Today, when I turned on my PC (P2C point of sale) Operating system (Windows 10) showing RED mark on network icon. I started troubleshooting it but it is not showing in network connections even no option of Network adapter in device Manager. Although lights are blinking on Network adapter.
I checked in Bios, it was enabled, I re-installed Windows 10 but the problem is same, I updated Bios but still it is not showing in device Manager or in a network connection.
I also set power to the maximum performance but no love.
