The dsl cable is working, I can access the internet through the router to write this. My mobile phone also sees the wifi. It is Android, but it only says 'obtaining ip address' and never gets any further.
So I'm thinking, I need to switch something in the router. But as you say, there is no 192.168.1.1 address in the ifconfig. Why not??
