ASROCK X58 Extreme LAN issues

Just built a new PC using an ASROCK X58 Extreme. Using the onboard LAN.

Internet had been up, running and functioning great. Was downloading Vista Updates for days. Fixed an audio issue, rebooted and when she came back up no internet.

When i do a diagnose ad repair i get: This computer does not have a network adapter installed and configured.

CMD>ipconfig gives:

Tunnel adapter Local Area Connecion* 7:

Media State . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . :

Cables, routers and router ports all tested with known good equipment and come out fine.

Uninstalled and reinstalled original drivers with same results.

Newer version of the LAN drivers report "no NIC"

Confused, any help would be appreciated.

Yes, ethernet was still enabled.

Oddly, this appears to have repaired itself after about 8 reboots. Have no idea why it happened.

I had exactly the same case as you, and your solution seemed to fix the problem. Thanks!

[quotemsg=102678,7,522414]By the way, I was just on the ASRock website and noticed that BIOS v1.60 was released on Nov 17. The description of it says, "Enhance LAN connectivity or Fix some LAN loss issues." I'm not sure if that'll fix the problem, but it sure sounds promising.

I've installed the v1.6 update and while the network card does work, it still has issues losing connections. I can't get a download of software from MSDN, and my VPN connections get dissconnected fairly frequently.

I had the same problem. Unplugging the power is one solution but the hassle was not worth it and I have no time with RMA. So I got a $30 something Intel gigabit lan card and smack it to one of the pci. 100% connection. I read that other X58 mobo have the same exact problem not just Asrock.

I found out that the problem is the Intelligent Energy Saver utility that comes with the mobo, i install all the drivers from the CD and when you install the whole thing automatically sets it as default, anyways, that power savings option allows the computer to go to sleep, (which i never use), that causes this whole issue to start with. I took it back to where i got it from, cause only bought it a few months ago, and they told me they can take it back but they have to send it back to Asia to see if they can fix it, it all take a whole month if i get lucky, however this is too much of a hassle for me so just for the sake of it im taking it back cause i can't be bothered trying to fix something that shouldn't have broken in the first place AND its warranty covered so meanwhile i'm buying another one, i guess im picking an american brand this time just because when something brakes they just solve the issue by giving you a new one (no hassle)
