driver for dwa-125 in Lucid Puppy
 

Hi,
I would like to get some help with wireless connection in my Lucid Puppy 5.2
My old desktop works with a D-Link wireless 150 USB adapter - DWA-125. Lucid Puppy 5.2 does not have an inbuilt driver for it. Searching in the internet, a found that the driver should be the rt 3572sta.pet. I downloaded it in an pendrive (as my desktop is not connecting to the internet by fault of the D-Link USB adapter)But I don't know how to put that driver in the kernel of the Lucid Puppy, which runs in a CDRom.
Could anyone help me with detail, as I am a newby?
Thanks
Josef
