Windows 7 Drops Network Connection when Suspended
I have a brand new, laptop at work, fresh install of Windows 7, all windows updates applied. The laptop is always on the docking station and always powered. My ethernet connection is hardwired and wireless is disabled. I have network access, Email,
Internet, etc.
PROBLEM: If I lock my computer and come back 15 min later, it drops the network connection. I enter my password, log on and abour 45 seconds later, my network connection resumes.
Co-workers have Vista and XP on their laptops and this problem does not happen to them.
My power options for the network card are turned off - it does not attempt to power down or reduce speed to the Network card when plugged in or on battery.
This problem happens when on batter or plugged in. seeing as everything eventually resumes and works, this is more of an annoyance than a permenant problem.
Any sugestions are appriciated.
thanks

Did you check the Windows setting - not the network card setting?
Right-click you battery-charging Icon, choose Power option and then change plan settings for the active profile.
In the new box, click advanced power settings and scroll through to the wireless settings and see if windows is taking control under it's power plan.
Actually - you didn't specify if you are on wireless or network, but either way - check out the advanced power plan settings and see if one of them are trumping your cards settings.

Hi Vince-at-work,
It seems that the computer is entering a sleep state while locked. The network connection delay is from resuming from the sleep state.
I would recommend that you change the advanced power settings in your power plan to extend the time to enter sleep when plugged in or disable sleep when plugged in.
Start\Control Panel\Hardware and Sound\Power Options\(change)Edit Plan Settings\Change advanced power settings
Then test for the behavior.

My ethernet connection is hardwired and wireless is disabled
I wouldn't think that wireless battery settings would have any effect on this but i've checked them anyway.
Active Profile - Advanced Power Settings - Wireless adapter settings - power saving mode
on battery: Max Performance
Plugged in: Max performance
__________
PCI Express - Link state power management -
On batter: Off
Plugged in: Off

Hi,
Please go to Device Manager, expand Network Adapters, right click your network adapter, click Properties, click Power Management, uncheck the box “Allow the
computer to turn off this device to save power”, click OK.
See if the issue persists.
Meanwhile, as a work around, you could
run the ipconfig /renew command every time that you wake the computer from sleep.
BTW, I would like to recommend you to visit:
You may experience connectivity issues or performance issues when you connect a mobile PC that is running
Windows Vista or Windows 7 to a wireless access point

Device Manager -> Network Adapters -> Properties -> Power Management:
Reduce link speed during battery operation <- NOT Checked
This is the only option under this box in relation to power saving options.
As for the article you sited, This is not a wireless connection
I have a laptop, in a docking station, plugged into the wall, hardwired with an ethernet cable. Wireless is disabled, we are not allowed to use wireless at work.
thanks for the attempt

Do you enable Screen Saver on your computer? If so, please read:
Computers that are running Windows 7 or Windows Server 2008 R2 stop responding at a black
screen if a screen saver is enabled
If the issue persists, type the following command to reset network:
Ipconfig /release
Netsh winsock reset
Ipconfig /renew

Was this ever figured out? I am having the exact same problem with a Dell E6500 series laptop with wireless disabled, on a docking station and hard wired into the network via the Intel 825xx network adapter. If I lock the computer by hitting ctrl + L and
go away for 10 minutes then come back and log on, the network is disconnected. I have DHCP disabled and a static IP address but Windows 7 still wants to find the network again and then I have to log back into exchange, communicator etc...and it's a annoying
problem to have.
I have changed all the power options that I think were relevant to this issue but none of them seem to have worked, I even got rid of some dell applications that looked like they may have had some influence on the problem but that did nothing.
Anyone know the solution?
Thanks!

Found the solution that worked for me on another site/thread.
Solution = change the network adapter settings to match the switch...don't let Windows 7 auto negotiate the speed, the problem went away. The answer was on the following site/thread: http://social.answers.microsoft.com/Forums/en-US/w7network/thread/f44f2e97-2a55-419f-a05d-92ad40098f18

I saw a setting while familiarizing myself with Windows 7 for Stopping or Suspending Network Connections when Screen Saver Activates. Sorry I can't remember where it is.
I do remember that it was the default setting and it was a check box that I saw after turning on the screen saver and pointing it to a folder with pictures but I can't find that tab again.
I believe that is the setting you need to find.
