OK, let me try and walk you thru this.
For the D-Link, download this file:
ftp://ftp.linux-wlan.org/pub/linux-w...1-pre26.tar.gz
Make note of where you save it. Then, open up a terminal, and cd to that directory. Then type in 'gunzip linux-wlan-ng-0.2.1-pre26.tar.gz && tar xvf linux-wlan-ng-0.2.1-pre26.tar'. Hopefully this will go off without a hitch.
Then, once that is done, type 'cd linux-wlan*'. Once in that folder, type './configure', and if it runs without stopping without an error, after it finishes, type 'make && make install'.
Hopefully, that should install drivers for the D-Link.
Good luck.
