I've been using ndiswrapper with a USB wireless dongle for a couple
years under RH Fedora -- as the kernels are updated I've had to
get newer versions of ndiswrapper.   I have a couple different dongles,
and the drivers appear to differ in the stack requirement.  The one I
use works reliably with RH 4k stacks.

I also tried ndiswrapper n a recent Knoppix, but couldn't get
it to work at all.

I'm using an SMC router, and and see similar behaviour -- generally
the initial connection is good, sometimes last days, but once the
connection is lost it can be tricky to get it back.   Careful adjustment
of the antenna position on the router and the location of the dongle
seems important, but the PC is 2 floors above the router.  The most
reliable way to get the connection back seems to be "rmmod
ndsiwrapper; modprobe ndiswrapper" then run iwlist scan a few times
until the right AP appears on the list.

I don't recall any parameters other than the name of the interface.  What
does "modinfo ndiswrapper" offer?
