I have an old USB DSL modem that I am trying to get to work with Windows 7. It is a CNet CNAD800-EF and the latest official drivers available are for Windows XP.


Is there any way I can find Windows 7 drivers for this DSL modem, or use my Windows XP drivers under Windows 7?

This question came from our site for professional and enthusiast programmers.

Why do you even need the driver CD for a DSL modem? You should be able to configure the modem via an online interface. For instance to access my DSL I go to in my browser and I can login to the device and configure. The modem should be independent of any hardware using it.

Simply connect an ethernet cable from the modem to your PC. Reboot the PC. Then open up your browser and then try some of the typical logins like,, etc..

In any event you dont need driver to configure a modem, there has to be an online interface you can access. Have you tried calling CNET to see if they can forward you a user guide or to ask them how you can configure it via IP? – xXPhenom22Xx Mar 4 '12 at 16:32
nop I didn't call them , there site has a file to download , it only contains the picture of the modem , not the drivers of the modem. – 123Ex Mar 8 '12 at 7:31
Not all DSL modems are attached via Ethernet. Ones that aren't will not have the web interface. This one clearly has no such interface, as documented on the site linked. – Brad Jun 25 '12 at 0:02
