Chapter 5: Troubleshooting
If your router is not functioning properly, please refer to the suggested solutions provided in this
chapter. If your problems persist or the suggested solutions do not meet your needs, please kindly
contact your service provider for support.
Problems with the router
Problem Suggested Action
None of the LEDs lit when the router is
turned on
Examine the connection between the router and the
adapter. If the problem persists, most likely it is due
to the malfunction of your hardware. Please contact
your service provider for technical support.
Fail to make fiber connection
Ensure the fiber cable or the mini-GBIC module has
been connected correctly and the fiber cable has
not become damaged or bent. Ensure that you ap-
ply right fiber cable(s) into right port(s) and right SFP
module into right device as well. If these steps do
not resolve the problem, please contact your service
provider for technical support.
You have forgotten your login username
or password
Try the default username & password (Please refer
to Chapter 3). If this fails, restore your router to its
default setting by pressing the reset button for 1~2
seconds.
Problem with LAN interface
Problem Suggested Action
Cannot PING any PC on LAN
Examine the Ethernet LEDs on the front panel. The
LED should be on for the port that has a PC con-
nected. If it does not light, check to see whether the
cable between your router and the PC is properly
connected. Make sure you have first uninstalled
your firewall program before troubleshooting.
