How do I stop KWallet from asking my password to let the system connect to WiFi?

I've just switched to KDE and although I feel interested in exploring the opportunity to use KWallet for all kinds of cryptographic key/certificate files and some browser passwords perhaps if it can do that (I don't know yet), I absolutely don't want to enter my password every time I want to connect to WiFi. In fact I have to enter my password twice at the boot time now - to log-in and to get WiFi connected right after that and I find this is very annoying. Is it possible to disable KWallet WiFi passwords management and let the network selection applet (or whatever it is) remember it itself or to configure KWallet to just stop requiring explicit authorization for things this simple?
