It might even be someone who you shared your password with in the past. In most cases, it's probably just someone who needs a WiFi connection. This leads to a common question: 'How do I see who’s on my WiFi?' While sharing your WiFi with a stranger may seem unlikely, harmless, or both, doing so can drain your bandwidth, slow your connections, and, if you have multiple devices set up to share access on your network, it is even possible that your secret guest could access that information too.
Is your internet acting funny? Have your connections slowed down? Or are you just worried that someone may have access to your WiFi network? These are all good reasons to do a quick check of your WiFi connections and, if necessary, beef up security to keep unknown entities from hogging your bandwidth.
