AIR WIFI not streaming

[Mohmm]

When you restarted did you power down and unplug everything. Sometimes I have found that necessary.

Not every time, because it reloads the firmware which takes a long time.

Have you looked at the Devialet information menus to see that the signal strength there correlates with that on the MacBook Pro and also on iStumbler and iiSIDDer if you use those?

As I mentioned, I looked at the information menus and s/n was right. In fact, the D is not located very far from the router.
