Orbi RBR350 ethernet not working with wifi OK

Just wanting to post here saying I had the same problem almost 2 months ago now, found this post straight away and it's taken that almost 2 months (including my original ticket being closed after they said they'd get back to me with the workaround) to finally get the beta firmware sent to me which fixed the problem instantly. As a note to netgear support, it may pay to have this as your first point since it's a known problem with this model, especially when the user asks specifically for the firmware when they know it exists, or just take it out of beta since the most recent (broken) firmware was released well over 6 months ago.
