Polk Audio Omni A1 - Troubleshooting

[nuvision]

I am having connection issues with my Polk Audio Omni A1.  I launch the music and it will play at times for an hour without interuption.  Sometimes even more but randomly cuts out at one point and we have to strt it up again.

Has anyone heard of this and can you offer up any suggestions on how to fix it?

I can't be sure however I don't think it's the connection to the A1 itself that's the issue.  Yes on rare occations I lose connection from the box to the network but for the msot part it's stable.

Thanks.
