I have an Atheros ar8151 ethernet controller built into a motherboard. It works fine at switch on then after an indeterminate period of time simply stops. Windows 7 claims it's still working. IF I shut down and restart it usually works again although sometimes it needs a full power off.

Anyone else dealt with this issue?

Built in ones seem less reliable I use cards

Are you sure its that and not your router for example?

I had a similar issue with the wifi in a laptop when upgrading to Windows 10 recently. The laptop was about 5 years old, had to reinstalled 7 on it because there was no fix for the driver issue.

Looked around for any driver related issues with that product?

The cable runs straight into a 4 port Netgear WNCE4004 wi-fi adapter. I have 2 computers, side by side, connected to the same adapter. One keeps running without issue, second falls off the internets? It doesn't come back up either until I shut down.

I am getting occasional disconnects but internet on both computers goes down at the same time.

Adrock, there are a huge number of older devices not supported by Win 10 and the makers aren't going to update their drivers. The Atheros ar8151 seems to have quite a few problems.

It wasn't a Dell by any chance? I had the same issue, couldn't find anything online officially supported so downgraded to the exact same driver W7 was using and that then worked fine ever since

Maybe harder to get proper drivers for onboard cards when upgrading ?

you could check the power saving settings ?  could be powering it down because OS thinks it's inactive ?

have heart of that before with other stuff

After much searching I found a newer version of the official driver, it's supposed to be more stable than the old one.

But why the old one remained stable for so long and just started falling over recently? May be that changes to Windows made it less stable, or it got slightly corrupted.

Obviously the dark side is rising... Where the hell is Luke Skywalker and the Jedi when you need them? :/
