I have trouble getting my Ethernet card to work. It is a 3C900. I connected it using a twistet pair cable to my router. Starting Windows everything works fine, so it shouldn't be Hardware.

I am working with Knoppix 3.2 which is based on Linux kernel 2.4.22.

I can ping on myself, but when pinging my gateway I get:
====
PING 192.168.0.1 (192.168.0.1): 56 data bytes

--- 192.168.0.1 ping statistics ---
19 packets transmitted, 0 packets received, 100% packet loss

After that ifconfig says:

====

dmesg says (including the audio device working on same interrupt):

The silly thing: It states 10base2 even if I insert in modules.conf:

====
options eth0 debug=1 options=0 full_duplex=1

What can I do else?
