Connecting a Router to Wi-Fi involves setting up a wireless network so your devices can access the internet. First, connect the router to your modem using an Ethernet cable, then power it on. Once the router is running, use a computer or mobile device to connect to the default Wi-Fi network name (SSID), usually printed on a label on the router. Open a web browser and enter the router’s IP address to access the setup page, or use the manufacturer’s app. Follow the setup instructions to configure your Wi-Fi name and password. After saving the settings, reconnect your devices to the new network. This process enables wireless internet access throughout your home or office.
