I recently added a Mini Vox to my two Bolts and three Premieres, as I needed something small and quiet in the bedroom. One Bolt is on TE3 and the other is on TE4. I started the mini on the TE4 Bolt and used the MoCa bridge on the Bolt to feed the Mini. Decided that text was too small in the bedroom even with a 37" TV, so I switched the Mini to the TE3 Bolt. After the Mini downgraded, I began to have internet connectivity issues. The cable modem was getting signal, but the router was dropping internet frequently. After a couple of calls with Midco cable, and resetting the router (and even changing from a Google router to a Linksys Velop), I had to face the fact that the problem was in my network. I started with everything disconnected and added rooms back in, and sure enough, there was a problem when both Bolts were on the LAN. Both were set up as MoCa-ethernet bridges, though I don't recall setting them up that way. Once I disabled the MoCa bridge on the TE4 Bolt (the one no longer feeding the Mini), all was well again. I couldn't find anything on the forums about this, and whether setting up a different Bolt for a Mini could also change the bridge setting. Or perhaps it was a senior moment? I can say that having two units serving as a bridge is not a good thing.
