I've followed every direction I could find on related Google searches on the first couple of pages. No solutions I've found have helped. For example, this is one of the sites with the most easy to understand solutions but none of them worked: https://www.windowscentral.com/how-regain-internet-access-after-installing-update-windows-10

I have no idea why this could be happening. I have had this computer since January, never had a hiccup. In Device Manager, the device shows up as working properly.

The only fishy thing is that when I disable the Ethernet Controller in Network Connections, then enable it again, it does not enable. When I close Network Connections and re-open it, its no longer there. It still shows that it is working properly in Device Manager, however, and when I restart my computer it is enabled and displayed as usual in Network Connections. Its just that it doesnt detect that there is any connection.

I really hope there is a solution someone can point me toward that I haven't tried yet or that is actually guaranteed to work. Thanks.

Ps. The Ethernet Controller is a Qualcomm Atheros AR8171/8175 PCI-E Gigabit Ethernet Controller (NDIS 6.30)

Hi Math Geek,
I don't have the option to roll back the update. Not sure why. Another frustrating road block.

Edit: as i understand it, the "go back to a previous build" feature is only displayed when a major update has occurred within the past 31 days. Otherwise you can uninstall the latest updates elsewhere, which I have already tried with no success.

Any other ideas?

if you have an older iso of win 10, you can install that again over the update.

otherwise, you're gonna have to wait it out without ethernet working until MS puts out an update. not the best option but likely the only one if you can't roll-back the update.

other thing that sometimes works is to install an older driver for the ethernet from the mobo download page. it's possible a new driver was installed from MS that does not work. installing an older one from another source may get it working again.

I couldnt find any other versions of the driver from the driver's website. I'm not sure where else I could look.

Would it be an option to do a "System Reset"? - the one where you can keep your files but lose your programs?
That would be kind of my last resort but if it had a high probability of success it would maybe be the best bet?
Waiting without my desktop simply is not an option for me. I don't have a copy of my Windows 10 either.

I'm sorry-- I'm not really sure what that is. How can I check that and enable it again?

Thank you for your help!
