Right, I am out of my comfort zone then!


It is imporatant to know what chipset it uses so you should do an lsusb
to see what actual dongle it is

https://elinux.org/RPi_USB_Wi-Fi_Adapters

should then be looked at to see what operating system versions support
that chipset and what firmware, if needs be, needs to be installed.

In particular:

"    D-Link
     ( DWA-131 (rev. B1) ) - Works now on Raspbian's kernel 3.6.11+
      or with DLink firmware: http://tsd.dlink.com.tw/

       DWL-G132 - In archlinux it is recognized - lsusb: 2001:3a03
         D-Link Corp. DWL-G132 (no firmware) [Atheros AR5523]
         - but no wlan0 device is created -
          perhaps it needs the firmware to be loaded"



It would seem that D-LINK dongles are not well supported at all.
If you want a quick fix buy a dongle from a raspberryPi vendor that is
known to 'just work' with whatever versions of OS you are running
