Configuring Wireless Settings

To configure advanced wireless settings for the router, follow these steps:

STEP 1 Click Wireless > Advanced Settings.

STEP 2 Configure the advanced wireless settings as needed by changing the following advanced parameters (some only for Wireless-N) for this 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.

•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 use 40MHz channel but Wireless-B and Wireless-G connections 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.
