A WiFi router is a device that connects multiple devices to the internet wirelessly. It acts as a central hub, receiving data from your internet service provider (ISP) and distributing it to devices like smartphones, laptops, and smart TVs via WiFi signals. Most routers have several antennas to enhance signal strength and coverage, ensuring stable internet access throughout your home or office. Equipped with security features like firewalls and encryption, routers protect your network from unauthorized access. Many modern routers offer dual-band or tri-band technology to handle multiple devices simultaneously without slowing down. Easy to set up and manage, a WiFi router is essential for creating a wireless network.
