After various PC problems now fixed I find that my WADM no longer detects the WAC7000 center which means I cannot manage the music content. It picks up the Stations that I have around the house, but that doesn't help much. The basic troubleshooter can only suggest switching off the firewalls, which is not the problem (I don't think). It doesn't even detect the Center when I hook it up with an Ethernet cable. Does anyone have any suggestion?
