    Broadcom 802.11n Network Adapter errors Code 12, 10, 45

    Hi everybody, I have several issues with my Broadcom 802.11n Network Adapter.

    My system is a Windows 8.1 x64 Enterprise with Boot Camp 5.1 running on a 2011 Macbook Pro.

    Since a couple of weeks ago, this adapter has been very unstable. Usually I observe this pattern:

    1. The device works and I'm connected to some wireless network.
    2. After a while the network goes into "No internet access" (with the yellow triangle in the taskbar) out of the blue.
    3. I try to disconnect and reconnect from the network I'm connected, or I try to disable and re-enable the wireless adapter (the result is identical).
    4. The device disappears from the Device Manager list, in the sense that is not there anymore. If prior to it disappearing I left a device manager window open, I see the error: "This device cannot start. (Code 10). This device does not exist." or "Currently, this hardware device is not connected to the computer. (Code 45)". It's like I physically unplugged it from the system, indeed I still can see it in "Hidden Devices".
    5. Alternatively, the device is still in the Device Manager list with the error: "This device cannot find enough free resources that it can use. (Code 12)". Sometimes, when I click "scan for hardware changes" the device disappears.
    6. I reboot.
    7. Now, sometimes I even have to reboot 2-3 times*, but after that I see the device back again in the device manager list.
    8. The device is either (1) shown as "Unknown Device", (2) or as a generic "Network Controller", (3) Broadcom Network adapter with the yellow triangle. In all these 3 cases, I have to re-install the drivers. I reinstall the drivers, reboot, and things go back to step 1.

    Things I tried to do (with no success)

    1. Clean Uninstall/Reinstall the device drivers (even from the state where the adapter is working)
    2. Trying both Boot Camp drivers, and drivers from the manual installation list that you see via Browse my computer for driver software > Let me pick from a list of device drivers in my computer.
    3. Clean Uninstall/Reinstall of the whole Boot Camp drivers suite
    4. Disabling/re-enabling the Device several times without reinstalling

    Some quick facts:

    • The device now and then pops in the device manager with a progressive number, something like: "Broadcom 802.11n Network Adapter #2", "Broadcom 802.11n Network Adapter #3" and so on. Indeed, if I show even the hidden devices, I see the old ones as disconnected, and the current one that is working as #3 or #2. Same thing as for the wireless adapter I see in Network and Sharing Center > Change Adapter Settings. Sometimes it is "Wi-Fi 2" instead of the regular "Wi-Fi". There might be a conflict somewhere I think.
    • After reinstalling the device, it has no memory anymore of the visited networks, in the sense that I always have to re-enter the WiFi password. I guess this is expected.
    • I remember prior to this mess I was deleting some unused networks via regedit following this procedure (method three). I suspect something might have gone horribly wrong there.


    * This thing really freaks me out. I was born in the dogma that if I chain-reboot a computer without performing any operations, the state should always be the same. Guess it's not the case.
