My Killer LAN killed itself

Windows 10 has caused many networking problems with the most commonly used networking chips, such as any from Intel, and your Atheros E2200.

Features like Teaming on Intel networking chips has been broken for about a year now, and not fixed after five new releases of the Intel networking driver. I have personally experienced this on going problem.

This problem is a Windows 10 related problem, not something wrong with your board.

I see on your board's download page a newer Atheros driver, with a link to a guide for updating this driver for Windows 10. This guide seems to address the malfunction you have. Have you tried this procedure yet:
