I hope I'm posting this in the right section...

I'm using the Knoppix live CD. I've had no problems getting online with Knoppix, until I started trying to save my configuration to HD. (Because it's a pain to keep setting up fonts, printers, etc., over and over again.)

Right now, I'm using Knoppix v.5.0.1. I have a high-speed internet connection, and use a Motorola SB5120 SURFboard cable modem, connected with an ethernet cable at eth0. During boot-up, Knoppix detects the hardware...it's just that I can't get online with it now. I was able to get online easily before, and since shutting down Knoppix is supposed to wipe out everything done in that session...even if I made some mistake during that session, why would the same problem arise when starting Knoppix again?

I've had this same problem even after erasing the saved configuration file and creating a new one, in both this current version of Knoppix and Knoppix v.3.7 (the first version I used). At the moment, I can get online with the older version of Knoppix, but not the newer one.

I've searched forums, searched the internet, checked out Linux books at the library, and recently bought my first book about Knoppix...but I can't find anything that helps this specific problem I'm having.

Is there some way for me to manually check and adjust any ethernet settings so I can get on the Internet, when this problem arises? Please bear in mind I'm a relative newbie, with just a little experience in using the command line (though I'm willing and eager to learn more).

If anyone can help me with this, I'd truly appreciate it. Thanks in advance!

Post the results of ifconfig and lspci.

OK, cs.cracker, here's what I got:

Does this help?

====================

On edit: I got the problem solved by running "netconfig" in the root shell. Sometimes I have to run it twice, but at least it seems to solve the problem. I hope this will help anyone else who encounters this problem in the future.
