first I wanted to say that there is eth1 but since it's wlan I didn't think it would mather

and when it comes to ping

pinging www.knoppix.net gave:
Unknown host

and pinging the ip gave: Network is unreachable

And when I put it into iceweasel it showed

Firefox can't find the server for www.knoppix.net

and Unable to connect
firefox can't establish a connection
for the ip

there might be something really elementar I have overlooked since I'm not really good with computers
