I posted once before witb much less information. Essentially, I'm trying to get a linksys wmp54g wireless card to work with knoppix. I've tried a few things and read several forum posts. I'm still lost. It may be I just don't know enough.

When I try to start knoppix 5.0.1 (CD - KNOPPIX_V5.0.1CD-2006-06-01-EN.iso) and it reaches the networking part, it says:

eth0 detected
dhcp broadcasting for ip
udevd - event[3258]: wait for sysfs: waiting for 'sys/class/net/eth0/device/driver' failed

Nothing seems to happen after that. I'm stuck.

I tried starting with the nodhcp cheat code.

It goes a little further, but the last thing I see is this

probing/loading agp modules udevd_event[3391]: wait for sysfs: waiting for '/sys/c;ass/net/eth0/device/driver' failed.

- - - - - - - - -

So, I downloaded version 4.0.2 (CD - KNOPPIX_V4.0.2CD-2005-09-23-EN.iso)
It also hangs if I start without the nodhcp code. Instead of returning an error, it just goes off and never returns.

It does start with nodhcp.

I tried some things I found in a forum

I then run iwconfig eth0 essid "my ssid"
That seems to work.

iwconfig returns this

lo no wireless extension

eth0 RT2500 Wireliess ESSID: "My ssid"

I try pump -i ath0.
It hangs. No error. Nothing.

I also tried configuring the network card from the knoppix menu to no avail. That ends up hanging.

The relevant (I think) output from lspci -v is
