The Wireless Diagnostics tool gives you insights into your WiFi network, including WiFi channels available, specific devices, and access points.
1. Connect a device, such as a computer or tablet, to the internet through WiFi or using an Ethernet cable connected to your modem.
2. Open a web browser and type http://192.168.0.1 into the web address field.
3. Log in to the modem's settings interface (Modem GUI) using your Admin Username and Admin Password. Note that these are different from your wireless network name (SSID) and WiFi password (security key).
Channel Analysis gives you data about available WiFi channels, including non-WiFi noise, noise from other access points, total channel noise, and channel rank. This can help you choose and set the optimal channel.
