[solved]Can't get IP address with DHCP over wifi

I try to connect my laptop to a network via wifi (WPA). I'm connected and the router also says that there is a computer connected to wifi. But then DHCP time out. The ethernet connection is working fine and I have no problem to get an IP address with it. I have no idea what is wrong...

Re: [solved]Can't get IP address with DHCP over wifi

Ok it was in fact my fault. I did configure iwconfig like with a WEP connection, and it was WPA... Strangely it was not rejected, so I assumed it was connected...
