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).
You can find the Admin Username and Password printed on the sticker attached to the side, back or bottom of the modem.
CAUTION!Do not remove or lose your modem sticker, which includes your default admin username and password. These preset credentials cannot be retrieved, and your modem could become unusable without them.
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.
