Dear 星海观尘,
Thank you for contacting Intel.
Can you try the older driver version 20.6? This version contains igb-5.3.3.2.tar.gz. Because, I am suspecting that it could be incompatibility issue. In case you still the same error, we suggest to contact your system manufacturer to request for a validated driver.
You may download the driver here - Drivers & Software.
Hope this help resolve your network connection issue.
Sincerely,
Sandy
