All wireless routers come with a default name which is assigned by the manufacturer or internet service provider. To reduce the chances of hacking, change it to a name that is unique to you and won’t be easily guessed by others. The default ID is called a “service set identifier” (SSID) or “extended service set identifier” (ESSID). You can also make the SSID and ESSID hidden. This is another simple step that can help prevent attacks on your router.
