APPENDIX A

TROUBLESHOOTING

Check the following troubleshooting points before contacting SMC Technical Support.

You Cannot Connect to the Network

•Check the phone and USB cables for wear or loose wires and replace any defective cables if necessary. Make sure the cable is securely attached to the modem’s RJ-11 port and that the modem is connected to your ADSL service provider via an RJ-11 wall socket or splitter.

•If your PPP connection fails to respond, hang up and dial again. PPP may fail to connect when you first dial in due to synchronization problems.

•If the Data LED is off, review the driver installation process to be sure that the driver was correctly installed. Make sure the correct software driver was installed for your operating system. A failed or aborted installation may leave some system files or drivers that interfere with a new installation. If necessary, remove the EZ Connect ADSL USB Modem driver, and try reinstalling it.

You Cannot Connect to the Internet

•Click the Network icon in the Control Panel and enter the required TCP/IP settings specified by your Internet Service Provider (ISP). Then reboot your computer to enable the new settings.
