5-4 Optimizing Wireless Connectivity and Security

•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.

•Mode. This field determines which data communications protocol will be used.

•Security Options. These options are the wireless security features you can enable. The table

below identifies the various basic wireless security options.

•Allow Broadcast of Name (SSID). If you disable broadcast of the SSID, only devices that

have the correct SSID can connect. Disabling SSID broadcast nullifies the wireless network

‘discovery’ feature of some products such as Windows XP.

•Enable Wireless Access Point. If you disable the wireless access point, wireless devices

cannot connect to the WGR826V.

Table 5-1. Basic Wireless Security Options

Field Description

Disable No wireless security.

WEP WEP offers the following options:

Open System

With Open Network Authentication and 64- or 128-bit WEP Data Encryption, the WGR826V

does perform 64- or 128-bit data encryption but does not perform any authentication.

Shared Key

Shared Key authentication encrypts the SSID and data.

Choose the Encryption Strength (64- or 128-bit data encryption). Manually enter the key

values or enter a word or group of printable characters in the Passphrase box. Manually

entered keys are case sensitive but passphrase characters are not case sensitive.

Note: Not all wireless adapter configuration utilities support passphrase key generation.

Auto

WPA-PSK WPA-Pre-shared Key does perform authentication, uses 128-bit data encryption and

dynamically changes the encryption keys making it nearly impossible to circumvent.

Enter a word or group of printable characters in the Password Phrase box. These characters

are case sensitive.

Note: Not all wireless adapter configuration utilities support WPA. Furthermore, client software

is required on the client. Windows XP and Windows 2000 with Service Pack 3 do include the

client software that supports WPA. Nevertheless, the wireless adapter hardware and driver

must also support WPA.
