Appendix Appendix C Troubleshooting This chapter is intended to help you troubleshoot problems you may encounter while setting up and using the Router. It also describes some common hardware and software problems and gives some suggestions to troubleshoot them. C.1 Diagnostics with the LEDs Most hardware problems can be diagnosed and solved by checking the LEDs on the front panel of your Router.

!"If the PWR/CHK LED is dark

- Make sure the power cord is firmly plugged into the back panel of the router and the other end into an active AC wall or power strip outlet.

!"If the LAN or WAN port LINK/ACT LED is dark

- Make sure your Ethernet cable is firmly plugged into the back panel of the router and the other end into your computer or HUB.

- Make sure you using the correct Ethernet cable on WAN port for your application.

- Make sure your Ethernet board is installed properly in your system by ping the IP address of your PC. A10 Heritage Series ADSL Bridge/ Router Appendix C.2 No respond or active data A11

!"No respond from system configuration server

- Make sure your URL is correct and not conflict with any other device on network. The factory default URL is http://192.168.100.1 . You cannot recall any page or budirectory without password verification. Please do not add any parameter after the IP address. If you changed the LAN IP address, please use the new system configuration server IP you changed. If you forget the IP you changed, you can only reset the configuration to factory default to setup your Router again. Please refer 3.1 Get your Broadband Sharing Router ready to know how to reset the Router configuration to factory default.

- Make sure you are accessing the configuration server through LAN ports. The configuration server can only be accessed through LAN ports, not from WAN port.

- Make sure your configuration PC is in the same subnet which LAN port setup specified or your IP is getting from Router DHCP. Please use IP configuration check to verify your PCs IP address.

- Make sure your LAN port connection is linked and active correctly.

!"Data link is brocken

- If your network is configured correctly, you can share and connect different computers. If the data cannot be accesses through the Router, restart your Router with unplug the power cord. Wait for a while and plug in the power again. The system needs one to two minutes to boot itself up. Please wait until the PWR/CHK LED light steadly and then keep going for further operation.

- Make sure that all devices IPs connected with LAN port, direct connect or through HUBs, should follow the rule of LAN port configuration. Gateway IP is the same as system configuration server and cannot be used by any other device.
