks that
transmied periodically to announce the presence and provide informaon on the
router’s wireless network. The interval is the amount me between each beacon
transmission.
 Default Value: 100 milliseconds (range: 100-1000)
 DTIM: A DTIM is a countdown informing clients of the next window for listening to
broadcast and mulcast messages. When the wireless router has buered broadcast
or mulcast 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 mulcast messages. The default value is 1. Valid sengs are between
1 and 255.
 Fragment Threshold: Wireless frames can be divided into smaller units (fragments)
to improve performance in the presence of RF interference and at the limits of RF
coverage. Fragmentaon will occur when frame size in bytes is greater than the
Fragmentaon Threshold. This seng should remain at its default value of 2346
bytes. Seng the Fragmentaon value too low may result in poor performance.
 RTS Threshold: The Request To Send (RTS) funcon is part of the networking protocol.
A wireless device that needs to send data will send a RTS before sending the data in
queson. The desnaon wireless device will send a response called Clear to Send
(CTS). The RTS Threshold denes the smallest data packet size allowed to iniate the
RTS/CTS funcon.
 Default Value: 2347 (range: 1-2347).
 TX Power: This seng allows you to adjust the wireless transmit power to a lower
seng. In busy wireless environments, lowering the transmit power may improve
beer performance and connecvity and decrease interference with neighbouring
wireless networks.
 Short Preamble: Using a short preamble can potenally increase throughput as the
transfer me is 96 microseconds versus the more commonly used long preamble
192 microseconds. However, using a short preamble is not supported using 802.11b
legacy devices, in some cases cause wireless interoperability issues, and increase
the error rate in some installaons. The preamble is the informaon sent from the
wireless transmier to the receiver indicang when data is incoming.
4 In HT Physical Mode secon, congure the following parameters:
 20/40 Coexistence (2.4GHz only): 20/40MHz Coexistence allows for the auto-fallback
from 40MHz to 20MHz channel width operaon when neighbouring 802.11 wireless
networks are detected.
 Guard Interval: Using a short (400ns) guard interval can increase throughput.
However, it can also increase error rate in some installaons, due to increased
sensivity to radio-frequency reecons.
 MCS: Allows you to lock down the wireless transmission rate.
 Extension channel: Allows you to assign either the upper or lower extension channels
to use for channel bonding when establishing connecvity at the higher channel
widths 40MHz and 80MHz.
 A-MPDU: Using Aggregate Mulple Protocol Data Unit will allow the all frames
transmied to be aggregated into larger size A-MPDU formaed frames before
sending and receiving potenally increasing the overall throughput.
