Hi,

I've been running 9.1 Pro on my main PC for nearly a year now and have
learned a lot from reading this group. Thought I'd post about my
experiences with getting this wireless card working.

Got an old laptop (Gateway Solo 9300) for free from work a while ago and
put 9.1 Pro onto it with no problems - a bit slow but quite usable. It
came with no LAN / WLAN support so I bought a Netgear FA511 cardbus
ethernet card for it, Suse recognised this out of the box - happy days.

Wanted to set it up on wireless though, so I recently got a D-Link
wireless bundle (DI-624+ ap/router and DWL-G650+ cardbus card) from
expansys.ie - pretty good deal at 80 euro for the pair inc. postage

I thought the card was supported by Linux but it wasn't! The D-Link
website lists cards which have Linux drivers at
http://support.dlink.com/faq/view.asp?prod_id=357&question=General%20Wireless

but it only lists products on sale in the US, and the G650+ isn't on
sale in the US. The 650+ and G650 are shown as Linux compatible, I
thought the G650+ was the same as the 650+ but it isn't! The G650+ has
the ACX111 chipset, I thought it had the ACX100, drivers for ACX100 are
available via YOU.
(Why can't DLink quote a unique Product ID for each model? The product
names are confusingly similar.)

I discovered that the UK and German D-Link sites don't seem to give any
information at all on Linux, I'd already bought the card by now, so time
to try ndiswrapper...

Took about ten hours (including a lot of googling) to get it going but
it now works fine. This is how I eventually got it working, after a few
false starts (I'm using the latest kernel from YOU, 2.6.5-7.155.29):

-Uninstalled the SuSE ndiswrapper and built version 1.2 from source.

-Uninstalled Suse wireless-tools and built & installed version 27.

-Installed ndiswrapper using the Windows XP driver from Dlink, following
the ndiswrapper instructions

-modprobe ndiswrapper now worked fine (I always failed at this point
using the ndiswrapper version that came with 9.1)

-ndiswrapper -m

-I had the link LED lighting at this point, and iwconfig showed signal
strength etc.

-tried ifup wlan0 - got error messages that wireless-tools wasn't
installed! Seemed to be a path problem, rather than fiddle with that I
tried just moving the wireless-tools files (iwconfig, iwevent, iwgetid,
iwlist, iwpriv, iwspy) into /usr/sbin.

-Still no joy so in desperation I tried reinstalling the SuSE
wireless-tools from my CDs - this worked

-ifup wlan0 brought up the card and now I could see the access point and
access the net :)

-When I rebooted, the card came up automatically, DHCP works fine etc.

Next step: configuring encryption, which I should be able to do with
Yast. Reading up first about WLAN security issues in general (never used
one before), in the meantime I'm keeping the WLAN turned off!

General info, not very specific (at least not for the chipset I'm
using), but well worth reading before you do anything else.

Not all that helpful,as I wasn't able to remove Suse's acx100 driver by
following the instructions, but that doesn't seem to be causing problems.

Specific instructions for Suse9.2 Pro - not applicable to me :)

There is lots of great stuff on this site or linked to from here, in
particular the latest wireless-tools versions at the URL below:

Hope this is helpful to someone.
