Intel NIC I219LM random disconnects.

[TWrig6]

We've experienced random internet drops from machines that have the Intel I219-LM NIC. These have all been Lenovo machines (M920s and M920z).

We've attempted updating drivers, BIOS version, and reimaging machines multiple times.

WIN Version: 1803, 1809

Hardware ID: I219-LM

Driver Version: 12.17.8.9 (and older)

Initially this was isolated to one department who first brought up the issue last year around October. Recently it suddenly spread to other departments with no known fix.

As I mentioned, we updated driver and BIOS with what was suggested from Lenovo:

M920z Ethernet

M920z BIOS

https://pcsupport.lenovo.com/us/en/products/DESKTOPS-AND-ALL-IN-ONES/THINKCENTRE-M-SERIES-DESKTOPS/THINKCENTRE-M920Z/downloads/DS504738

But this has not resolved the issue. Any ideas as to how to resolve this issue?

(The information we got from the switch was that there was flapping.)

Hello TWrig6,

Thank you for posting in Intel Ethernet Communities. 

You may try our latest driver version 24.1, however this is a generic driver and not customized for their laptop system, that is why we cannot guarantee the compatibility of this driver to your system and NIC, it is still recommended to use driver from the laptop vendor or you may contact them for further assistance.

I will suggest this download and see if it resolves any of the issues and report back if it still continues.

Thanks!

Hello TWrig6,

I just want to check if you tried installing the driver version that we recommended and how is the system after that?

If you have questions, please let us know.

Hi Michael,

I installed the driver when it went out after using a USB NIC to connect online. Installing the driver fixed the issue for the time being. I'm not sure whether or not it was related, but about 30 min after installing it (without restarting) my computer froze and I had to do a hard reset. Everything came up normally afterward, but I'm unsure if the problem is resolved or temporarily fixed. I'll keep you up to date as more testing occurs.

Thank you!

Hello TWrig6,

That is a good development. Even though there are some issues after installing the drivers I hope the system will be fine after that. Just let us know how long would you like to observe the system?

If you have questions, please let us know.

Hi Michael,

I'll be monitoring this system for about a week, usually it'll come up and show issues at that point, I'll let you know if something happens so we can go from there.

Thanks!
