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?

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

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.

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

After much searching I found a newer version of the official driver, it's supposed to be more stable than the old one.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