HI gooeywooey ,

Yes, I use ndiswrapper with broadcom card 4328. Your problem with ndiswrapper has been answered previously on this forum (search my posts). The short answer is "ssb" module interference. Make sure it does not load on boot. In 3.0, you can also use native broadcom-wl package (non-free) available in Slitaz repos.

Thanks

Your directions worked perfectly. Thanks.
