I have 3 M1001s that I use to play the iTunes from my Mac in my home, and recently one has been quite problematic. It is connected via a computer jack to a Netgear router, with 2 other cords, one an RCA jack into my stereo receiver, the other the Sounbridge power supply. The problem unit is directly connected, the other two in other rooms away from my Mac are connected via Cat5 wiring which I had put in when I remodeled.
Problem: The unit keeps cutting out during use, with any of the following variations--> It powers up, goes to playlist, and then, upon pressing "play" for the first song, immediately reboots and goes through its "Let the music play!" start up. At other times, it plays for 20 minutes before doing that. And finally, a couple of times it's sent me a message saying "Too many users connected", and stymied my efforts to get around that.
On perhaps an unrelated note, I've checked "sharing" preferences on my iTunes and have seen "On, other users connected". I don't have Wi-Fi or Bluetooth enabled, so that kind of spooks me (I have Apple TV, an iPad, iPhone etc, but these are not powered up/connected at the time)
What I've done: Changed out to one of my other units. Same problem.
Restarted Mac.Unplugged modem, router, Soundbridge unit, plugged back in.
Head Scratcher: my other 2 Soundbridge locations (great room and MBR) are able to play without interruption. This tells me it's not a computer or router problem, no?
The power source and other connecting cords all seem to look OK. If it were just about going on Amazon and finding a new unit, I'd do that, but since I switched out the unit, I'm wondering if that's a waste of time. Maybe I should just buy all new power cord and/or computer jack cord for the unit?
