To enter the gateway Web interface (WebUI), type http://192.168.1.1 into the URL field of your Internet browser.
Use the following login information when prompted for authentication:

After you login, you will be prompted to change your password for security reasons. The new password must contain at least 8 characters, including at least one uppercase letter, one lowercase letter and one digit. This step is mandatory and you will not be able to interact with the router's WebUI before you change the password.
When you change the router's password, the Configuration Wizard will start. The Configuration Wizard is a tool used to setup some of the router's main operating parameters.
Go to the Status → Network page and pay attention to the Signal Strength indication. To maximize cellular performance try adjusting the antennas or changing the location of your device to achieve the best signal conditions (you can find information on signal strength recommendations here).
