conflicting problems

[Luis Montejano, Jr.]

I'm trying to install a Netgear FA311 pic card and when I install it it will cause my dsl modem to go out. My dsl modem is from actiontec. When the network card is installed I get a yellow exclamation point on the dsl network adapter saying "device is not present, not working or doesn't have all drivers installed." Yet the network card has no conflicts. If I remove the card then the modem works perfectly. I need this to work so I can connect to another pc. Thanks
