I am having consisitnent issues with playing music from my Itunes folder, on an external drive. I get error message 1002 as well as the "network speed insufficient to maintain buffer playback". All goes back to normal when I do a complete reset of modem, router, bridge, wired sonos players, then wireless sonos players. But the problem returns the next day. Can you (Sonos) please advise me on how to address this issue? I recently replaced an older Airport Extreme router with the latest generation of Airport Time Capsule. Sonos system performance was mostly reliable until now. I was very careful to use the same settings on the new router.
