Finally someone tackling the exact same ploblem! I thought I was the
only one with that card...

I have tried, for a very long time, to get this to work with
linux-wlan-ng and ndiswrapper,  I didn't get it to work yet.  The
furthest I got was with linux-wlan-ng and an open router, and this
wasn't very reliable.  Unfortunately, I need this card to work with
an encrypted link.

My latest attempt was with ndiswrapper, and was told that it won't
work.  At the bottom is the reply I got when I asked for help on the
ndiswrapper list.  I have not been able to get the firmware, the
location probably has a problem with privoxy (that I run) or the
way my connection is set up.  I'll have to try the firmware that
comes with linux-wlan-ng (there are 3 of them and I haven't looked
at that in detail yet).  It would help to know which firmware actually
works.  The other thing is that I want to do this with a 2.4 kernel.
I'd rather not go through the massive upgrades to Debian stable that
using a 2.6 kernel entails.

Ok, now that someone else is interested in getting this to work,
we can hopefully pull it off.  Let's try this, compare notes,
details, etc... possibly off-list, and see if we can get this card
to work with a 2.4 kernel and an encrypted link.

HostAP will work. Use the latest 0.2.x version. See:

This particular revision of the DWL-650 doesn't have the full firmware 
on-board; it is loaded by the operating system. I think that the USB driver 
has the Prism firmware in it, this is why it is in the Windows driver 

Anyway, this card will not work with ndiswrapper. Ndiswrapper only supports PC 
cards that use a 32-bit (CardBus) interface. This card is a 16-bit PCMCIA 

Use HostAP. It is a well-written driver and works very well. In fact, this 
message was sent over a DWL-650 rev. P driven by HostAP ;-).


P.S. BTW, I know that D-Link's (boneheaded) support site says to use 
linux-wlan-ng with this card. While this project has support for Prism3 SSF 
cards, HostAP's is better by far, and HostAP supports the wireless extensions 
API. There's only one thing worse than a vendor not supporting Linux: that's 
supporting it and getting it wrong. :-/
