D-LINK DWL-G650+
The most annoying thing with this 802.11g WiFi card
is that although advertised with it the current drivers
still don't support WPA. Unfortunatelly to add that
is too big a task, but the second most annoying thing
is that the supplied utility only works with Administrator
priviledges and this is an issue I was able to change:
The supplied AIRPLUS.EXE file needs to be patched.
Make sure to do a backup! You need a hex editor for
that, any will do. The following table shows what bytes
at which address must be changed (Utility version 1.00).
To legally be on the safe side I will not provide a
ready-to-run download.

After those changes the application will 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 contain
a key like "dot11DesiredBSSID".
The US Robotics USR5410 card almost uses the same utility,
the same patches will probably also work there, though
I suspect you need slightly different locations. Also
I guess that the same utility is employed in the PCI
versions, like the D-Link DWL-G520+ or the USR5416. I'd
appreciate feedback on this.
