    Hello Everyone

    I have 2 USB wireless adapters, one is Alfa AWUS036H with Realtek chipset RTL8187L and the other is AWUS036NHR Realtek RTL8188RU Both adaptors are giving me hard time on a windows 7 64 bit installation whenever I try to enable the Microsoft Virtual Wi-Fi Miniport Adaptor on any of them. Any attempts to update or fiddle with the drivers on the Virtual adapter will immediately BSOD the system. I have installed and uninstalled the drivers and ccleaned after reboot at least 20 times but to no use. I have also tried several versions of drivers including the ones from Alfa (manufacturer) and the newest ones from Realtek.

    Both adapters work fine in another windows 7 64 bit computer, which leads me to believe that they are conflicting with other drivers or devices installed in my computer and I have no idea how to find out. Unfortunately formatting the computer is not an option right now.

    Any help will be greatly appreciated

    Trying to figure out what the conflict is will require more work than starting from scratch and doing things one by one. What you need to do is get a memory dump. You will have to find out the interrupt number assigned to each device in your system. The BIOS will assign from 1-13 and Windows will assigned from 14 and on. You need to consider the drivers for the devices that share the same interrupt number as your wireless card. This is a good starting point for figuring out the conflict.

    A quick Google search should give you the necessary free tools to examine memory dumps.

    Thanks metril for pointing out the way, someone analyzed the dump for me and found out that amppal.sys, Intel® Centrino® Bluetooth 3.0 + High Speed Virtual Adapter is the reason why i was getting the BSODs, so I removed the drivers and everything is working just fine now :).
