A short, practical checklist that fills the gaps from the replies above.

As implied, eth0 is the wired (Ethernet) interface; wireless shows up as wlan0 on older systems or as predictable names like wlp2s0 on newer installs. Knoppix asking for an IP/subnet is just asking whether to use DHCP or a static address (same concepts as Windows — DHCP is the normal choice). For general diagnostics and the basic workflow (identify card → check driver/firmware → check hard/soft block → connect) see the Ubuntu troubleshooting notes and the interface-naming guidance.
Ubuntu Wireless troubleshooting • Network interface names (Debian)

Quick commands to run from a terminal (live image or installed system): bring up which hardware, driver, and block state; then try a software connect:

sudo lspci -nnk | grep -iA3 net
lsusb
ip link show
rfkill list
dmesg | egrep -i 'firmware|wlan|wifi|b43|brcm|iwl'
nmcli device wifi list
nmcli device wifi connect "SSID" password "PASSWORD"

The Ubuntu diagnostic HOWTO above bundles the same checks and explains common error outputs; the nmcli reference documents the command-line connect flow if NetworkManager is present.

Knoppix notes: if eth0 is up but it asks for IP/subnet, choose DHCP unless a static address is required by the network. To force a DHCP lease from a shell use sudo dhclient eth0 (or the wireless interface name). Static configuration requires IP, netmask, gateway and DNS entries — same fields as in Windows; Ubuntu’s networking guide shows examples.

About ’s NDISWrapper tip: NDISWrapper is a legacy fallback that lets some Windows drivers run on Linux, but it’s seldom needed today and can be fragile. First try to identify the exact chipset and use the kernel/open-source driver or the distro’s “Additional Drivers” packages (Broadcom chips, for example, have specific instructions). If no native driver exists, follow the NDISwrapper docs carefully.

eth0 won't be your wireless interface, but the ethernet interface.

if that is the only interface you are getting, you need to install your dirver and that is different depending on what you device is.

About knoppix I can not help. Never used it. About Ubuntu -> Please give me the version you are using and the type of wireless card (make & model). Installation differs for different versions.
Once we have this info I should be able to help.

Update
Sorry - had to attend to customer. Ubuntu supports NDISWrapper which allows using a Windows wireless driver under Ubuntu.
For help go to System -> Help and Support -> Internet -> Wireless Networking -> Using Windows Wireless Drivers.

That should get you going in most instances.
Hope that helps.
