Appendix C: Wireless Security

Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of 
Linksys products provide several network security features, but they require specific action on your part for 
implementation. So, keep the following in mind whenever you are setting up or using your wireless network.

Security Precautions

The following is a complete list of security precautions to take (at least steps 1 through 5 should be followed):

1. Change the default Wireless Network Name (SSID). 

2. Disable SSID Broadcast. 

3. Change the default password for the Administrator account. 

4. Enable MAC Address Filtering. 

5. Change the SSID periodically. 

6. Use the highest encryption algorithm possible. Use WPA or WPA2 if it is available. Please note that this may 

reduce your network performance. 

7. Change the WEP encryption keys periodically. 

Security Threats Facing Wireless Networks 

Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking 
products first listen for “beacon messages”. These messages can be easily decrypted and contain much of the 
network’s information, such as the network’s SSID (Service Set Identifier). Here are the steps you can take:

Change the administrator’s password regularly. With every wireless networking device you use, keep in mind that 
network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the only person 
who can change network settings. If a hacker gets a hold of the administrator’s password, he, too, can change 
those settings. So, make it harder for a hacker to get that information. Change the administrator’s password 
regularly.

SSID. There are several things to keep in mind about the SSID: 

Note: Some of these security features are 
available only through the network router or 
access point. Refer to the router or access 
point’s documentation for more information.
