I have frontier dsl. My laptop is hard wired to modem works fine 10/100 card the pc will not connect it has an onboard realtekl and a pci card....i bought a dlink 10/100 tried all the cards. The settings are all the same as I can tell. I tried contacting frontier they said it was the modem and (modem works on laptop) at one point I had connection then tried a few things like ipconfig a release and now there is no connection. I unistalled then becasue it is an old computer tried to install os and now I still can not get connected. m I missing something. Laptop is xp and the pc is now running windows. I can not activate the windows until I can get connected...thank you for your hlep
