WiFi Security Tips :

1 ) Change default password

Make sure the router password is not still set to the default password. If the password can be guessed this could give someone access to the router setup, which could allow them to change your router settings, including viewing any security keys.

2 ) If available use WPA WPA2, not WEP

Many routers today will offer two different security schemes: WEP and WPA WPA2. We recommend WPA security, since it is more secure than WEP. However, for compatibility with some older devices such as gaming consoles, TiVo, and other network devices may only be able to use WEP, and WEP is better than no security.

3 ) Disable remote administration

When enabled, remote administration allows anyone close enough to your router to view or change your router settings. If you never plan on remotely administrating your network, e.g. wireless connecting to the router, we recommend disabling remote administration. With routers that support this option, it is often disabled through the Administration section.
After disabled, the router settings can still be changed using any computer connected to the router using a network cable.

4 ) Change the default SSID name

The SSID is the name that identifies your wireless router. By default, many routers will use the name of the router as the default SSID, for example, Linksys routers use ‘Linksys’ as the SSID. This is a security risk since it identifies the brand of the router and would let any attacker immediately know what exploits to use.
Tip: When naming the router do not use your family or any other identifiable information. For example, if the SSID contains your families last name it can identify by any neighbor.

5 ) Enable router firewall

Many routers also have their own firewall that can be enabled. If available, we also suggest enabling this feature as it helps add an extra layer of security for your network.

6 ) Disable SSID broadcast

To help make finding your wireless network easier wireless routers broadcast your SSID, which means anyone looking for a wireless router could see your SSID. To help make it more difficult for someone to find your network when browsing for a wireless network you can disable the SSID broadcast feature. However, when disabling the SSID broadcast it will require that you manually enter your unique SSID when wanting to connect any new device to your network.

7 ) Enable wireless MAC filter

The Wireless MAC filter feature only allows a wireless device to connect to your router if the MAC Address has been entered into the filter list. This can make connecting new devices to your network more difficult, but improves the overall security of your wireless network.
