Thank you so far!
I figured out how use route and established to routes:
Destination Gateway Genmask
192.168.2.0 * 255.255.255.0
default 192.168.2.1 [don't know]
I hope the genmask is not necessary for this, because I don't remember
now. I had to boot Windows for writing this.
Unfortunetely I still can't connect to everything, neither the router
(has got a web interface) nor to any other internet server. Also a ping
to the router failes. But the wireless connection to the router is
established. I run ifconfig wlan0 up and didn't see any outputs but I
think that should work now. IP adress and netmask are shown correctly.
So where is the problem?
By the way I take it my NIC hasn't got any DNS servers. So it won't be
able to lookup
www.google.com and other hosts. Would you like to tell me
how to set up this?
Thank you for helping me
