I am using Fedora 8
I use both ndiswrapper from fedora repo and the tar and get the same error message.

Your using the wrong driver;

ndiswrapper (load_wrap_driver:118): couldn't load driver net8187b;

If the OS and ndiswrapper are 64-bit then the Windows XP device driver also needs to be 64-bit.

uname -a

You may need to blacklist the Linux driver for this device before ndiswapper can use the Windows device driver.

Indeed, and this is a matter that may be somewhat "invicible" until you try it. Blacklisting a driver (kernel module) means adding a blacklist modulename line to your modprobe's blacklist file. For more information, refer to modprobe configuration.
