WiFi router is a crucial networking device that enables wireless connectivity within a limited area. It connects to your modem, distributing internet access to multiple devices like smartphones, laptops, and smart gadgets. Routers use radio waves to create a local network, providing seamless internet access. They come in various speeds (like 802.11ac or 802.11ax), have security features like WPA3, and may offer dual-band or tri-band options for better performance. Routers often have multiple Ethernet ports for wired connections and can be managed through web interfaces or mobile apps. Essential for modern connectivity
