What is Wi-Fi, and how does it work?
Wi-Fi is a technology that allows electronic devices to connect to a wireless local area network (WLAN), enabling them to communicate with each other and access the internet without the need for physical cables. It operates using radio waves, transmitting data between a wireless router and connected devices like smartphones, tablets, and computers, allowing seamless internet access.
Wi-Fi networks function within specific frequency bands, usually 2.4 GHz and 5 GHz. The 2.4 GHz band offers broader coverage but may have slower speeds due to congestion, while the 5 GHz band supports faster speeds with a shorter range. The router acts as a hub, broadcasting signals to connected devices, which can then send and receive data packets, facilitating internet browsing, streaming, and file sharing.
How can I see who is connected to my Wi-Fi network?
To check who is connected to your Wi-Fi network, start by accessing your router’s settings through a web browser.
