What is WiFi and how does it work?
WiFi, short for Wireless Fidelity, is a technology that allows electronic devices to connect to the internet or communicate wirelessly within a specific area. It uses radio waves to transmit data between a router and devices like smartphones, laptops, and smart home appliances. This wireless communication usually relies on standards set by the IEEE 802.11 family of protocols.
When a device wants to connect to WiFi, it sends a request to the router. The router then acts as a bridge to the internet, facilitating data exchange between the connected devices and the wider web. WiFi networks can be secured with passwords, allowing only authorized users to join and making it essential to periodically check for unauthorized devices on your network.
How can I see who is connected to my WiFi?
To check who is connected to your WiFi network, you can log in to your router’s settings. This is typically done by typing the router’s IP address into a web browser. Common addresses include 192.168.1.1 or 192.168.0.1. After entering the IP address, you’ll need to input your admin credentials—this is often printed on the router or set during initial configuration.
Once logged in, look for sections labeled “Connected Devices,” “Attached Devices,” or “Client List,” depending on the router model. This will display a list of devices currently connected to your network, along with their IP addresses and device names, which helps you identify any unfamiliar devices.
