Ethernet help
It might be in the incorrect category, but you're having trouble connecting an Ethernet cable to your gaming PC. Your motherboard is the MSI B450i Gaming Plus AC. The cable is brand new and functions on your laptop, but it doesn't work on your desktop. Ethernet isn't listed in any settings and appears to be missing. You've tried reinstalling drivers and other fixes. Note: The error message says the Realtek network controller wasn't found if deep sleep was active.
I've been relying on the built-in Wi-Fi of the motherboard ever since I assembled my PC, roughly a month ago.
I notice these issues are clearly recorded, which might offer useful guidance. However, since it's MSI, the situation could be different.
Ensure the Ethernet card is activated in BIOS and verify drivers are available. The Realtek® 8111H chip should come with built-in Windows drivers, though MSI provides additional options on the driver page. You can download it directly here: http://download.msi.com/dvr_exe/realtek_pcielan_w10.zip (for Windows 10 64-bit).
I purchased an external adapter for the ethernet port, and it functions well. Although I only achieve half the speed of my laptop via cable, it's manageable. A 100mb download still performs adequately.
