I bought the router Fritz!Box 7490 in the hope that I get better WLAN connectivity at home.



However, when I need to configure it so that it takes the o2 internet connection, it needs a 15-digit PIN. However, I only have a 10-digit PIN in the documentation provided by o2. 



The question is: how do I get a 15-digit PIN or how do I get the fritzBox router working with the 10 digit PIN that I already have?



Thank you
