Basic Functioning
After you turn on power to the router, the following sequence of events should occur:
1.
When power is first applied, verify that the Power LED is lit.
2.
After approximately 10 seconds, verify the following:
a.
The Power LED is still solid green. An amber LED indicates that the unit has failed its
power-on self-test (POST).
b.
The Internet Port LED is lit.
c.
The Wi-Fi LED is lit. The Wi-Fi radio is on by default.
d.
The Ethernet LAN Port LED is lit when any local ports are connected.
If a LAN port’s LED is lit, a link has been established to the connected device. If a
LAN port is connected to a 100 Mbps device, verify that the port’s LED is green. If the
port is 10 Mbps, the LED is amber.
e.
The Ethernet WAN Port LED is lit when the router is connected to a wired modem.
f.
The Signal Quality LED is lit when the router has detected a mobile broadband
signal.
A blue LED indicates excellent coverage.
A green LED indicates good coverage.
An amber LED indicates marginal coverage.
If any of these conditions does not occur, refer to the following table.

Troubleshoot Access to the Router Main Menu
If you are unable to access the router main menu from a computer on your local network,
check the following:
If you are using an Ethernet-connected computer, check the Ethernet connection
between the computer and the router as described in the previous section.
Make sure your computer’s IP address is on the same subnet as the router. If you are
using the recommended addressing scheme, your computer’s address should be in the
range of 192.168.0.2 to 192.168.0.254.
Note:
If your computer’s IP address is shown as 169.254.x.x:
Recent versions of Windows and Mac OS generate and assign an
IP address when the computer cannot reach a DHCP server. These
autogenerated addresses are in the range of 169.254.x.x. If your IP
address is in this range, check the connection from the computer to
the router, and reboot your computer.
If your router’s IP address was changed and you do not know the current IP address,
clear the router’s configuration to factory defaults. This procedure sets the router’s IP
address to 192.168.0.1. This procedure is explained in
Restore the Default Configuration
and Password
on page 103.
Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click
Refresh
to be sure that the Java applet is loaded.
Try quitting the browser and launching it again.
Make sure that you are using the correct login information. The factory default login name
is
admin
, and the password is
password
. Make sure that Caps Lock is off when entering
this information.
If the router does not save changes you have made in the web management interface, check
the following:
When entering configuration settings, be sure to click the
Apply
button before moving to
another screen or tab, or your changes are lost.
Click the
Refresh
or
Reload
button in the web browser. The changes might have
occurred, but the web browser might be caching the old configuration.

Troubleshoot Your Connection
Check these possible sources of trouble if you are having difficulty connecting to or browsing
the Internet.
Connecting to the Internet
If unable to connect to Internet, check the following:
1.
The Internet account is active.
If you have not inserted the included 4G LTE SIM card into the SIM card slot on the back
of the router yet, do so now.
2.
Wireless broadband coverage is available where the unit is located.
3.
Access the router main menu to verify that the broadband settings are correct. Check with
your ISP if you are unsure.
4.
Check the location of the router.
a.
Move the router closer to a window for better access to the Internet signal.
A blue Signal Quality LED indicates excellent coverage.
A green Signal Quality LED indicates good coverage.
An amber Signal Quality LED indicates marginal coverage.
An unlighted Signal Quality LED indicates no coverage.
b.
Maintain recommended minimum distances between the router and household
appliances to reduce interference (see
Interference Reduction Table
on page 112).
