Appendix A: Troubleshooting
Frequently Asked Questions

ADSL Gateway with 4-Port Switch

The web page hangs; downloads are corrupt, or nothing but junk characters are being displayed on the
screen. What do I need to do?

Force your Ethernet Adapter to 10Mbps, and turn off the “Auto-negotiate” feature of your Ethernet Adapter as a
temporary measure. (Please look at the Network Control Panel in your Ethernet Adapter’s Advanced Properties
tab.) Make sure that your proxy setting is disabled in the browser. Check our website at www.linksys.com/
international for more information.

If all else fails in the installation, what can I do?

Reset the Gateway by holding down the reset button until the Power LED fully turns on and off. Reset your DSL
modem by powering the unit off and then on. Obtain and flash the latest firmware release that is readily available
on the Linksys website, www.linksys.com/international.

How will I be notified of new Gateway firmware upgrades?

All Linksys firmware upgrades are posted on the Linksys website at www.linksys.com, where they can be
downloaded for free. To upgrade the Gateway’s firmware, use the Administration tab of the Gateway’s web-
based utility. If the Gateway’s Internet connection is working well, there is no need to download a newer
firmware version, unless that version contains new features that you would like to use.

Will the Gateway function in a Macintosh environment?

Yes, but the Gateway’s setup pages are accessible only through Internet Explorer 4.0 or Netscape Navigator 4.0
or higher for Macintosh.

I am not able to get the web configuration screen for the Gateway. What can I do?

You may have to remove the proxy settings on your Internet browser, e.g., Netscape Navigator or Internet
Explorer. Check with your browser documentation, and make sure that your browser is set to connect directly
and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and then the Connection tab.
Make sure that Internet Explorer is set to Never dial a connection. For Netscape Navigator, click Edit,
Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct connection to the Internet.

What is DMZ Hosting?

Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the Internet. Some applications
require multiple TCP/IP ports to be open. You should set your computer with a static IP if you want to use DMZ
Hosting. To get the LAN IP address, see “Appendix C: Finding the MAC Address and IP Address for Your Ethernet
Adapter.”

If DMZ Hosting is used, does the exposed user share the public IP with the Gateway?

No.

Does the Gateway pass PPTP packets or actively route PPTP sessions?

The Gateway allows PPTP packets to pass through.
