I have followed the instructions on the CD: connected the speaker to the router, switched on the router. After 2 minutes I am informed that the unit cannot be identified. I've tried playing with the configuration of Windows firewall, I've tried switching it off altogether, I've tried rebooting the computer. The result is always the same. Can someone help me? Has the fact that I bought the speaker in the USA and I'm trying to get it to work in Italy got anything to do with it? Are wi-fi protocols different on the other side of the Atlantic?

My operating system is Windows Vista Home Premium version 6 service pack 2.

The router is an Atlantis Netfly Ap4 WN, Wireless N 150Mbps, Multifunction Access Point (Model code: AO2-AP4-WN).
