Ethernet adapter problem

9 months ago I bought the asus motherboard and 3 things don't work... .1. the Ethernet adapter dosn't work (the computer can't find my modem even though it is all connected propally and both the speed and connection lights (on either side of the port itself) are on. .2. I try and connect the case headphones attachments to there respective things on the motherboard and they don't work. .3. the audio ports on the motherboard don't work (the ones coming out of the back of the case [not the sound card ones]).

I recently reformatted my brother's PC running this motherboard, and I have a similar issue with the nic. I get all connect lights to my router and from the card itself, and I'm online now on my computer on the same router. Have gone thru all the restarts and resets, have attempted to install drivers for it, several times, it won't take the drivers. I don't know why, I run the driver install (both from the mobo CD, and some I've downloaded from this machine and moved to the old one via a USB flash drive) when using ipcfg from cmd promt it still lists nothing, which tells me the stupid mobo just won't recognize any of the drivers I'm feeding it. Still working on a work around *sigh*

What it sounds like is that you didn't install the drivers. In order for sound and ethernet to work, you must first boot up the CD that came with the motherboard and install the Drivers.

There is not enough information here to be able to identify to a great degree of accuracy what the true problems could be, but I will take a stab anyway. Is it safe to assume that the current configuration has been working in all 3 aspects during the previous 9 months? If this is the case, it is possible that your modem (if it is a cable modem) may need to be reset to acquire a new address. The activity and collision LEDs do not necessarily tell you that you are connected. The headphones problem...possible that you inadvertently disconnected the motherboard connector and placed it on incorrectly while researching one of the other issues? This could also be the case for the audio connector. Double (and triple) check all cable connections to the motherboard to ensure they are in the correct orientation and location. If the above is insufficient feel free to post more detail, such as did it previously work, did you previously install any new hardware and/or software, thunderstorms in the area recently, changes at your ISP? Good luck.

This is Dell Support >XPS 400 desktop computer > Service Manual,

1) Work on a table. Computer off, and unplugged from power, open the computer case.

(Removing the Computer Cover, in the list)

2) Follow Anti-Static precautions.

[Anti-Static Precautions:

Your body carries Static electricity.
Static will fry out (Short Circuit) the delicate hardware components, inside a computer.

To relieve your body of Static, TOUCH the metal frame of the open computer case.
Should you leave your computer in the middle of working on it, upon your return be sure to Touch the metal frame again ]

3) View the motherboard inside your computer.
(The motherboard is also referred to as the Mainboard, {Proper speak}, and System Board)

Technical Overview > System Board Components,

Viewing the illustration of the motherboard, the Ethernet Adapter Card example I gave above, would go in either one of the PCI expansion slots.

These are white in color, and in the illustration are labeled - PCI Card Connectors.

If there is already an adapter card installed in both PCI expansion slots, then see if the PCI Express x1 expansion slot is open.

In reality, PCI Express is a better technology than PCI.

Shown on the motherboard as PCI Express x1 Card Connector.

This is an example of an Ethernet Card, (Ethernet Adapter Card), that uses the PCI Express x1 expansion slot,

The reason I have suggested buying, and installing an Ethernet Adapter Card is threefold.

1) You may have your Ethernet cable plugged into the Ethernet port of the computer,

[Number 3 - Network Connector],

and the built-in Ethernet is no good.
Reinstalling drivers May help, but the above is a sure thing.

2) You have an Ethernet Adapter Card plugged into one of the PCI slots, or the PCI Express x1 slot, and the Ethernet adapter card is no good.
They do go bad, and are economical to replace.

3) There was an Ethernet Adapter Card installed previously, but taken out before you received the computer.

first check for all the drivers in the device manager.... if every thing is perfect in driver side, then check if the ethernet/ lan is enabled....
then check is the light in the ethernet adapter is lit, when you plug any ethenet cable in it... still if it is not working, then finally try to update the latest driver for the ethernet controller.... if nothing works, then buy an pci ethernet card and use it..... you can also buy external cards like usb to ethernet converter... even belkin manufactures usb to ethernet controller....

Looking for a compatible Driver for my Ethernet connection

Open up device manager> double click on the unknown device> go to the details tab> in the drop down choose hardware id> google the alpha numeric code on the first row before the & symbol (ex- PCI\VEN_14E4)

That will give you the make of the ethernet adapter you have on the pc. Once you have it installed you can patch up the wireless as it works on the network adaptor base which generates the ip address.
