Encryption - Select a level of WEP encryption, 40 / 64-bit (10 hex digits) or 104 / 128-bit (26 hex digits).

Passphrase - If you want to generate WEP keys using a Passphrase, then enter the Passphrase in the field provided and click the Generate.

Key 1 - If you want to manually enter a WEP key, then complete the field provided.  A WEP key can consist of the letters "A" through "F" and the number "0" through "9".  It should be 10 characters in length for 40/64-bit encryption or 26 characters in length for 104/128-bit encryption.

Enabling Wireless MAC Filter

Wireless access can be filtered using the Media Access Control (MAC) addresses of the wireless devices transmitting within your network's radius.  You can either permit or prevent specific wireless computers access to your wireless network.

To learn how to permit wireless computers to connect to your wireless network with MAC filtering, click here.

To learn how to prevent wireless computers to connect to your wireless network with MAC filtering, click here.

Disabling SSID Broadcast

This procedure will prevent other users from detecting your SSID or your wireless network name, when they attempt to view available wireless networks in your area.

NOTE:  Relying on a hidden SSID is not recommended since there are applications developed nowadays that would detect hidden networks.  To make sure your network is secured, set your wireless security mode to WEP, WPA, WPA2 or RADIUS.

 
Step 1:
Access the ADSL gateway’s web-based setup page.  For instructions, click here.

Step 2:
When the ADSL gateway’s web-based setup page appears, click Wireless.  Look for SSID Broadcast and select Disabled.
