And:

# lsmod ndis

If it isn't there, you need to 

# sudo modprobe ndiswrapper

That sounds like complete crap to me.  I can't imagine any way that NM cares
what the specific modules are.  In fact, my acx chipset using ndiswrapper
works fine under NM.  As far as NM is concerned, it's just an interface.

wifi-radar may well work _better_ but it's more useful to really know the
problem first, than to start uninstalling software based on really suspect
sources.

Then why are you telling people to uninstall Network Manager?
