That Microsoft was using plus supplied the wrong driver. Be sure to disable driver updates in W10 and go get the one specific to your board. Be sure to boot Safe Mode and remove the non-working adapter and driver.
Finally I take it that other laptops, PCs, XBox and such are fine on this cable. I've lost count of cable failures.
The clue it's the driver and Microsoft's choice of driver is the 2 weeks till it stopped working.
All online solutions I have tried do not work. All solutions here I have tried and do not work. Went to brothers with different ISP and router and it still did not work. I've replaced my motherboard (ASUS H170 Pro Gaming) with a brand new one and nothing. The only thing that HAS worked was totally wiping my computer and reinstalling windows 10. After 2 weeks, it stopped working again.
1) When I came home that day, computer was off which means there was either power outage or update and my comp turned off as it is usually sleep mode.
I have a laptop running windows 10 and the ethernet cable connections works fine with it. Also works with xbox.
I called a computer shop and told them everything I've done and they told me (honestly) that I'd waste my money going there as I've tried everything they would have.
I'm pretty tech savvy but hoping I'm missing something dumb.
