A wireless network means connecting an internet access point – such as a cable or DSL modem – to a wireless router. Going wireless is a convenient way to allow multiple devices to connect to the internet from different areas of your home. However, unless you secure your router, you’re vulnerable to people accessing information on your computer, using your internet service for free and potentially using your network to commit cybercrimes. One quick fix is to change the name of your router: The default ID – called a service set identifier” (SSID) or “extended service set identifier” (ESSID ) – is assigned by the manufacturer. Change your router to a name that is unique to you and won’t be easily guessed by others.
