Hope you can help with this, I suspect this is a ill timed hardware failure but would appreciate your input.
I have a Dell Latitude D820 laptop running Win7 32bit OS.
BIOS Version: A07
The 'Intel(R)PRO/Wireless 3945ABG #2' card has recently, inexplicably stopped working.
Error: This device cannot find enough free resources that it can use. If you want to use this device, you will need to disable one of the other devices on this system. (Code 12)
This device is conflicting on PCI Bus 12.
Here's what I've tried so far...
Checked System Information for shared/conflicting IRQs.....none shown.
Disabled various devices and restarted to isolate conflict, no luck.
Checked all drivers are up to date, reseated wireless card and checked connections.
Booted laptop on a Ubuntu Live CD, ubuntu could not even find the device.
I have another D820 with the same OS & config so I swapped out the wireless card with a known working one, no change.
Swapped hard disks, the problem stayed with the Laptop hardware.
Reset the BIOS.
The only thing I haven't done is update the BIOS as I have a working D820 on A07.
The laptop did have previous issues with a faulty wireless/bluetooth switch, but this was resolved by repolacing the motherboard mid last year.
Thanks for your time.
