During initial setup, the WiFi light flashes green quickly, and then slowly. After pressing the button for 5 secs, the light flashes alternately green and yellow as in the instructions.

Then, on an IPad 2 the fidelio's own network appears in the list of networks, but when I tap on it I get an "unable to connect" message, following which the fidelio's network disappears. Same every time. Same also when trying to connect from a PC.

Any ideas? My router uses the normal 802.11b/g.
