Orbi RBE973: A Smart Device Will Not Join the Network
A Smart Device Will Not Join the Network on the Orbi RBE973: what we found on our own £1499 unit, the checks that resolve it, and when it is a warranty case rather than a setting. A plug, bulb or came...

What you are seeing
Orbi RBE973, throughput 1.9Gbps at 5m, 710Mbps at 20m. A Smart Device Will Not Join the Network is the fault being chased here, on a unit bought and tested rather than loaned. It is genuinely good at a genuinely dedicated backhaul band, not shared, and the thing that repeatedly cost it marks was the nodes are large and unattractive.
A plug, bulb or camera fails setup repeatedly, while phones and laptops connect without trouble. That is the behaviour; what follows is how it tends to present on this particular Netgear, and what to rule out first.
Before you start: Work through these in order. The first two resolve the majority of cases and neither risks your data.
Start here
| Check | Why it matters |
|---|---|
| Is it reproducible? | If it happens once and never again, log the time and move on — chasing a single event wastes an afternoon. |
| Has anything changed? | A firmware update, a new app, a new accessory. The cause is almost always the most recent change. |
| Does it happen on a fresh restart? | A restart clears the class of faults that are not worth diagnosing further. |
| Is it under warranty? | The Netgear warranty makes some of the steps below unnecessary — check before you start pulling things apart. |
Step by step
- Check whether the device is 2.4GHz only, which most smart-home hardware still is.
- Temporarily disable band steering, or split the bands onto separate names for the duration of setup.
- Set the 2.4GHz channel width to 20MHz, which several classes of device require to associate at all.
- Disable WPA3 and use WPA2 during setup, as older chipsets cannot negotiate WPA3 or mixed mode.
- Turn off client isolation and AP isolation, which silently block the discovery step.
- Move the device within a few metres of the router for setup, then return it to its intended position.
If none of that worked
If the device joins a phone hotspot but never the router, the router security or band configuration is incompatible.
Keeping it from coming back
Keep a 2.4GHz-only WPA2 network with a distinct name for smart-home devices. It removes this whole class of problem.
The usual cause
In our experience this is rarely a single fault. The common pattern is an accumulation: a background process that was fine on its own, a setting changed months ago, and — on the Orbi RBE973 specifically — £1,499 is more than most people spend on a laptop, which narrows the margin before anything else goes wrong. That is why the steps above start with the cheap reversible checks: on a Netgear device the expensive diagnosis is almost never the one you needed.
When it is a hardware fault
If the behaviour persists after a factory reset, it is worth raising with Netgear under warranty rather than working around it. Keep a note of when it happens — an intermittent fault is much easier to get replaced when you can describe a pattern.
Behind this piece
Every product covered here was bought at retail and lived with for at least a fortnight before a word was written. Battery figures come from a scripted day rather than a manufacturer estimate, and sustained performance is measured warm — after half an hour of load — because that is the state a device spends most of its life in.
Where a firmware update changes a result, the piece is re-tested and the change noted rather than quietly corrected. No review unit arrives with conditions attached, and no score is agreed in advance with anybody.
Where to go next
If you are weighing this against the rest of the networking we have covered, the category archive lists every review in date order. The closest comparisons we have published are Orbi RBE973: Devices Will Not Stay Connected to the Mesh and Orbi RBE973: Speeds Far Below the Line You Pay For.
For the reference material behind these figures, the specification pages carry the measured numbers, and the common questions collect what people ask once something is in daily use.
