"The article How To Share The Internet Connection Between Mac and PC from makeuseof.com notes ""40-bit WEP encryption didn’t work when trying to share the internet connection between Macs and PC"" and suggests:

Even when entering a hexadecimal key on the Windows client then still be sure to use a 5 or 13 character password in your Mac's sharing settings. If you want to enter a hexadecimal key in your Mac's Internet Sharing, then maybe you can do so by prefixing the value with ""0x"" or ""$"" and use all uppercase, as per Entering a WEP hex key for preferred AirPort network on macosxhints.com (though that is not about Internet Sharing)."
