Wireless Configuration
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

you can manually enter the MAC address of the authorized PC.
The MAC address is usually printed on the wireless card.

When you have finished entering MAC addresses, return to the Wireless Access List menu

Configuring Wired Equivalent Privacy (WEP)
In the Wireless Settings menu you can configure WEP data encryption from the Security

Select the WEP Encryption level:
Off - no data encryption (Open System)
64-bit (sometimes called 40-bit) encryption

Authentication Type
Select the appropriate value - "Open System" or "Shared Key." Check your wireless card's
documentation to see what method to use.
Keys
If WEP is enabled, you can manually or automatically program the four data encryption keys.
These values must be identical on all PCs and Access Points in your network.
Note:
If the
