Intel 82567LM-3 network card on Lenovo desktops disconnecting

MortensonIT asked
Good afternoon.

On our Lenovo Thinkcentre desktops (sorry, I don't have the exact model), the network cards regularly disconnect for a few seconds, then reconnect. This seems odd, and it may be contributing to some network issues that people have been experiencing.

The model of the network card is Intel 82567LM-3. The driver has been updated to the latest version, which is from 2009. The desktops are running Windows 7 (some sp1).

The disconnect message in the System event log is this:
Source: e1kexpress
Event ID: 27
Task Category: None
General: Intel(R) 82567LM-3 Gigabit Network Connection -- Network link has been disconnected.

A few seconds later (can vary from 1 - 3 seconds), the reconnect message is posted:
Source: e1kexpress
Event ID: 35
Task Category: None
General: Intel(R) 82567LM-3 Gigabit Network Connection -- Network link has been established at 100Mbps full duplex.

Sometimes, it reconnects at 10Mbps, but usually at 100Mbps.

Haven't been able to find any pattern to the disconnects, but they do seem to happen only when a user is logged in (i.e., during usual working hours). Been thinking that this is some kind of sleep setting? Maybe after unlockiing the desktop after being away for awhile? This doesn't cause a problem for most users, but for some users (namely those in Marketing who are using Adobe InDesign that is accessing files on the file servers) this is causing data loss.

try different ports, or switches if it happens on many pc's


Not seeing any issues on the switches -- we did try using other physical desk-ports and other swtich ports.

Haven't verified this on every desktop, but it seems to happen on all of the Lenovo desktops that use that network card. The desktops are locatedThose disconnect / reconnect events don't happen on other devices in our environment (e.g., Lenovo laptops). So, it seems to be something with that specific network card.

Couple of things to try:
one fix may be to disable windows 'media sensing'


Did the network service stop? look in event log to see. maybe a required service is not starting or re-starting?

By default the settings are to disable split-tunneling.... Try disabling split tunneling and see if that works.


I found some other posts that discussed using an earlier version of the driver, so I went ahead and uninstalled the driver, then installed the "out of the box" driver that shipped with the operating system -- it was the only (Microsoft) -- version -- this is probably an Intel driver, just that it's got Microsoft listed as the provider, probably because it was part of the out-of-the-box drivers. The version that I had had was the version that gets installed when installing the latest driver from the Intel site -- 11.x.x.x.

This earlier driver seems to be working so far. I'll keep monitoring.
