Hi, again DirkS

It never occurred to me that your problem was not having internet.
How is it we are having this dialog? And, where did you get 6.4.3?
Clearly, we need to know more about your set up: Live or HD,
CD iso or DVD, etc.

I only use the CD versions of Knoppix, but I know the DVD
versions have much more software on them to choose from.

I favor Knoppix as a LiveUSB with persistence because I never
liked the hassle of dual-booting. I'm blessed with broadband internet.
Also Knoppix is the most friendly of all distros in regard to the
Broadcom wifi that's in my laptop. I also favor the LiveCD iso
over the DVD since it allows very compact USBs to be made from it.

LiveUSBs made from a Knoppix LiveCD iso have a built-in option that
gives you a chance, albeit brief, at every boot to establish persistent
store, until such time that you do so.
