Network Adapters do not work

There are two ethernet ports back of the computer from the mb. When I plug a cable into either ports the system cannot find the connection to the internet modem. I have checked the BIOS to be sure Net ports are on and I have searched for updated drivers with both the mother board cd and the win xp cd in hardware. The mb has two ethernet drivers, one is NVidia and one is Marvell. The lights on the ports blink and the modem (cable) is good. I have another computer using it and it works fine. My usbD-Link wireless adapter connects to the internet flawlessly. I don't know what more I can do.

I believe the board is on its way out. I purchased a Linksys 10/100 EtherFast PCI Adapter card. I installed it according to directions. Everything went perfectly. With eithernet cable from the network hub connected, the computer detects NOTHING. The connection appears in Network Connections as connected. When I try to connect to the internet, there is no connection. I plug the cable into the motherboard NVIDA port and it does detect the connection as confirmed. Icon appears in display. But, when I try Internet Explorer, all I get is the page cannot be displayed message. Note, I am typing this message on another computer which is connected from the same Lynksys hub as the faulty computer. The hub is therefore good as is the connection to the modem. As I said before, when I use the wireless adapter I can connect everytime. I guess I am going to shopping for a new computer but I am going to wait for Windows 7.

After much frustration etc I repair the network connection problem with my computer. I decided to flash the BIOS from ASUS support website. I flashed the latest file and restarted the computer. Guess what, the system asked for drivers for the NVIDIA network controller. I copied out drivers from my motherboard cd to the install wizard and VOILA! after a reboot I connected the ethernet cable and here I am on the internet relaying the joyfull news. As a further bonus, recall I said the new ethernet card I installed did not work--well it also works now. Amazing!

Glad to see you found a method of happiness. 2 network ports faulty, sorry to hear that. However the linksys card in my opinion is way better than any onboard network nics. Think of it as a upgrade to your system.

Shop for a new board while you wait for windows 7, great deals on newegg.com or your local microcenter store (if you have one near you). I just bought a nice asus board with a quad core processor for 279$

Take care.

Thanks for the checklist to go through the network problems. I had already done most of these points, anyway. When I got the new network card and still no network connection, I knew it had to be a motherboard/BIOS issue. I was very luck the Asus Update worked. Thanks

Oh, the linksys did not work? I read that too fast I guess, "everything went perfectly".. Congrats on solving your issue. Newer bios solved the problem..I wonder what could have happened after working for a while that the ports decided to stop. You did verify they were enabled in bios, so perhaps the bios somehow gotten corrupted. Congrats again!
