Invisible Network Card?!?

I was connected to the internet via my DSL modem a few days ago and everything was working fine. However, today all of a sudden my internet does not work. I was trying to determine the cause of the issue and got an error message that my computer does not have a network card (which it obviously does as it's on the mobo). I checked device manager and do not see a network card listed (but it does show my 1394 card). I don't know if my network card is damaged? or maybe it's got some sort of driver issue? (although I ran the new hardware wizard and it did not find any new hardware). Any suggestions are greatly appreciated (OS = XP Media).

    Unfortunately, this did not work... it was enabled in the BIOS, but not present at all in device manager. Correct me if I'm wrong, but the onboard NIC might be toast... although it's cheap to buy a new one.

There must be a motherboard failure at the network adapter, because if there is non showing, even with an exclamation mark then there is according to XP no network adapter fitted. Go into the bios (press F2 or Del on start up) and when in the cmos settings, go to advanced and look at the harware menu; and in there should be your onboard network adapter listed as either enabled or dissabled, if dissabled enable it, if not showing at all then there is a motherboard fault, as even if the motherboard driver wasnt working XP's own default driver would see it. all is not lost though because if you don't see it listed in the bios you can fit a PCI ethernet card very easily and cheaply which will fit in one of your spare PCI slots.

Unplug both your DSL/Cable Modem, and the Router from power. Wait 30 seconds. Plug in power to DSL/Cable Modem only, and wait for it to connect. then plug in power to Router, and wait for it to start up. Give it about 1 min. If the lights are still not on, you may need to reconfigure your router. If this does not work, connect your cable/DSL modem to your computer directly, and power cycle it again. Once it is online, check to see if you can get online, if you cannot, contact your internet service provider, as you have ruled out a problem with the router.

Some ISPs (Internet Service Providers) limit you to *ONE* unique computer connected through the cable-modem (or DSL-modem).
Turn the cable-modem off.
Turn the router off.
Connect the cable-modem to the router, via an Ethernet cable to the 'WAN' port on the router.
Turn the cable-modem on.
Turn the router on.
Connect, via an Ethernet cable, from one of the 'LAN' ports on the router to your computer.
Restart your computer.
You should be OK.
If not, telephone your ISP, and get them to trouble-shoot from "their" end towards your end.

you need to configure the dsl modem to be on bridge mode after you did it successfully. that is the time you configure your d-link for you to connect to the internet.
call first your ISP to configure the modem to Bridge mode after that call your manufacturer of the dlink for them to configure your connection

Check to see if you are losing the DSL or Internet light on the modem when you lose your onnection. If so, then check with your IP provider, that may be the problem.

Lost internet connection


Change the calbe from the router to the dsl modem. Make sure you check labels on the rear of these devices to make sure the connections go where indicated. Is there and ethernet light on your modem. If that is on then the connection is made. Also check if the DSL modem works directly connected to the pc.
