Ethernet won't wake up after computer sleeps. Asus Z87-Pro running Windows 7 64 bit.

Asus Z87-Pro running Windows 7 64 bit. Downloaded and installed latest bios & drivers. All windows updates installed. After the computer has gone into sleep mode and you wake it up, there is no ethernet connection. I get around it by opening IE and hit the diagnose button when it pops up. The result is always the same. Connection is restored by "resetting network controller".
Any help would be very much appreciated.

Go into device manager and disable sleepmode on your network controller

Thanks for the information however, there is no obvious option to disable the sleep mode.
The closest I can find is "Energy Efficient Ethernet" in the Intel I217-V Ethernet properties dialog but regardless of choice, it makes no difference.
Ethernet still has to be reset manually after sleep mode.

I don't have that option. Under the power management tab, the options are:
Power Saver Options:
Respond to ARP requests without waking system
Respond to NS requests without waking system
Energy Efficient Ethernet
Reduce link speed during standby
Reduce link speed during system idle
Wake on LAN:
Wake on Magic Packet
Wake on Pattern Match
Wake on Magic Packet from power off state
Wake on Link Settings

Just got off the phone with them. Their response was to call Microsoft that it must be a problem with Windows 7. Useless. And I really like Asus MB's too! This is just an aggravating issue to always have to troubleshoot the network connection to get it to re-set after the computer goes to sleep.

I agree, sounds like a driver problem, should be an option to not power down

I agree the option should be there but the original driver and updates came from Asus. You would think they would know what was or was not in the driver they put out with the MB. Since it is an Intel Ethernet controller, I wonder if Intel is where I should go?

I was working fine with standard memory settings in the BIOS.
I changed the XMP settings to take advantage of my faster memory and then started having the same problem.
I changed the XMP settings back to the default, but it didn't resolve, still had no network connectivity coming out of sleep.
I then downloaded the latest PROWinx64.exe driver package from Intel and the problem has not manifested itself in the past two days.

Thanks. I'll give that a try as well.
