Your problem is a pretty simple one. You have a network card (NIC) that isn't among the stock set of drivers supplied with Windows. So, since it's a Dell, just pop in the drivers and utilities CD that came with the system, select your model, and install the network card drivers.
The 1394 network adapter you see, isn't really a network adapter. It's a Firewire port, which is like a faster version of USB that's sadly underused. You can set all the TCP/IP settings you want on that thing, unless the DSL modem is connected to it, it won't make a bit of difference.
If you're one of the many unfortunate souls who is saddled with a USB DSL modem, or even an internal PCI ATM card, you'll need to install the drivers for that specific connection option. A CD with such should have come with the DSL modem.
In short, the notion that Windows has this massive catalog of drivers that magically supports virtually every piece of hardware under the sun is a bit of a misnomer. Most of these drivers are *NOT* included with and *NOT* installed for you with the stock XP install. It's up to you to add these later. That's why you're given those installation CDs with hardware and new computers. You're problem will be solved by installing the requisite drivers and then making the necessary configuration changes.
I recently reformatted my hard drive and reinstalled Win XP. It all worked very well, except that I can no longer set up an Internet connection.
My computer manufacturer refuses to help because they say it's not a hardware issue. Microsoft refuses to help because I reinstalled the operating system My ISP refuses to help because they think it's a Windows problem.
I connect to the net (or used to) via Earthlink DSL. My computer is hard-wired to a standard DSL modem, which in turn in connected to a wireless router. The router and the modem have nothing to do with the problem. I am in fact posting this email with my laptop which is connected to the net via a wireless connection -- so it's clearly working just fine.
I believe that when I reinstalled the Win XP operating system, I did not install some files or drivers from the other installation CDs that came with the computer. I believe there are either some necessary files missing or there are some settings I have not properly set. When I go into Network Connections, the only icon I see is a 1394 Net Adapter, which I never ever saw before when my computer was connecting perfectly to the net. My TCP/IP properties are exactly right.
Anyway, any help you can give me would be much appreciated. Please let me know if I need to supply any more info.
