My system has recently started coming out of sleep mode with the 82579V network adapter disconnected, however inconstantly.
A dialog box indicated the network adapter has disconnected due to an error.
Other application dialog boxes complain that they cannot connect to the network.
Intel Driver Version is 12.2.45.0 from the latest ProWin7_64_18 upgrade.
Under Properties only the [allow computer to turn off this device to save power] is selected.
To temporarily get the network reconnected I go into Device Manager and Disable and re-Enable the network adapter
and all is well until wakes from sleep mode.
Thanks, Rod...
