Home networks, especially the WiFi networks we all know and love, are very hard to keep secure. But there are things you can do to make life much harder on the potential attacker.
Change your router’s default administrator password. Almost all network devices are pre-configured with default passwords to simplify setup and initial operation. Anyone with access to the Internet can find lists of default passwords for devices. This means if you don’t change yours bad guys can easily log in as administrator and change settings and take control of your net. This is a big deal. Change those default passwords!
Ensure you are using the strongest encryption protocol available. Any new wireless router will give you options for using stronger encryption. At this time that is WiFI Protected Access 2 (WPA2), with Personal Advanced Encryption Standard (AES) and Temporary Key Integrity Protocol (TKIP). Routers vary in how these are configured so you will have to consult your router’s instruction manual. But it is easier to do than it may sound.
Change your default WiFi network name. This is the name people see when they turn on their phone or tablet or computer near your WiFi. The default name may reveal information about the device you don’t want to be known. The WiFi network name is called Service Set Identifier (SSID). Make sure your network name is unique but does not identify your location or identity (suggestion: name it after your favorite planet, star or element).
