Setting Up and Configuring the Router
Wireless Tab
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.
