Ubuntu 8.04 Wireless

I googled out the wireless/ndiswrapper problem. The solution, quoting Ankur Srivastava's blog post, is as simple as this:

$ nano /etc/rc.local
then put
rmmod ssb
modprobe ndiswrapper
before exit 0...
...then
$ shutdown -r now

And your wireless is there.

Update: Apparently, these actions aren't needed if you're using kernel 2.6.24-17. After update from 8.04 original 2.6.24-16, wireless had not worked until I removed those lines from rc.local.
