Hi guys
Have encountered a strange issue with 2 PC's. Both have identical installs and only run 1 application.
After an idle period, the NIC disconnects and requires a disable/enable to re-establish comms. The on-board network port remains active and functional. Issue is with the secondary card.
Are there any power management or card specific settings to stop this from happening?

OS is Win 7 64Bit

I have had a scrounge around the settings and cannot see anything that would be stopping the card, initially thought it was power management.

Thoughts welcome

Have you checked the Power Management tab on the Properties of the device in Device Manager? There may be something there.

Also look for 'reduce link speed' in the network cards power management & turn that off.
You may even have to upgrade the drivers to disable that.

Just incase this lurks someone else, there was a PCI power management setting in the BIOS that was causing issue coupled with the power management in Windows.
Changed power to performance also
