NETGEAR 4G LTE Modem Troubleshoot the Mobile Broadband Internet Connection If your modem cannot access the Internet, check the mobile broadband connection: • Make sure that a SIM card is installed in the modem. SIM cards from other devices do not function in the modem and this SIM card does not function in other devices. For information about inserting the SIM cards, see Install the Nano SIM Card on page 10. • If SIM security is enabled, make sure that you entered the PIN correctly to unlock the SIM card (see Enter the SIM PIN to Enable the Modem to Connect to the Internet on page 57). A locked SIM card prevents the modem from connecting to the mobile broadband network. • Make sure that your mobile broadband account is active. • Check with your Internet service provider to ensure that coverage exists in the area. If no mobile broadband coverage exists, all Signal Strength bars are off. • If only one or two Signal Quality LED bars light, move the modem closer to a window for better access to the mobile broadband signal. • Check to see if your mobile service provider is experiencing network problems. It might not be that the modem cannot connect to the Internet, but rather that your service provider cannot provide an Internet connection. • You might need to add a custom APN profile (see Manage APN Profiles for Mobile Broadband Connections). Contact your mobile broadband service provider. For more information about Internet connection problems, see TCP/IP Network Not Responding on page 97. Obtain an Internet IP Address From Your Service Provider If your modem cannot access the Internet but the Signal Strength LED lights green, see if the modem can obtain an Internet IP address from the mobile broadband service provider. Unless the modem was assigned a static IP address, the modem requests an IP address from the mobile broadband service provider. You can determine whether the request was successful (see View Account Details and Other Details About Your Modem on page 74). Alerts and Troubleshooting 95 User Manual

Troubleshoot the Mobile Broadband Internet
Connection
If your modem cannot access the Internet, check the mobile broadband connection:
•
Make sure that a SIM card is installed in the modem. SIM cards from other devices
do not function in the modem and this SIM card does not function in other devices.
For information about inserting the SIM cards, see Install
the
Nano
SIM
Card
on page
10.
•
If SIM security is enabled, make sure that you entered the PIN correctly to unlock the
SIM card (see Enter
the
SIM
PIN
to
Enable
the
Modem
to
Connect
to
the
Internet
on
page 57). A locked SIM card prevents the modem from connecting to the mobile
broadband network.
•
Make sure that your mobile broadband account is active.
•
Check with your Internet service provider to ensure that coverage exists in the area.
If no mobile broadband coverage exists, all Signal Strength bars are off.
•
If only one or two Signal Quality LED bars light, move the modem closer to a window
for better access to the mobile broadband signal.
•
Check to see if your mobile service provider is experiencing network problems. It
might not be that the modem cannot connect to the Internet, but rather that your
service provider cannot provide an Internet connection.
•
You might need to add a custom APN profile (see Manage APN Profiles for Mobile
Broadband Connections). Contact your mobile broadband service provider.
For more information about Internet connection problems, see TCP/IP
Network
Not
Responding
on page 97.
Obtain an Internet IP Address From Your Service Provider
If your modem cannot access the Internet but the Signal Strength LED lights green, see
if the modem can obtain an Internet IP address from the mobile broadband service
provider.
Unless the modem was assigned a static IP address, the modem requests an IP address
from the mobile broadband service provider. You can determine whether the request
was successful (see View
Account
Details
and

Your
Modem
