Ethernet/Cable Modem in Knoppix... Whiskey Tango Foxtrot?

Sorry, I seem to be asking the same question as a lot of people, but hours of surfing the forum haven't helped.
I'm running WinXP and Knoppix via bootable cd, and am having no luck getting my modem (A Terayon TJ 71x) to work.
This is what I'm doing right now, with "sudo netcardconfig":
ip = ipconfig "IP Address"
Default gateway = ipconfig "Default Gateway" (Imagine that!)
Nameserver = ipconfig DNS Servers (?)
Network Mask = ipconfig Subnet mask (?)
Broadcast address = I have no idea what this is.

This works a bit better than just entering the ip and leaving defaults (no network unreachable error within the netcardconfig thing) but it still can't connect to a remote ip.

If you have any ideas about a new direction to explore with this or think that any other information I can give you would be usefull, please do tell.

lspci sez:
Ethernet Controller: National Semiconductor Corporation DP83815 (MacPhyter)
Subsystem: Hewlett-Packard Company: Unknown device 0024
Flags: bus master, medium deusel, latency 90, IRQ 11
I/O ports at 8c00 [size=256]
Memory at d000a000 (32-bit non-prefetchable) [size=4k]
Expansion ROM at <unassigned> [disabled] [size=64k]
Capabilities [40] Power Management Version 2

It may or may not be helpful to note that the activity lights on the modem and the ethernet jack indicate swellness, despite their failure to operate.

Thanks in advance.

ED: My ISP uses dynamic IP assignment only.

Is your MOdem a Router/Modem, or just a plain Modem?

I'm having the same problems - see my post "Network help reqd, pls" and
earlier "Knoppix 3.4 and net conection via adsl router/modem and lan"

I believe it's just a modem, although I'm unclear about what constitutes a router. It only connects to one pc and the cable jack, so it doesn't seem that there would be much routing to do.

run netcardconfig as your doing and put in values for the DNS servers.

With out them your going no where. Your PC has no way to find for example, www.knoppix.net, with out DNS servers. Your ISP should have provided them for you on a set up sheet.

Network Mask aka Netmask should be: 255.255.255.0
Broadcast address will be: x.x.x.255 where x.x.x is MOST likely 192.168.0, but it depends on what you setup your network to use. It should match the first 3 of the IP address your putting in above.

Have you tried just letting Knoppix use DHCP? Does that not work to pull an IP and the needed info from the cable modem?

Most likely EXAMPLE setup:

IP Address: 192.168.0.2
Gateway: 192.168.0.1
Nameserver: x.x.x.x x.x.x.x (Thats a space to set 2 DNS servers)
Netmask: 255.255.255.0
Broadcast Address: 192.168.0.254


Now the cable modem could be using different IP ranges so check its manual to see what its defaults are.

If you have something like : 169.x.x.x for your IP address under XP in ipconfig /all then DONT USE IT. Thats an XP default.
