I don't understand your complaint relative to Knoppix 6.7.1.

You can locate most any software that's available by choosing your repositories
and reloading Synaptic.
The availability of non-free firmware is not controlled by any Linux developer.

Of all the Linuxes, Knoppix has one of the best reputations in regard to the distribution
itself working with the widest assortment of computer hardware.

If you have a specific configuration problem, there are people in this forum
which can probably help, but you'll have to be more specific.
