Intel 3945 Wireless Code 12 Problem

Hey guys,

I have a weird problem with my Intel PRO 3945ABG wireless adapter on my dv6000t. Everytime after I've uninstalled a program and rebooted, my wireless goes dead. The wireless light indicator shows red (even if the switch is on the "On" position). And there is "!" mark next to the card in Device Manager, that says:

"This device cannot find enough free resources that it can use. (Code 12)

If you want to use this device, you will need to disable one of the other devices on this system."

So to get the wireless back to work again, I have to uninstall the driver, restart the computer, then install the driver, restart the computer... repeat the reinstallation up to 4, 5 times before the light turns green, and back to normal.

So, what is up with that? I already got the latest driver from Intel website, and this problem only happens when I uninstall programs and reboot the computer.... really weird.

Hope anyone can share some insights as to what on earth is going on, thanks in advance!

 

This has been a problem with many HP notebooks, more info below:

Read this thread On this forum.

Also, This one on HP's Business Support forum about the wireless problem.

See if your laptop is included in the "HP Limited Warranty Service Enhancement"

 

Thanks for the reply, but I have already checked, unfortunately my notebook product number is not listed in the Warranty Service Enhancement.

Unlike many others, my wireless adapter doesn't go dead after resuming from sleep or during normal use (it happened once or twice before when using old drivers, but not anymore). The weird thing is that it only goes dead after I uninstall a program and reboot my computer, even before rebooting it, it still works.

And because of the fact that I can get it back to work again by simply reinstalling the drivers couple of times, suggests that it's more of a software conflict problem than hardware. However, I've not updated the BIOS to the latest, since the update has nothing to do with the wireless card.

 

Sorry, have to bump...

 

Not all of the affected notebooks are listed and you do have a NVIDIA GPU. Still, I think the wireless problem is from NVIDIA chipsets, which you don't have, so you're probably right about it being a software problem... then again, NVIDIA GPUs put out a lot of heat and it may be cooking your wireless card. Flash in the latest BIOS update to see if its more aggressive cooling fan control helps.
