Re: 82567LM keeps showing disconnect in event log

My machine shipped with 11.0.41.250 which apparently was upated by installing Dell R234067 at the factory. I believe that I clicked on "Roll Back Driver" and 10.5.1.0 appeared. It works perfectly with Windows 7 Professional, 64bit.

Since the driver versions you listed are newer than what I started out with, you my not be able to roll back to 10.5.1.0 as I did. Hopefully you can find it somewhere. I would image the machine first just in case.

Version 11.0.41.250 was disconnecting constantly. Accessing the network caused the "connecting" animation to appear over the network Icon in the tray. After 5 seconds or so it was good to go until the next time usually after a period of inactivity, thus the power management theory.

I may be pushing progress backwards with this reply but my disconnect problem was resolved almost a year ago. There was a theory going back then that it had to do with power management. As I recall, the 82567LM-3 driver shipped with my Dell Optiplex 780 / Windows 7/64 had limited control of power management options. The previous version, 10.5.1.0, dated 10/21/2008 did. I rolled back to that drver and haven't had a disconnect since. "Allow the computer to turn off this device to save power" is not checked.

I may have some progress to report on my Windows 7 Professional Optiplex 780 (Q45 chipset). I rolled back the driver to Microsoft version 10.5.1.0. This was suggested some time back on this thread so I gave it a try. Much to my surprise, the driver is already on my machine and was the last item on the list when I "Browsed my computer for driver software".

The bad news is that it behaved just like before but without the error messages this time. Upon waking up from sleep mode, the connectivity was extremely slow. The good news is that this driver has a power management option that can be unchecked to prevent the OS from powering down the "device". With the power-down option disabled, the disconnect problem seems have been resolved!

Still happy with the new driver?

I must admit that I've been lurking on this tread for some time and I though it was time to put in my $.02. I have a Dell Optiplex 780 with a Q45 chipset. This computer was delivered on December 31 with Windows 7 / 64 factory installed.

Event viewer is filled with e1kexpress entries "Intel(R) 82567LM-3 Gigabit Network Connection Network link has been disconnected" messages. Current driver is version 11.5.4.0

The issue ranges from an annoyance to a almost complete loss of connectivity. The computer is set to "idle" at 30 minutes where the display is shut down and the CPU is allowed to go to to 5%. This is basically the Dell "Balanced" setting for power savings. Upon wakeup from this mode, the NIC re-establishes a connection and logs a warning. No big deal. I see an indication in the "tray" that the network is re-connecting and 5 seconds later everything is up and running again. Interestingly, the computer is receiving Email during the power reduction but apparently can't seamlessly wake up again without glitching the NIC.

At 2 hours of no activity, the computer will go into standby. Wake-up is via keystroke. At this point, the computer will wake up with little or no connectivity. Browsing the Internet is just about as fast as a 1200 baud modem although the NIC status reports 100mb. Simply disabling the LAN adapter and re-enabling the LAN adapter restores the computer to full connectivity.

What I've done: The computer is connected to an Actiontec Router which is included with Verizon Fios. I've re-configured the router and NIC for a fixed IP with auto-negotiation turned off. In the device manager, all 3 "Wake on LAN" features are un-checked. VLAN is disabled. None of these changes produced any improvement.

I hope there is clue in here somewhere. I also have a Optiplex 760 with Windows XP using a 82567LM driver dated June 2008 that has performed flawlessly. It makes me wonder if I should be rolling back the driver or moving forward.
