Problems with 5 GHz speakers losing their connection to Orbi mesh system

Thanks for the response - I don't believe the satellite is the cause of the problem; at Yamaha Support's suggest earlier this week, I tried turning off the satellite and leaving it off, and it didn't make a difference: the speakers still got disconnected. It's not really feasible for me to move the satellite, anyway - I need it upstairs for my home office and other wireless devices.

It is interesting that you ask about interference - I hadn't really thought about that, but it's possible. In fact, this very morning, I noticed that my DirecTV (Genie 2, connecting wirelessly to a Genie Mini in the same room) kept cutting in and out, while the speakers were on. That makes me wonder: could the DirecTV wireless be interfering with the speakers? The DirecTV was not on this week while I was troubleshooting the speakers, so I hadn't considered it, but it's possible. I've turned off the speakers for now, to see if that helps the DirecTV; if it does, this seems like a likely culprit (at least for today).

I'll try changing wireless channels on the 5 GHz next, to see if that helps. I do have implicit beamforming on; I'll try turning that off too. Thanks for the suggestions!
