Introduction and Hardware Overview 1 ® This manual is for the following NETGEAR LTE Modem LB1120 and LB1121 models: • LB1120-100NAS. Data model with band support for the North America region. • LB1121-100NAS. Data model with Power over Ethernet (PoE) and band support for the North America region.
LTE Modem LB1120 and LB1121 Introduction The NETGEAR LTE Modem LB1120 and LB1121 models, in this manual referred to as the modem, can provide broadband data services to areas where wired Internet is not readily available or is difficult, costly, or time-consuming to install. The modem uses existing 4G LTE mobile networks with automatic fallback to 3G mobile networks to provide broadband data services.
LTE Modem LB1120 and LB1121 Package Contents Your package contains the modem, an Ethernet cable, and a power adapter. Figure 1. Package contents Install the Micro SIM Card A micro SIM card (that is, a 3FF SIM card) might be preinstalled in the modem or you might need to obtain a micro SIM card and install it yourself. To obtain a micro SIM card, contact your mobile broadband Internet service provider. If you want to use a nano SIM card (that is, a 4FF SIM card), an adapter is required. Figure 2.

Get Started 2 This chapter describes how to connect to the modem. To get started, you do not need to configure the mobile broadband connection.
LTE Modem LB1120 and LB1121 Internet Connection Over Mobile Broadband By default, when the modem powers up with a SIM card installed, it automatically searches for and connects to your network 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.
LTE Modem LB1120 and LB1121 Connect a Computer to the LAN Port of the Modem You can add a single computer to the Ethernet local area network (LAN) of the modem. To connect a computer to the Ethernet LAN of the modem: 1. Attach one end of the Ethernet cable that came in the product package to an Ethernet port on your computer. 2. Attach the other end of the cable to the Gigabit Ethernet LAN port on the back panel of the modem.
LTE Modem LB1120 and LB1121 a. In the Sign In field, enter the modem’s admin password. See the modem label for the default password. Note 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. For more information, see Change the Modem Password on page 38. b. If you do not want to enter your password each time that you access the modem’s web pages, select the Remember me check box. c. Click the Sign In button.
LTE Modem LB1120 and LB1121 If you cannot log in to the modem or your browser does not display the Dashboard page, check the following: • Make sure that the computer, router, or WiFi router is connected to the LAN Gigabit Ethernet port of the modem. • Make sure that your browser does not cache the previous page by closing and reopening the browser.
Manage the Modem LAN Settings This chapter describes how to manage the LAN settings that the modem provides.
