D-LINK DWL-G650+
(also good for DWL-G520+ PCI card)
Finally D-Link has released a WPA compatible driver
for this card. However, once again the supplied utility
does not work without Administrator privileges, therefore
a new patch was in order. The patch for the previous
utility can still be found here.
With the addition of WPA and the Funk WPA supplicant
the code of the new utility is much more complex than
the code of the previous one. So, considering my limited
amount of time, this time I didn't do a full analysis
of the code but just some educated guesses on what needs
to be done. So yes, this is experimental, but so far
it works without a glitch here.
And yes, you could also just start the original utility
with the "Run as..." feature, but this has
some drawbacks. For example, whereas on my laptop the
original utility run as an Administrator needs 32 seconds
to reestablish the connection after resuming from suspend
mode the patched utility running with user privileges
merely needs 6. Quite a difference, I think.
The patch
As usual you will need a hex editor do to this. In
order to make this work I had to patch all 3 files,
the DWLGTI.EXE, ExtWLANConfig.DLL and
odSupp_M.dll. Make backups before applying the
patch!

After those changes the application will probably already
run as a normal user. You can't however do any changes
to the configuration. To do this you need to give the
user write access to a certain registry folder (using
REGEDT32).
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Class/{4D36E972-E325-11CE-BFC1-08002BE10318/xxxx}
Where xxxx is a number like 0001 and depends on your
specific installation. The correct branch should have
the text D-Link AirPlus G+ DWL-G650+ Wireless
Cardbus Adapter in the DriverDesc
key.
