While I was out for an hour this morning, my Bolt switched itself from MOCA to wifi, abandoning the two minis in my house. My wife was watching tv on the mini when I left this morning. When I got back the minis were giving an error that they couldn't find the bolt. Everything was working fine this morning, and I didn't have any network issues (that I know of) Rebooted the Bolt, rebooted the minis and everything seemed to come back to normal on the MOCA. Any ideas what would have caused the Bolt to turn on wifi and abandon MOCA? Is there a way to prevent it from doing this in the future? The way my house is laid out, one of the minis is too far away from wifi to be usable, so I can't have it switching itself to wifi.
