Monitor your router’s data to see if others are using it

If you live in an area with a dense population, you’ll want to be sure there aren’t any bad actors sapping the speed of your Wi-Fi. Virtually all routers can tell you what connections are being used at any given time. Check your router’s configuration page to make sure that only approved users are using your Wi-Fi. If you see a suspicious connection and can’t verify it, you might want to change your Wi-Fi’s security settings.
