Ethernet connections won't recovery after cable reconnected

[HuHao]

Good day!

I'm experiencing an issue with the Intel(R) I210 Gigabit Network Connection. If I start my PC without a network cable connected and then connect the cable after Windows 10 boots, the Ethernet connection doesn't automatically reconnect. A globe icon is displayed in the lower-right corner of Windows' status bar, indicating that no internet connection is available.

This doesn't happen every time, but it has a high probability of occurring (over 80%). When the automatic reconnection occurs, the Event Viewer outputs a line like this:
"Intel(R) Ethernet Connection (17) I219-LM: Network link has been established at 1Gbps full duplex."
After this, the internet connection is re-established.

However, when the issue occurs, this line is not output, and no network connection is available. Strangely, when I disable the Ethernet adapter in the Device Manager and then re-enable it, the network connection is re-established.

Does anyone know the reason for this? Any suggestions are appreciated!

Hello Vikas

Thank you for your reply and kindly help.

I'm sorry I forgot to provide the detail information.

The issue happens on a IOT device with Windows 10 LTS installed, the Windows version is:

Windows 10 Enterprise LTSC

Version 1809

OS Built: 17763.107

The NIC is I210 Gigabit Network Adaptor with the following driver installed:

I also tried to update the driver to the latest version as below, but the issue still happens:

About the Windows version, I also tried to update to Windows 10 IOT 21 LTSC  with a clean installation, but the issue still happen. I happened to have other IOT devices of same model with the same NIC installed on them, the issue happens on all devices.

Thank you again for you help and look forward for your reply.

Best regards,

Hello Huhao,

Greetings!

Thank you for the information shared, from the model of the ethernet adapter (Intel(R) Ethernet Connection (17) I219-LM), we believe this is a LOM (LAN on Motherboard).

Hence, have you contacted your system manufacturer to get yoru BIOS and Firmware updated, they might have latest relases that would address this issue. Besides that, you can try the steps below and check for the outcome

1) Network Connections > Clicked on Ethernet > Properties > Configure ... > Advanced

• Speed and Duplex > Tried 1.0 Gbps Full Duplex AND 2.5 Full Duplex

• Disabled IPv4 Checksum Offload

• Disabled Large Send Offload V2 (IPv4)

• Disabled Large Send Offload V2 (IPv6)

• Disabled TCP Checksum Offload (IPv4)

• Disabled TCP Checksum Offload (IPv6)

• Disabled UDP Checksum Offload (IPv4)

• Disabled UDP Checksum Offload (IPv6)

2) Network Connections > Clicked on Ethernet > Properties > Internet Protocol Version 4 Properties > Advanced... > WINS > Enable NetBIOS over TCP/IP

3) If it still does not work, contact the manufacturer for possible RMA.

Please also be informed that we don't support OEM nor LOMs. Hence, we would recommend getting in touch with your system manufacturer for further assistance. You can go through the following link for more information: https://www.intel.com/content/www/us/en/support/articles/000005612/ethernet-products/gigabit-ethernet-adapters-up-to-2-5gbe.html

Many thank to everyone!

Finally we found that this issue only occurs on one of our hubs which provide a class C IP-address. 

The strange thing is that, if we connect another hub on it, and connect our devices to another hub, the issue gone.

Also, our other devices seems don't have problem with this hub.

Any way we decide to resolve it by using other hubs.

Thank you all for your kindly help and will you a nice day.
