Here's the problem. You need to have ndiswrapper working in your Knoppix.
Ndiswrapper is available to the CD version of Knoppix via Synaptic IF
you already have an internet connection to bring it in. It is, as you
know, not already in the CD version of Synaptic.

One solution would be to connect via a direct ethernet connection to
bring in ndiswrapper and install it.

Another would be to buy or borrow a usb wifi to use temporarily, to
load it in to Synaptic. This, assuming such a wifi that Knoppix already
sets up automatically with a Linux driver.

Another would be to obtain the ndiswrapper file either via e-mail or
download or on some portable medium. I don't think it will matter
whether it's 1-57-1 or the latest version.
