Vista - Intel 3945 Driver Issues

We have about 150 Toshiba M400 Tablets with Intel 3945 Wi-Fi cards in them.
We are a having a problem where the radio gets disabled and cannot be
enabled other than by a reboot. It seems to happen often out of Sleep /
Hibernate but at other times too. We had similar problems with the 3945
last year in XP until Intel fixed the driver. The newest driver available
from Intel is
http://downloadcenter.intel.com/Deta...&DwnldID=13001
which is 11.1.1.11. However I found on Dell this
http://support.us.dell.com/support/d...&fileid=220548
which is 11.1.1.22. Also it has the release notes:
Addresses 3945ABG radio disable seen in some 802.11a environments after
Standby or Hibernate

I was just wondering if anyone else had seen this issue. If so any fixes?
Has anyone tried the above driver from Dell? I have a school full of
teachers and students who are not going to be happy by random reboots needed
due the radio not working.

Thanks

Hello Brian,

Thank you for using newsgroup!

Based on my experience, there are some issues when we resume from
sleep/hibernate on Windows Vista. This issue occurs because of the power
saving features that are included in Windows Vista. The default power plan
that Windows Vista uses for a mobile PC is the Balanced power plan.

To work around this issue, use one of the following methods, as appropriate
for your situation.

Method 1: Connect the mobile PC to a power source
================
When you plug the mobile PC into a power source, Windows Vista switches the
wireless network adapter power setting in the default power plan from the
Medium Power Save setting to the Maximum Performance setting. This turns
off the 802.11 power save mode.
Method 2: Modify the default power saving power plan
================
Modify the default on-battery power setting for the wireless network
adapter. Configure the wireless network adapter to use the Maximum
Performance setting when Windows Vista is configured to use the Balanced
power plan or the Power saver power plan. To do this, follow these steps:
1. Click Start, type Power Options in the Start Search box, and then click
Power Options in the Programs list.

If you are prompted for an administrator password or confirmation, type
your password or click Continue.
2. Click Change plan settings under the power plan that is selected. For
example, if the Balanced option is selected, click Change plan settings
under Balanced.
3. Click Change advanced power settings.
4. In the Power Options dialog box, expand Wireless Adapter Settings, and
then expand Power Saving Mode.
5. In the list that appears next to On battery, click Maximum Performance,
and then click OK.

Method 3: Use the "High performance" power plan
================
If the computer is running on a power plan other than the High performance
power plan when you connect to a wireless network, manually change the
power plan to High performance. To do this, follow these steps:
1. Click Start, type Power Options in the Start Search box, and then click
Power Options in the Programs list.

If you are prompted for an administrator password or confirmation, type
your password or click Continue.

Note: You can also right-click the battery icon in the notification area to
access the Power Options command.
2. Click High performance.

For more detailed information, please refer to the following articles:

you connect a mobile PC that is running Windows Vista to a wireless access

Hope that helps!
