Review on ALLICAVER Wall Mount Netgear Orbi - Sturdy Metal Stand Holder for Orbi WiFi Router RBS40, RBK40, RBS50, RBK50, AC2200, AC3000 - Compatible (1 pcs) by Gary Revils

Ideal for mounting Orbi. Keep in mind that the metal is soft and bends easily, but once installed this is not a problem. I used the included cheap plastic anchors to attach this to the drywall and they work great. I chose these from the available acrylic versions as acrylic tends to attract dust. With small dimensions and cutouts, I don't think this metal mount will block the signal to any significant level. You can paint it to match your wall color if you wish, although it goes well with the Orbi as is. My next step is to route the cables through the wall. I'll be using this wall plate behind the orbi for a neat finished job. https://smile.amazon.com/gp/product/B07DNTWRX5/
