Troubleshooting
Using the indicator lights (LEDs) to Diagnose Problems
The LEDs are useful aides for finding possible problem causes.
Power LED
The Power LED does not light up.
STEP
Make sure that the 4GM3W power adaptor is connected to the device and plugged in to an appropriate
1
power source. Use only the supplied power adaptor.
2
Check that the 4GM3W and the power source are both turned on and device is receiving sufficient power.
3
Turn the 4GM3W off and on.
4
If the error persists, you may have a hardware problem. In this case, you should contact technical support.
Web Configuration
I cannot access the web configuration pages.
STEP
Make sure you are using the correct IP address of the 4GM3W. You can check the IP address of the
1
device from the Network Setup configuration page.
Check that you have enabled remote administration access. If you have configured an inbound packet
2
filter, ensure your computer's IP address matches it.
Your computer's and the 4GM3W's IP addresses must be on the same subnet for LAN access. You can
3
check the subnet in use by the router on the Network Setup page.
If you have changed the devices IP address, then enter the new one as the URL you enter into the
4
address bar of your web browser.
The web configuration does not display properly.
STEP
Delete the temporary web files and log in again. In Internet Explorer, click Tools, Internet Options
1
and then click the Delete Files ... button. When a Delete Files window displays, select Delete all
offline content and click OK. (Steps may vary depending on the version of your Internet browser.)
CORRECTIVE ACTION
Login Username and Password
I forgot my login username and/or password.
STEP
Press the Reset button for ten seconds, and then release it. When the Power LED begins to blink, the
defaults have been restored and the 4GM3W restarts.
1
You can now login with the factory default username and password "admin" (without the quotes)
It is highly recommended to change the default username and password. Make sure you store the
2
username and password in a safe place.
S CORRECTIVE ACT
WLAN Interface
I cannot access the 4GM3W from the WLAN or ping any computer on the WLAN.
STEP
If you are using a static IP address for the WLAN connection, make sure that the IP address and the subnet
1
mask of the 4GM3W and your computer(s) are on the same subnet. You can check the routers
configuration from the Network Setup page.
