NETGEAR Orbi 750 Series mesh has weak signal or dead zones

The checks in more detail

A satellite that is too far from the router has a weak backhaul and gives a weak signal in its room, however close the device is to it. Check what the Orbi app or the satellite's light says. A satellite light that shows a weak or no connection to the router means that the backhaul is poor; move the satellite closer, within a room or two of the router and with fewer walls between them, and check the light again. The satellite should sit halfway between the router and the dead zone, not in the dead zone itself.

Place each unit in the open, off the floor, away from metal, mirrors, microwaves and other electronics, and not inside a cabinet. A satellite behind several thick walls or a floor often needs to be one level closer. If one satellite does not cover a whole house, add another, positioned so that each is within good range of the one before it, but remember that each hop costs speed. The best fix for a stubborn room is a wired backhaul: run an Ethernet cable from the router or a switch to the satellite, which gives a rock-solid link and frees the wireless backhaul.

Check that devices are connecting to the nearest node, since a device clinging to a distant node is a roaming issue; restarting its Wi-Fi forces a new choice. Remember that thick masonry, foil insulation and long, narrow houses are difficult. A satellite's firmware should be updated through the app. A change of channel or a restart of the system sometimes helps. If an Orbi satellite will not connect even close to the router, contact Netgear with the RBR750 serial number.
