Frequently Asked Questions

ADSL2MUE Modem with USB and Ethernet

Does the Gateway support any operating system other than Windows 98SE, Windows Millennium,

Windows 2000, or Windows XP?

Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of

any non-Windows operating systems.

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 or half duplex mode, 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 or www.linksys.com for more information.

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

Reset the Modem 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 Modem firmware upgrades?

All Linksys firmware upgrades are posted on the Linksys website at www.linksys.com/international, where they

can be downloaded for free. To upgrade the Modem’s firmware, use the Administration tab of the Modem’s web-

based utility. If the Modem’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 Modem function in a Macintosh environment?

Yes, but the Modem’s setup pages are accessible only through Internet Explorer 5.0 or Netscape Navigator 6.0 or

higher for Macintosh.

I am not able to get the web configuration screen for the Modem.

What can I do?

You can set your PC to a static IP Address.

Is the Modem cross-platform compatible?

Any platform that supports Ethernet and TCP/IP is compatible with the Modem.

How can I check whether I have static or DHCP IP Addresses?

Consult your ISP to obtain this information.

Can the Modem act as my DHCP server?

Yes. The Modem has DHCP server software built-in.
