>It's funny but I have the feeling that the D-Link DP-G301 wireless printer server does not support WPA? If someone can confirm me that I'll just get rid of that part and upgrade for the new one.
That device has an embedded web server for configuration. You can access that site and check the wireless configuration to see if it supports WPA. There does not seem to be any updated firmware available from D-Link so what you see in the web config is all that's available.
These days even WPA is considered "busted" from a security POV. You should be using some flavour of WPA2 on all your wireless devices.
