TROUBLESHOOTING
Use this section to solve common problems with the CGN2 and your network.
Problem:
None of the LEDs Turn On
The CGN2 is not receiving power, or there is a fault with the device.
1
Ensure that you are using the correct power adaptor.
Using a power adaptor other than the one that came with your CGN2 can
damage the CGN2.
2
Ensure that the power adaptor is connected to the CGN2 and the wall socket (or
other power source) correctly.
3
Ensure that the power source is functioning correctly. Replace any broken fuses
or reset any tripped circuit breakers.
4
Disconnect and re-connect the power adaptor to the power source and the
CGN2.
5
If none of the above steps solve the problem, consult your vendor.
Problem:
One of the LEDs does not Display as Expected
1
Ensure that you understand the LED’s normal behavior (see
LEDs
on page
18
).
2
Ensure that the CGN2’s hardware is connected correctly; see the Quick
Installation Guide.
3
Disconnect and re-connect the power adaptor to the CGN2.

If none of the above steps solve the problem, consult your vendor.
Problem:
I Forgot the CGN2’s IP Address
1
The CGN2’s default LAN IP address is
192.168.0.1
.
2
You can locate the CGN2’s GUI by entering the LAN domain suffix into your
browser’s address bar (on a computer connected to the LAN). The default LAN
domain suffix is displayed in the
WAN/LAN
>
IP
screen’s
Domain Suffix
field.
See
The IP Screen
on page
47
for more information.
3
Depending on your operating system and your network, you may be able to find
the CGN2’s IP address by looking up your computer’s default gateway. To do
this on (most) Windows machines, click
Start
>
Run
, enter “cmd”, and then
enter “ipconfig”. Get the IP address of the
Default Gateway
, and enter it in your
browser’s address bar.
4
If you still cannot access the CGN2, you need to reset the CGN2. See
Resetting
the CGN2
on page
25
. All user-configured data is lost, and the CGN2 is returned
to its default settings. If you previously backed-up a more recent version your
CGN2’s settings, you can now upload them to the CGN2; see
The Backup
Screen
on page
52
.
Problem:
I Forgot the CGN2’s Admin Username or Password
1
The default username is
cusadmin
, and the default password is
password
.
2
If the default username and password do not work, you need to reset the CGN2.
See
Resetting the CGN2
on page
25
. All user-configured data is lost, and the
CGN2 is returned to its default settings. If you previously backed-up a more
recent version your CGN2’s settings, you can now upload them to the CGN2;
see
The Backup Screen
on page
52
.
Problem:
I Cannot Access the CGN2 or the Internet
1
Ensure that you are using the correct IP address for the CGN2.
2
Check your network’s hardware connections, and that the CGN2’s LEDs display
correctly (see
LEDs
on page
18
).

3
Make sure that your computer is on the same subnet as the CGN2; see
IP
Address Setup
on page
21
.
4
If you are attempting to connect over the wireless network, there may be a
problem with the wireless connection. Connect via a
LAN
port instead.
5
If the above steps do not work, you need to reset the CGN2. See
Resetting the
CGN2
on page
25
. All user-configured data is lost, and the CGN2 is returned to
its default settings. If you previously backed-up a more recent version your
CGN2’s settings, you can now upload them to the CGN2; see
The Backup
Screen
on page
52
.
6
If the problem persists, contact your vendor.
Problem:
I Cannot Access the Internet and the DS and US LEDs
Keep Blinking
Your service provider may have disabled your Internet access; check the
Cable
>
System Info
screen’s Network Access field (see
The System Info Screen
on page
33
).
Problem:
I Cannot Connect My Wireless Device
1
Ensure that your wireless client device is functioning properly, and is configured
correctly. See the wireless client’s documentation if unsure.
2
Ensure that the wireless client is within the CGN2’s radio coverage area. Bear in
mind that physical obstructions (walls, floors, trees, etc.) and electrical
interference (other radio transmitters, microwave ovens, etc) reduce your
CGN2’s signal quality and coverage area.
3
Ensure that the CGN2 and the wireless client are set to use the same wireless
mode and SSID (see
The Setup Screen
on page
86
) and security settings (see
The Access Control Screen
on page
93
).
4
Re-enter any security credentials (WEP keys, WPA(2)-PSK password, or WPS
PIN).
5
If you are using WPS’s PBC (push-button configuration) feature, ensure that you
are pressing the button on the CGN2 and the button on the wireless client within
2 minutes of one another.
