Asus RT-BE88U vs Orbi RBE973: Is the Orbi RBE973 Worth £1100 More?
Asus RT-BE88U or Orbi RBE973? We compare price, measured performance and real-world trade-offs to work out which is the better buy.
Tech Daily Review Desk
The short answer
Asus RT-BE88U 14 minutes, Orbi RBE973 12 minutes — the same test, run the same way. Where they part company is who they suit: the Asus RT-BE88U is the one to get if you are anyone who wants to configure their network rather than accept defaults, the Orbi RBE973 if you are very large homes with a multi-gig line and no budget ceiling.
Price difference: The Asus RT-BE88U undercuts the Orbi RBE973 by £1100. That gap only matters if the extras below are ones you will actually use.
Specifications side by side
| Specification | Asus RT-BE88U | Orbi RBE973 |
|---|---|---|
| Price | £399 | £1499 |
| Our score | 4 / 5 | 3 / 5 |
| Standard | Wi-Fi 7 dual-band | Wi-Fi 7 quad-band |
| Throughput | 1.4Gbps at 5m, 420Mbps at 20m | 1.9Gbps at 5m, 710Mbps at 20m |
| Ports | 1x 10GbE, 1x 2.5GbE, 4x GbE | 1x 10GbE WAN, 1x 10GbE LAN, 3x 2.5GbE |
| Coverage | 260m² single unit | 250m² per unit |
| Backhaul | AiMesh compatible | Dedicated 6GHz |
| Setup time | 14 minutes | 12 minutes |
How we tested
Every figure quoted above comes from the same protocol, run on every unit in this category. This one spent two weeks carrying the whole household, with the previous router boxed. A 2Gbps fibre line, a fixed Wi-Fi 7 laptop client, and the same four positions in a 180m² brick house on every system.
| What we measure | How |
|---|---|
| Throughput at 5m | iperf3 for five minutes, same room, line of sight, averaged across three runs. |
| Throughput at 20m | The same test two floors away through brick, which is where marketing figures collapse. |
| Roaming | Walking a fixed route with a continuous ping, counting dropped packets at each handover. |
| Setup time | From opening the box to a working connection, timed, using the app the maker intends. |
| Device load | Forty-two devices connected, then the 20m test repeated to see what congestion costs. |
We deliberately do not report combined band totals such as "BE22000", which no single client can ever reach.
The honest caveat: Every figure here is specific to one brick house. Timber-framed homes will see materially better range.
Where the Asus RT-BE88U wins
- More manual control than any consumer router at this price
- Eight LAN ports removes the need for a switch
- Free lifetime security features with no subscription
It also has the edge on the intangibles: it was the only router we tested that exposed per-device QoS properly.
Where the Orbi RBE973 wins
- The fastest throughput we measured at every distance
- A genuinely dedicated backhaul band, not shared
- 10GbE in and out
And in day-to-day use, it is the only system here that saturated our 2Gbps line wirelessly.
The trade-offs
Neither is flawless. The Asus RT-BE88U has one clear weak point — the interface assumes you know what a VLAN is — and the Orbi RBE973 has its own: £1,499 is more than most people spend on a laptop. Weigh those against how you actually work rather than against the spec sheet.
The value case
The Orbi RBE973 costs £1100 more and scores 1 point higher — roughly £1100 per point of difference. Whether that is good value depends on whether the extra buys you the fastest throughput we measured at every distance, or only a number. In our testing it is the former, but only just.
If neither quite fits
Look at the Eero Max 7 at £599 — it scored 4 out of 5 and suits large homes where setup simplicity matters more than tuning. If the budget will not stretch, the eero 6+ at £139 is the cheapest option in this category we would still put our name to.
Living with each of them
On paper the gap looks like a specification difference; in use it is a habits difference. With the Asus RT-BE88U the thing you adjust to is the interface assumes you know what a VLAN is, and you do adjust — within a week it stops registering. Its standard (Wi-Fi 7 dual-band) is the part you stop thinking about. The Orbi RBE973 asks for a different accommodation: £1,499 is more than most people spend on a laptop, against a standard of Wi-Fi 7 quad-band that holds up better than the number suggests. Neither compromise is severe. They are simply different, and which one you would rather not think about is a more useful question than which is objectively smaller.
Which one ages better
Both launched in 2024, so neither starts with a support-window advantage. The other half of ageing is the weak point you already know about: the interface assumes you know what a VLAN is on one side, £1,499 is more than most people spend on a laptop on the other. Weaknesses of that kind do not improve with firmware, so assume you are buying them for the life of the device and price the decision accordingly.
Our recommendation
For most people we would take the Asus RT-BE88U, which scored 4 out of 5 in our testing against 3 for the other. That said, a score is a summary, not a substitute for knowing what you need.
Buy the Asus RT-BE88U for more manual control than any consumer router at this price. Buy the Orbi RBE973 for the fastest throughput we measured at every distance.
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.
