ok i thought i would update the post in case this problem is not unique to me.
i eventually got the light to come on the network card by following this tutorial.
http://wiki.waningsun.net/index.php?...26_Linux_HOWTO
This effectively removes the bcm43xx driver which is known to play havoc with ndiswrapper.
i installed the latest ndiswrapper from the site (currently 1.43)
adding the ndiswrapper to /etc/modules meant that the driver starts at boot. a quick check on System > device manager confirmed this.
yippee.
im still not there as my wireless still doesnt find any networks.
using sudo iwlist wlan0 scan
however the network manager now recognised the presence of my card and i can scan using the gui rather than the command line. (thats progress)
any body with any clues as to why my set up doesnt find the network please shout out.
im using
ndiswrapper 1.43
belkin/broadcom card using bcmwl5.inf windows driver
ubuntu ultimate 1.3
with a wireless-G network
and a 64bit hex wep key
all the hardware works fine as booting the same machine into the dreaded XP works flawlessly as expected.
