Find out for sure! Log into your router by typing it’s IP address into the browser address bar. If you do not know it already, simply go to Start, then Run/Search, type in cmd, then ipconfig. Look under Local Area Connection next to Default Gateway. Once you have gotten into your routers admin console, look for a tab related to devices. Under this tab you will find all devices currently connected to you wireless. If you see any device you do not recognize, it is time to change/setup a password and turn off your SSID broadcast. this won’t block everyone trying to use your Wi-Fi but it is certainly a step in the right direction. If it seems overwhelming to do this yourself, contact EZ-IT and we can take care of it for you!
