Ok did you configure you NIC card, when Knoppix comes up you access you main menu clicking the icon in your lower left side that has a Icon ilustrated with a Sproket with a "K" on top of it, that opens your main menu, ok. Then you look for Knoppix on this menu and select it the it open a sub-menu were you will select network/internet this will open another sub-menu were you will select network configuration card, when selected it will open a Console type subroutine in text and will start asking questions to you so it can configure you NIC card.

First it will ask if you use DHCP Server?
You will answer no.
Then it will ask you for your IP Number?
An show you 192.168.0.1 as an example there you will enter the IP number you normanlly use in that particular machine in Windows.
The it will ask you for your mask?
An show you 255.255.255.0 as an example this usually works so you can use that one as is.
Then it will ask for your publishing IP or something like it.
There it will show you as an example 192.168.0.255 this usually works so you can use that one as is.
The it will ask you for your gateway?
An show you 192.168.0.254 or something similar, if you are using a gateway because you connect thru a network you have to use the gateways IP this is normally 192.168.0.1 in personal o home networks, it is very important that you use the correct IP on this one so make sure you got it...
