What are you using for Wifi? We use Aruba and Unifi. If I do Unifi, everything has to be on one channel, which leaves 2 options for Sonos. If I do Aruba, I let Adaptive Radio management decide where to put the AP's. It has never had the same channel on Sonos when I look at the history. You could always put Sonos on 6, then put your AP's on 1 and 11.

Sonos very rarely needs to be rebooted. I would have an IP Power strip and plug the Root Bridge into an IP Controllable outlet if you are worried about it.
