Advanced Wireless Settings

Configure the advanced settings for the Wireless Router. The Wireless-N Router adopts several
new parameters to adjust the channel bandwidth and guard intervals to improve the data rate
dynamically. Linksys recommends to let your Wireless Router automatically adjust the
parameters for maximum data throughput.
Advanced Wireless
You can change the following advanced parameters (some only for Wireless-N) for this Wireless
Router. Wireless-N data rates are classified into 16 MCS numbers (0-15). MCS stands for
Modulation and Coding Scheme. For the same MCS number, the data rate changes according
to the Channel Bandwidth and Guard Interval settings. You can see the change through the
drop-down menu of Tx Rate Limiting (11n clients).
Channel Bandwidth—Select the channel bandwidth manually for Wireless-N connections.
When it is set to 20MHz, only the 20MHz channel is used. When it is set to 40MHz, Wireless-N
connections will use 40MHz channel but Wireless-B and Wireless-G will still use 20MHz channel.
The default is Auto.
Guard Interval—Select the guard interval manually for Wireless-N connections. The two
options are Short (400ns) and Long (800ns). The default is Auto.
CTS Protection Mode—CTS (Clear-To-Send) Protection Mode function boosts the Wireless
Router's ability to catch all wireless transmissions, but will severely decrease performance. Keep
the default setting, Auto, so the Wireless Router can use this feature as needed, when the
Wireless-N/G products are not able to transmit to the Wireless Router in an environment with
heavy 802.11b traffic. Select Disabled if you want to permanently disable this feature.
Beacon Interval— Indicates the frequency interval of the beacon. A beacon is a packet
broadcast by the Wireless Router to keep the network synchronized. A beacon includes the
wireless networks service area, the Wireless Router address, the Broadcast destination
addresses, a time stamp, Delivery Traffic Indicator Maps, and the Traffic Indicator Message
(TIM). The default is 100 ms.
