This feature provides you with another level of security by selecting a Key value.

•A single button is available for each WEP key up to a maximum of four keys.

•Pushing any of these buttons brings up an on-screen keyboard. Keys should be entered in hexadecimal notation. It is common practice for every two characters (representing a single byte) to be separated by a colon.

•Press Done to accept any changes and save the new value.

•Ex: 01:0A:67:F3:56, although this is not necessary and the key may be entered by omitting the colons. A 64-bit key will be 10 characters in length while a 128-bit key will be 26 characters in length. The length of the key entered determines the level of WEP encryption employed.

Either 64-bit or 128-bit.

•128-bit keys may also be entered and are used if supported by the internal wireless card.

Displays the current WEP key in use. Keys may also be examined by touching the key buttons and noting the keyboard initialization text.

•When working with a single panel and a single WAP, it is recommended that you manually enter the Current Key from the WAP into the selected WEP Key.

•When working with a single WAP and multiple panels, it is recommended that you generate a Current Key using the same passphrase on all panels and then enter the panel-produced WEP key manually into the Wireless Access Point.

The RF channel being used for connection to the WAP (read -only).

• This is determined through the WAP.

Displays the current quality of the link (as descriptive colored text) from the wireless NIC to the Wireless Access Point in real time.

•The bargraph has been replaced with a descriptions: None, Poor, Fair, Good, Very Good, and Excellent. Green color text indicates better communication quality.

•It reports the quality of the signal over the air (direct sequence spread spectrum). Even when the link quality is at its lowest you still have a connection and with it the ability to transmit and receive data, even if at much lower speeds.

Note: Both Link Quality and Signal Strength are applicable to the RF connection only. It is quite possible to have an RF signal to a Wireless Access Point but be unable to communicate with it because of either incorrect IP or encryption settings.

SNR (Signal Noise Ratio) is a measure of the relative strength of a wireless RF connection. This indicator displays a description of the signal strength from the Wireless Access Point connection.

•The bargraph has been replaced with a descriptions: None, Poor, Fair, Good, Very Good, and Excellent. Green color text indicates better signal strength.

•Given this value and the link quality above, a user can determine the noise level component of SNR.

Ex: If the signal strength is high but the link quality is low then the cause of the link degradation is noise. However, if the signal strength is low and the link quality is low the cause would simply be signal strength.
