Setting up wireless security on a Linksys router

Setting the security for your Linksys router helps keep your wireless network safe from unauthorized access.  These security options are built with your Linksys router to provide and maintain your network's security, and give you choices depending on what degree of security you want to use.

There are three (3) main options in setting up security measures for your network:

NOTE:  There are different wireless security modes with varying standards and improved features.  These may be available depending on the model of the router.   In addition, a combination of two (2) or three (3) of the mentioned security measures may also be employed for maximum wireless network security.

To set up wireless security on the Linksys router, follow the instructions below:

Enabling WEP or WPA/WPA2 wireless security key or password on the router

  • Wi-Fi Protected Access (WPA) is a type of wireless security which is dynamic in nature.  This means that it changes depending on the time renewal you will specify.
  • Wired Equivalent Protocol (WEP) is a type of wireless security which does not change.  It provides comparable confidentiality to a traditional wired network. 

For detailed instructions on setting up WEP, WPA or WPA2 wireless security on your router, click here.

NOTE:  The WPA/WPA2 wireless security is highly recommended over WEP for a higher level of security.  A WEP encryption is more susceptible to security breaches. 

Enabling Wireless MAC filter

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

Disabling the SSID Broadcast of the router

Disabling the SSID Broadcast is one way of securing your wireless network.  This will prevent other users from detecting your router’s wireless network name (SSID) when they scan available wireless networks in your area.  For instructions, click here.

NOTE:  If you disable the SSID Broadcast of your Linksys router, your wireless device will not be able to detect it once it searches for available wireless networks.  For instructions on how to connect to a wireless network with disabled SSID Broadcast, click here.


  • Changing important wireless settings like the wireless security mode, network password or wireless network name (SSID) while you have wireless devices connected to your network will temporarily disconnect the devices from the Internet.  You will need to reconnect the devices with the new wireless settings.  To learn how to connect wireless devices and gaming consoles to the network using Linksys Connect, click here.
  • If your computer, laptop and other wireless devices used to connect using the old wireless settings, ensure that you reconnect the devices to the network.  To learn how to connect wireless computers to your network, click here.
  • Disabling the SSID Broadcast may help protect your wireless network in some way, but for a stronger security on your network, it is recommended to use a higher security mode such as WPA2 and utilizing a unique password or passphrase.
