Knoppix can't reach wireless network

A friend gave me a CD of Knoppix 3.9 recently. This is the Linux distro that operates entirely from the CD. It boots my PC, etc., but I can't reach the Internet. This is probably because I'm on a wireless setup. I can reach the Net if I plug into the router by cable.

My wireless card is a Linksys WMP54G and the router is a Linksys WRT55AG.

I went to some of the Knoppix forums which recommended some scripting, but since the OS isn't installed on the hard drive, but remains on the CD, you can't write any changes.

Is anyone here familiar with this problem?

Here is a sample of the code recommended for Linksys wireless setup being run on Knoppix:

As root, edit /etc/resolv.conf to include the IP address of router as nameserver:

# Insert nameservers here
# nameserver


Edite /etc/network/interfaces to configure a static IP for the wireless network adapter:

#/etc/network/interfaces -- configuration file for ifup(Cool, ifdown(Cool

# The loopback interface
# automatically added when upgrading
auto lo
iface lo inet loopback
iface ath0 inet static
wireless_essid youressidname
wireless_mode managed
wireless_key xxxxxxxxxx
wireless_channel 9
wireless_txpower 50mW

Many thanks in advance,

I had a similar problem on my laptop when first installing SuSE (I now use Ubuntu - much more friendly distro Smiling ). As it turns out - and this is sad - I hadn't pressed the wireless power button Roll eyes

It was something like function-3, once I'd done that everything sprang into life and started working. There's also a bunch of command-line tools for messing with wireless:

You can also switch the wireless power on/off with the command: iwconfig eth0 txpower on (where eth0 is the name of your wireless ethernet adapter).

Sorry this is so long after your post, I assumed someone else would have a better reply than I do!

Thanks, Jeeves.

Yes, I'll check out those wireless commands. I'm experimenting with various distros, including Ubuntu, but they just don't recognize the router, although now I've gotten them to see the card in my PC.
