Manage Your LTE Modem

To access your LTE modem

Launch a web browser from a device that is connected to the modem.
In the address field of the web browser, enter http://192.168.5.1.
In the Sign In field, enter the default password, and click the Sign In button. See the modem label for the default password.
- While the password that you enter is unique to your modem and is secure, we recommend that you change it to a password that you want to use.

Mobile Broadband Internet Connection

By default, when the modem powers up with a SIM card installed, it automatically searches for and connects to your mobile service provider’s mobile broadband network. This process might take several minutes. The SIM card that is installed determines the mobile broadband network to which the modem connects.

However, if the modem does not automatically connect to the mobile broadband network, the Power LED remains solid amber, and you must contact your mobile service provider to get the access point name (APN) profile information and add and activate a custom APN profile in the modem (see Add and Activate a Custom APN Profile).

Add and Activate a Custom APN Profile

If the modem does not recognize the settings of the installed SIM, contact your mobile service provider to get information about the APN profile that you must use. Use the information that your mobile service provider gives you to configure a custom APN profile.

To add and activate a custom APN profile for a mobile service provider’s mobile broadband network:

Launch a web browser from a device that is connected to the modem.
In the address field of the web browser, enter http://192.168.5.1.
- The limited Dashboard page displays.
To access the full Dashboard page and other pages, in the Sign In field, enter the default password, and click the Sign In button. See the modem label for the default password.
Select Settings > Network > APN.
- The APN page displays.
Click the Add button.
- The New APN pop-up window opens.
Enter the settings for the new APN profile. Use the information that your mobile service provider gave you. If your mobile service provider did not specify some settings, leave the default settings.
Click the Save button.
- The new APN profile displays on the page but is not yet the active profile.
Select the radio button next to the APN profile that you just added.
- The modem now uses the selected APN profile to establish a connection with the mobile broadband network of the mobile service provider.

If you still cannot get an Internet connection, contact your mobile service provider to verify the information for the APN profile.
