Configure the router to connect to ADSL. It should have a web or telnet
interface you can reach using the wired network ports.
Once that is done, you can worry about connecting to the wireless part.
At that point it is just wireless ethernet with probably dhcp to get the
settings from the router.
There is no ADSL settings at all on the linux side since the ADSL ends
at the router.
yes, this is the problem. Router uses address 192.168.1.1 to configure
it, but with browser or by ping 192.168.1.1 I don't get nothing
(unreachable).
