If you're having issues with a network adapter, sometimes the first step is to uninstall it from Windows, restart, and let Windows reinstall it. This often happens after Windows updates or after installing a bad driver.
Type Win + X and select "Device Manager." Expand "Network Adapters." Right-click the adapter you need and select "Uninstall device." Restart and let Windows reinstall the device to see if that fixes any issues you're having.
