Internet Connection Over Mobile Broadband; Connect A Computer, Switch, Hub, Router, Or Wifi Router To The Modem - NETGEAR LB1121 User Manual

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.
Note Even though the modem might connect to the mobile broadband network of the same
service provider each time that you start the modem, the type of mobile broadband
service (LTE, 4G, or 3G) to which the modem connects might differ.
If the modem does not automatically connect to the mobile broadband network after 10 minutes, the Power
LED remains solid amber, and you might need to contact your mobile service provider to get the access
point name (APN) profile information and add (see

Connect a Computer, Switch, Hub, Router, or WiFi Router
to the Modem
By default, the modem functions in Router mode with the DHCP server enabled and IP pass-through (IPPT)
disabled. This means that you can connect multiple devices to the modem, for example, through an Ethernet
switch or hub, and that each device can receive an IP address from the modem.
If you want to connect a router or WiFi router to the modem, change the operation mode of the modem to
Bridge mode, in which IP pass-through (IPPT) is enabled and only a single device can be connected to the
Internet through the modem. (The single device that is connected to the modem is the router or WiFi router,
but depending on the capabilities of the router or WiFi router, you can connect multiple devices to the router
or WiFi router.)
If you want to connect a computer only to the modem, the modem can function either in Router mode or in
Bridge mode.
For information about changing the operation mode of the modem, see
Mode on page 23.
