4 Trouble-Shooting
This chapter describes how to solve a number of issues that could occur during installation, configuration, and use of the Ericsson W20. More information is available at www.ericsson.com/fwt.
Before you try any of the methods described in this chapter, make sure that the connected cables are securely inserted and that the Power indicator on the Ericsson W20 is green.
If none of the suggested methods solve your problem, you are recommended to:
1.Restart the Ericsson W20.
2.Reset the Ericsson W20 to factory default configuration.
3.Contact your service provider.
To restart the Ericsson W20, click the Restart 
on the System web page. If you cannot access the Ericsson W20 web pages, remove the power cable to disconnect the Ericsson W20 from power and wait a moment before reconnecting the cable.
To reset the settings to factory default, disconnect the Ericsson W20 from power by removing the power cable. Then use a tip of a pen to press the Reset button while reconnecting the power cable. Keep the Reset button pressed for at least 20 seconds.
The factory default configuration contains the original settings of your Ericsson W20. When you install your Ericsson W20 and access the web pages for the first time, the configuration file contains the factory default configuration.
Note: A reset to factory default configuration cannot be undone. If you reset the Ericsson W20 to default configuration, all your previous configuration changes are replaced. If you have previously changed the user name and password, the User Login page will be displayed. You have to login to the web pages with the default user name and password (user in both fields).
