NDIS6 Network Driver breaking Local Area Connection on Sleep Resume

Reported by: GabeF Owned by:
Component: network/hostif Version: VirtualBox 5.0.6

Description

There appears to be a problem with the NDIS6 driver handling power state changes.

Since updating to VirtualBox 5.0.x, my Local Area Connection reports "Network cable unplugged" after waking up from sleep.

This issues does NOT occur if i uncheck the VirtualBox NDIS6 Bridged Network Driver on the connection.

Workaround 1: Disable the Virutalbox VirtualBox NDIS6 Bridged Network Driver on the connection

Workaround 2: disable and re-enable the interface every resume. Workaround 3: Configure the Network Adapter Hardware power management to disable "Allow this computer to turn off this device to save power."

Disabling power management on the interface not only prevents the issue from occuring, but also returns it to service after a sleep/resume cycle without having to disable and re-enable the interace.

I think this issues could be related to some other host<->guest networking problems commonly reported which I also run into.

My Hardware: Dell Precision M4800. Intel Ethernet Connection I217-LM. Driver version 12.12.50.7205. Connected via docking station.

I'm trying to find a way to get into debugging the driver, but could use some guidance.

Forgot to add: Windows 7 host. VirtualBox 4.x uninstalled before install.

Update: This apparently isn't NDIS6 driver specific! Please rename the bug.

I can reproduce "Network Cable Unplugged" when resuming from sleep using VBox 4.3.30.

I confirmed 4.3.28 and 4.3.26 do not have this problem.

Just to be explicit - This "cable unplugged on resume" also exists with installs of 5.0.4 and 5.0.6.

I hope the following facts are most useful

  1. introduced 4.3.30. Continues in 5.0.6
  2. Workaround available by disabling power management on the network adapter.

Thanks for the useful app!
