Vista - Connect to WiFi

When I try to connect to my home wireless network I get the message that
connection failed for an uknown reason.

The computer finds and displays the wireless network correctly but just
fails to connect.

Any suggestions as to what might be the problem? The modem? The operating
system? The hardware? Settings?

I am using RC1 and an MSI Dual Net card with the native Vista wireless
driver. the Mother board is an A8N32-SLI Delux with and AMD X2 4400

I was getting this for a while until I updated the firmware in my Draytek
2600g router.
After this all was well.
