Look at the LEDs (lights) on the LTE5121 front panel:
• The POWER light blinks during start-up and stays on once the
LTE5121 is ready.
• The ETHERNET light turns on if the corresponding ETHERNET port
is properly connected and it blinks when there is traffic.
• The WLAN light stays on and green when the wireless LAN is ready.
The light will not turn on if the wireless connection is not activated. It
is blue when WPS configured.
• The LTE/3G light blinks while the LTE5121 is initializes the LTE
connection and stays on after the LTE connection is ready.
• The SIGNAL STRENGTH lights display the LTE connection’s signal
quality. More bars means a better signal.
• The INTERNET light is green when Internet access is available. It
blinks when transmitting data.
• The PHONE lights stay on when your SIP account is registered and
blink if the receiver is off the hook.
If the POWER light does not turn on during start up, turn the LTE5121 off, check
the connections, wait a few seconds and then turn it back on. If the problem
persists, you may have a hardware problem and you need to contact your vendor.

wish to use WPS (Wi-Fi Protected Setup) instead.
1. Right-click the wireless adapter icon in the bottom right of your
computer monitor. Click View Available Wireless Networks.
2. Select the LTE5121’s SSID name and click Connect (A). The SSID
“SecureWirelessNetwork” is given here as an example.
SSID: SecureWirelessNetwork
WPA2-PSK: 7WC3R7TVKWK3R

3. When prompted for a password, enter the (WPA2-PSK) encryption
key from the back panel of the LTE5121 and click Connect.
4. You may have to wait several moments while your computer connects
to the wireless network.
5. You should now be securely connected wirelessly to the LTE5121.
If you cannot connect wirelessly to the LTE5121, check that you selected the
correct SSID and entered the correct security key. Make sure the LTE5121’s
physical WLAN ON/OFF button is set to ON and the WLAN LED is on.

Connect to the Internet
1. Open your browser and go to http://192.168.1.1.
• If your service provider’s LTE login page appears instead of
your default Home page then all you need to do is enter the
login information that you were given and follow the on-
screen instructions. The LTE5121 should then automatically
update itself with the settings that you need to connect to
the Internet.
• If your service provider’s LTE login page does not appear, do
the following:
2. Enter the default username “admin” and password “1234”. Click
Login.
If the login screen does not open, make sure you allow web browser pop-up
windows, JavaScript and Java permissions. Your computer should also be
set to get an IP address automatically from a DHCP server. See your User’s
Guide for more information.
3. If the INTERNET light is off, manually configure the Internet
connection. Click Network Setting > Broadband. If the APN
(Access Point Name) is not the same as what you were given, click
the LTE connection’s Edit icon.

The APN identifies the LTE network to which your LTE Modem connects.
4. Change the APN, IP address and DNS server settings if necessary.
Click Apply.
5. If a PIN code is required, click Network Setting > Broadband > SIM.
Enter it and click Apply.
