Network Doesn't Connect on Startup

[Stangs55]

Just reinstalled Windows 7 x64.

ASUS P6X58D Premium mobo
Onboard Marvel Yukon 88E8056 PCI-E gigabit ethernet
ASUS RT-N56U Router

All drivers and firmware completely updated.

The problem is that 75% of the time I either cold boot into Windows or awake from sleep, the card does not connect to the network. No IP. No gateway. No nada. If I open up my adapter preferences, then disable the Marvel network adapter, then re-enable it...it will connect to the network/internet and work fine. That is until it goes to sleep or shuts down. Odd thing though, is that it only does this 75% of the time...the other times it connects just fine.

Dr. Google didn't help.

Help?!

There are alot of possible failures here.

Are there any other computers on the network, and do they exhibit the same behavior? also consider if these other computers are connected to the router via ethernet or wifi.

Second thing I would try is Ubuntu live disk 11.04 to rule out a software/driver issue.

If there are no other ethernet connected systems exhibiting issues and the problem arrises in Ubuntu as wel as Windows I would have to say the issue is with the NIC on your X58 board.

One possible work around is to not use DHCP. You can leave your DHCP server enabled on your ASUS router but statically address your system so that it does not have to get an address from the router.

Thanks for the quick reply.

This is the only wired computer on the network, but the wireless ones connect fine. And I've already tried setting the computer to a static IP...no dice. Honestly, I'm worried it's a hardware problem on my mobo at this point...but it just seems like such an odd way to manifest itself since everything else works fine (including the adapter when it's actually connected).

I'll give the Ubuntu thing a try if I can't find a solution soon...

Doesn't sound off the wall to me as that was one of the first things I did...and have repeated it several times since then.
