Placement and Range

The operating distance or range of your wireless connection can vary significantly based on the

physical placement of the wireless gateway. For best results, place your gateway:

•

near the center of the area in which your PCs will operate,

•

in an elevated location such as a high shelf,

•

away from potential sources of interference, such as PCs, microwaves, and cordless phones,

•

away from large metal surfaces.

Wireless Settings

To configure the Wireless interface of your gateway, click on the Wireless Settings heading in the

Setup section of the browser interface. The Wireless Settings menu will appear, as shown in

Wireless Settings

In the Wireless Settings section are the following parameters:

•

Name (SSID)

Enter a Service Set ID (SSID) value of up to 32 alphanumeric characters. The same SSID must

be assigned to all wireless devices in your network. The default SSID is

Wireless

, but

NETGEAR strongly recommends that you change your network’s SSID to a different value.

•

Channel

This field determines which operating frequency will be used. It should not be necessary to

change the wireless channel unless you notice interference problems with another nearby

access point.

Restricting Wireless Access by MAC Address

By default, any wireless PC that is configured with the correct SSID will be allowed access to your

wireless network. For increased security, you can restrict access to the wireless network to only

allow specific PCs based on their MAC addresses.

Check the Turn Access Control On box to restrict access to you network to computers in the

Access Control List.

To access the Access List, click the Setup Access List button shown in
