I have just upgraded to 13.04 (64bit) from 12.10. I had been using ndiswrapper-1.58cr1 for my wireless connection, but I can't get this to install in 13.04.
ndiswrapper -l shows :
david@Neewdesktop:~$ ndiswrapper -l
bcmn43xx64 : driver installed
device (0846:9020) present
but
david@Neewdesktop:~$ iwconfig
eth0 no wireless extensions.

lo no wireless extensions.
ndiswrapper version is
david@Neewdesktop:~$ ndiswrapper -v
utils version: '1.9', utils version needed by module: '1.9'
module details:
filename: /lib/modules/3.8.0-19-generic/updates/dkms/ndiswrapper.ko
version: 1.58
vermagic: 3.5.0-27-generic SMP mod_unload modversions

rfkill shows nothing is blocked.

Grateful for any suggestions
