Sometimes a WiFi device won't connect to the WiFi network and you can't find the reason. If you've tried everything else, you can fix the problem by setting up a secondary WiFi network (SSID) with different security settings to connect to the device.
NOTE: Depending on your model, your modem's user interface may appear slightly different from the images below.
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.
14. From here you can choose the default security key/passphrase, or set your own customized key.
15. Select "Apply" to save your changes again. Now your new network should be live and you can connect your device(s) to it by entering the network name and security key created above into the device's WiFi settings.
