How to secure your wifi

The following tips will help you to use your Wi-Fi more securely and to protect your personal information.

Change the wireless network’s default name
A Service Set Identifier (SSID) is a name used so you can identify your network. You should change the network name from the router’s default. This can make it harder for anyone to identify the manufacturer of your router and guess its default settings.

Use encryption
Encryption scrambles messages sent over wireless networks so that they cannot be read easily. If your network is not encrypted, enable encryption on the wireless security settings page of your wireless router. There are different forms of encryption, but we suggest that you use the Wi-Fi Protected Access II (WPA2) version because it is stronger than other versions such as Wired Equivalent Privacy (WEP) and WPA.

On some devices, the encryption method in use will be displayed alongside the name of your wireless network name when you try to connect.

Choose a strong password
Change your password from a default supplied with the router. Make sure you use a password which is easy for you to remember but would be difficult for a stranger to guess, and preferably something with a combination of letters and numbers. Avoid using something obvious such as the name of your street.

Hide your network ID
A router broadcasts its SSID to anyone within range. You can alter the router settings to not broadcast the SSID and therefore avoid alerting hackers to the network’s existence.

Check that your device does not auto-connect to Wi-Fi signals
If your device is set to automatically connect to available open Wi-Fi networks, then you run the risk of automatically connecting to unknown and potentially dangerous networks. You should switch off auto-connect on your device settings page – refer to the manufacturer’s instructions for more details.
