Troubleshooting

29.1 Overview

This chapter offers some suggestions to solve problems you might encounter. The potential
problems are divided into the following categories.

l

Power, Hardware Connections, and LEDs

l

LTE Device Access and Login

l

Internet Access

l

Wireless Internet Access

l

Phone Calls and VoIP

l

UPnP

29.2 Power, Hardware Connections, and LEDs

29.3 LTE Device Access and Login

I forgot the IP address for the LTE Device.

Step 1

The default IP address is 192.168.1.1.

Step 2

If you changed the IP address and have forgotten it, you might get the IP address of the LTE
Device by looking up the IP address of the default gateway for your computer. To do this in
most Windows computers, click

Start > Run

, enter

cmd

, and then enter

ipconfig

. The IP

address of the

Default Gateway

might be the IP address of the LTE Device (it depends on the

network), so enter this IP address in your Internet browser.

Step 3

If this does not work, you have to reset the device to its factory defaults, see

RESET Button

----End

I forgot the password.
