Hello,

Which eth? shows up as WLaN ? eth0 or eth1 ?

Right. The easy way out is to connect via ethernet and configure  
everything (DNS-server, gateway... ). Then edit /etc/network/interfaces  
and replace eth0 with eth1. It should look a bit like like this:

auto eth0
iface eth0 inet static
         address 192.168.1.5
         netmask 255.255.255.0
         network 192.168.1.0
         broadcast 192.168.1.255
         gateway 192.168.1.1
         # dns-* options are implemented by the resolvconf package, if  
installed
         dns-nameservers 192.168.1.1

(192.168.1.1 is my DSL-Router, my WLAN is eth0 as the module for the  
Ethernet port is not loaded)

afterwards run (as root):
ifconfig eth0 down
ifconfig eth1 down
/etc/init.d/networking restart

That's easy: run "route" as root.

I can report that my R51 is using a Intelbased IPW2200 WLAN card and not a  
Atheros. But the principe is the same. Dynamic switching between WLAN and  
Ethernet based on connection status is a bit tricky (not yet working)
