Draytek 130 nicht funktoniert

My line was finally activated on Thursday, but I am still not connected to the internet. I have a Draytek 130 and I cannot access its interface to connect it to my Asus router. I input the username and password provided by o2 directly on the Asus, but there is still no internet connectivity. I just hope I have the correct cables, I bought the Draytek used and I had to find a TAE cable with RJ11. Any help would be greatly appreciated!
