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).

Re: Invisible Network Card?!?
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.

If you don't reset the modem after connecting the router, the modem is still trying to send data to the MAC address of your PCs network card. You need to disconnect power from everything, then power up the router first. Once the LEDs on the router settle down, power up the modem. Once the modem's LEDs have settled down, power up the computer. You should now be able to access the internet through the router.
The only time this won't resolve the issue is if the PPPoE negotiation is being done by the PC and not programmed into the modem itself. This is almost unheard of with modern DSL and ADSL modems today, but if that is the issue, you will need to contact your ISP for the information you will need to program the router to do the PPPoE login through the modem and reconfigure the computer to not do the PPPoE authentication any more.
Here are a few things to try: - Remove all the devices plugged into the netgear and leave only the TV and Internet connection - Swap the cable for the TV Internet connection - Try a different port on the netgear - Monitor the activity lights on the netgear
Are you still able to connect to netfix via a computer?
The difference between a Lsn Card and a modem are
this - A Lan card is a card that you slide into the side of a laptop
and it can allow you the ability to get onto a network wirelessly. A Lan
card for a PC allows a Lan connection by way of a CAT 5 cable that will
allow you to get onto the internet or if a crossover cable is attached
to your pc to another you are directly connected to the network. A
modem is a piece of hardware that is installed into a slot in the PC
that will allow you the ability to get onto the internet by attaching a
phone line to it through the RJ 11 jack (which it comes with 2 rj11
jacks on it).
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
I bet you are using the phone modem that canme in your machine. You need to connect the Network card ( Ethernet Card) and make sure the drivers are working. Find it is System, Hardware, device manager, look for ethernet.
Connection icon and see if the netcard driver is installed.Connect the cat5 cable that was sent to you with the DSL modem box. It chould be a yellow cable... It only fits one way and in a maked plug on the DSL modem and into the network card in the computer. Everything there after should go automatically.
This could even be the Dsl modem loosing internet sync, They will tell you its you're end and thats fine check the modem, it also could be the ethernet cards going into standby Thus turning off the wake on lan feature in bios or other software would provent the card from going to sleep.
i agree with all the above.. it's definately clear as mud how the network is designed and or funtioning. The machines connected to the wireless d-link router.. are they via cat5 inthe wired ports or wireless ? is the server the machine thats connecting to the switch and wiress router and modem? i'd say reset all switches modems routers and machines.. shut them all down.. then fire the cable modem, then the wireless router then the desktop switch then the server, the workstations and the one lonely wireless.. run "ipconfig /all" on all machines and if they aren't all sharing common ips and access, provide the results here for further investigation.
