This is the third in a series of 12 tips to help you improve your online safety.
Change the administrator password (and username if you can) #
Sites like DefaultPassword.com are really handy if you need to reset a device and no longer have the manual to hand, but are similarly handy to hackers.
Disable WPS #
WiFi Protected Setup (WPS) allows you to pair a device with the router by simply pressing a button. Because of the way the encryption is implemented, it's really easy to crack, so should be turned off in the router's menu.
Use secure guest networks for Connected Devices / Internet of Things #
Guest networks are often poorly set up without a password, but used well, they can give you a security boost. The main advantage of a guest network is that it's separated from the rest of your network, so by default, can only get to the internet, and not to your other devices. Set a strong password to it, and use the guest network for Internet of Things devices like wireless-connected lightbulbs.
If you have a wireless printer, enable security #
Use MAC address filtering #
All hardware devices have a Media Access Control (MAC) address which uniquely identifies it. Configure your wireless router to only allow your own devices to have access. (E.g. instructions for Virgin Super Hubs)
Use a schedule to turn Wi-Fi off #
Most wireless routers have a function which can turn the wireless network on or off on a schedule. Although there's an obvious security benefit to this, you might find that when Facebook suddenly stops working (for you or your teenager), this is a useful prompt to go to bed.
