ProSafe Dual Band Wireless N Access Point WNDAP350 Reference Manual

Basic Installation and Configuration 2-19

v2.0, April 2013

• Broadcast Wireless Network Name (SSID). If you disable broadcast of the SSID, only

devices that have the correct SSID can connect. This nullifies the wireless network

“discovery” feature of some products such as Windows XP, Vista and Unix systems but

the data is still fully exposed to a determined snoop using specialized test equipment like

wireless sniffers. Default is enabled.

• Channel/Frequency. From the pull-down menu, select the channel you wish to use on

your wireless LAN. The default is Auto. When you select Auto as the Channel Frequency,

then the only available Channel Width is Dynamic: 20/40MHz.

It should not be necessary to change the wireless channel unless you experience

interference (shown by lost connections and/or slow data transfers). Should this happen,

you may want to experiment with different channels to see which is the best. See the

article on “Wireless Channels” available on the NETGEAR website. (A link to this article

and other articles of interest can be found in Appendix B, “Related Documents.”). When

selecting or changing channels, some points to bear in mind:

– Access points use a fixed channel. You can select the channel used. This allows you to

choose a channel which provides the least interference and best performance. In the

USA and Canada, 8 channels are available.

– If using multiple access points, it is better if adjacent access points use different

channels to reduce interference. The recommended channel spacing between adjacent

access points is 8 channels (for example, use channels 36 and 44, or 44 and 52).

– In “Infrastructure” mode, wireless stations normally scan all channels, looking for an

access point. If more than one access point can be used, the one with the strongest

signal is used. This can only occur when the various access points are using the same

SSID.

• MCS Index/Data Rate. From the pull-down menu, select the transmit data rate of the

wireless network. Also, depending on the band selected, the set of rates will vary. The

default is Best.

The possible data rates supported are:

Note: Data rate is selected using MCS Index. The actual data rate is computed based

on MCS Index, Channel Width, and Guard Interval. When Channel Width

selected is Dynamic 20/40MHz or when Guard Interval is selected is Auto,

then the data rate for a client depends on associated clients channel width and

guard interval capabilities.
