WLAN installation anything but straightforward

We bought the CLP315w for the WLAN function.
I was due to other reviews, already prepared for the installation everything would be easy.
I have largely used the information from Johnny Fiamma here (5 Stars). Router: Fritzbox WLANBox 7113, Win XP SP3
But it was not.
Therefore, another important note:
The problem with us is that the name of the WLAN with special characters or spaces was peppered. Once these have been removed, and suddenly found the printer and the WLAN could be easily configured.
Alternatively, it may also be that you have to WPA2 with CCMP (Neudeutsch for PSC) change the encryption so that wireless can be found.

To print image / consumption I can tell currently little. But the recent printouts all looked very good.

Therefore, a star deduction for the time-consuming and cumbersome WLAN installation.
