From: Hannes on 21 Oct 2009 03:04 Hi, We develop a USB network device driver based on MBN API for Wndows 7. When downloading something, the Windows 7 (7600) machine may still go to sleep in the middle of the download. If you make the same download through a fixed Ethernet cable or WiFi, the machine does not go to sleep until the download is complete. How can we control this behaviour from our NDIS MBN driver? Thanks, / Hannes.
From: Doron Holan [MSFT] on 21 Oct 2009 14:03 networking activity, no matter the phy, should not affect the machine's idle state. perhaps over ethernet or wifi it is just much faster than your MBN device so it completes before the idle timer fires d -- This posting is provided "AS IS" with no warranties, and confers no rights.

Our tests were executed with very large file transfers, and our customers see the same thing - the PC may go to sleep while downloading over our network device, but not over other connections. We set the sleep time to 1 minute to test this. So you are saying that Windows should always go to sleep, regardless of ongoing downloads etc? Do you think it would be a good idea for our driver to veto the system sleep event in order to delay the sleep until the download is complete (i.e. by measuring network activity in some way) ? Thanks, / Hannes.
