Vista e Router Wireless Troubles

I've recently buyed a Siemens notebook, with Vista Home Premium. Then I've
buyed a Siemens Gigaset SE567WLANDSL, a wireless modem tested by Siemens.
Vista see the router on Wireless connection, but when I try to connect with
him, Vista give me an error in the authorization protocol.

I try some different authorization protocols, setting them on router and on
vista, but errors remains.
Here the error logs (http://merlinox.googlepages.com/erroriWirelessVista.zip).

Thanks for your attention.
