Setting up wireless security on a Linksys ADSL Gateway is a simple process, which generally does not require a lot of time. This can be done by:
Enabling Wireless Security Mode
Enabling Wireless MAC Filter
Disabling SSID Broadcast
Enabling Wireless Security Mode
To set up Wireless Security on your Linksys ADSL Gateway, follow the steps below.
Step 1:
Launch a browser and enter 192.168.1.1 in the Address bar to access the ADSL gateway’s web-based setup page. For instructions, click here.
NOTE: If you're using a Mac®, click here for instructions. The default Username and Password is admin.
Step 2:
On the ADSL gateway's web-based setup page, click Wireless then click Wireless Security.

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.
