I downloaded 5.01 yesterday and shocked that my ipw2200 is not working.
On 4.02 (and maybe 5.00 CeBit too), it was working just fine.

I tried "netcardconfig", "ifconfig eth0 up", and some of the utility programs under the Knoppix menu, but no avail.

I post below the result of my "dmesg" and "lspci -v".
Seems like it's crapping out at some firmware compatibility ?
How do I look up on the error code ?

Help !

"sudo lspci -v"
