I also have the same problem. My broadcomm 43xx wireless adapter worked in dapper with ndiswrapper, but modprobe ndiswrapper returns an "invalid argument" just like this one.
After doing some research, I found the below link, and I'm hoping that the final release will include some means of addressing this situation: http://ndiswrapper.sourceforge.net/mediawiki/index.php/FAQ#When_I_run_.27modprobe_ndiswrapper.27.2C_I_get_.27Invalid_module_format.27_or_.27Invalid_argument.27_error_or_something_similar._What_do_I_do.3F -- fails to load module after edgy upgrade https://launchpad.net/bugs/66016 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
