Download the latest network card driver.
Check netwkor driver softwares in Control Panel\All Control Panel Items\Programs and Features - if you see for example intel network driver or similar uninstall it.
Delete network card with driver in Compgmt.msc
Install the latest network card driver.

If the error still persist - maybe hardware issue!
