G500 Driver_Power_State_Failure problem most likely related to Wireless Card

Question

I recently upgraded my Lenovo G500 laptop to 8.1.
After that, I've been constantly getting BSOD every time I modify some settings on my WIreless card (Broadcom 802.11n Network Adapter). For instance, changing my MAC under the"Locally Administered MAC Address" causes the Wireless configuration window to stop responding, then my wireless adapter becomes permanently disabled (I try to enable it and it says that it is enabling but the adapter remains faded out and locked in a disabled state) unless I restart or power down my laptop. If I restart, the laptop hangs for 3-5 minutes and then a BSOD comes up and suggests that I look online for DRIVER_POWER_STATE_FAILURE.
I have updated the adapter as well as most, if not all outdated drivers on my laptop with the 8.1 drivers offered on Lenovo's support pages (This includes power management, BIOS, LAN, Audio, etc.). Even attempting to voluntarily disable my wireless card causes the BSOD.
As long as I don't touch/modify such settings, I have wireless internet and all seems fine but once I do what I stated above, my laptop crashes with a BSOD. I have looked up and searched about such a BSOD but my laptop has zero problems when I put it to sleep or wake it up. My laptop functions practically flawless except for when changing/modifying settings on my wireless card.
For instance, on Whocrashed.exe:

This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

I ran SFC /scannow and it did detect corrupted files but that has been resolved using the Restorehealth command prompt. I have tried booting to safe mode, uninstalling the adapter and then updating straight to the most current 8.1 driver and that still causes the BSOD.
I'm almost certain that my wireless card probably is defective, or the laptop is defective. I'm still under warranty but I'm hoping to fix this issue before resorting to what I deem as last resorts of factory restoring the laptop or calling Lenovo support.
I am also providing minidumps, driver lists and a whole ton of useful information on my Skydrive:

Any suggestions or help on this matter would be greatly appreciated as I feel like I've exhausted all other methods.

"If I restart, the laptop hangs for 3-5 minutes and then a BSOD comes up and suggests that I look online for DRIVER_POWER_STATE_FAILURE."
I had the exact same problem on a Thinkpad Helix after upgrading to Windows 8.1, although I do not know if it was in anyway related to the wireless hardware as you described. However, I noted that in the Device Manager many wireless hardware components had been highlighted with an exclamation mark since the problem had occured (e.g. Bluetooth, Geolocation, Broadband). Here is how I fixed it:
1. I went to System Settings / Device Manager.
2. Disabled all devices that were highlighted with an exclamation mark. I noted that the Device Manager would not respond after disabling so I closed it and then chose to not wait (i.e. forced the Device Manager to close).
3. Repeated step (2.) until all devices highlighted with an exclamation mark were disabled.
4. Restarted the laptop (I don't know if I had to force the shut down via power off at that time, but it may be necessary or you wait for the BSOD).
5. Repeated step (1.) and uninstalled all the drivers of the devices disabled in steps (2.) to (3.), enabling the option to remove the driver from the system, where possible.
6. Restarted the system. This time the shutdown should only take a few seconds.
So far, everything works fine again and I cannot identify any limitations through the disabling and uninstalling of devices (esp. wireless devices do work flawlessly).
Hope this works for some of you guys out there as well. Let me know.
Good luck!
