The short version
eero 6+, throughput 640Mbps at 5m, 210Mbps at 20m — Router Placement: The Free Upgrade Most People Skip. Measured on hardware rather than argued from theory, on a device we rate for setup is genuinely five minutes.
Moving a router two metres frequently beats spending hundreds on a faster one, because physics dominates specification.
Why this matters: Coverage complaints are usually placement problems, and placement costs nothing to fix.
What is going on underneath
Wi-Fi radiates outward from the antennas, roughly in a flattened sphere, and is absorbed by water, metal and masonry. A router in a floor-level cupboard beside a boiler is fighting all three. Height helps because it clears furniture; central placement helps because coverage is wasted outdoors otherwise. The 5GHz and 6GHz bands are absorbed far more than 2.4GHz, so the higher the band the more placement matters. Mirrors, aquariums, foil-backed insulation and radiators are the specific obstacles that surprise people.
In daily use
Take the eero 6+ as a worked example. Throughput on the second hop fell to 210Mbps, the largest drop we measured. That is the difference this makes once you stop reading specifications and start using the thing.
| Specification | eero 6+ |
|---|---|
| Standard | Wi-Fi 6 dual-band |
| Throughput | 640Mbps at 5m, 210Mbps at 20m |
| Ports | 2x GbE per unit |
| Coverage | 140m² per unit |
| Backhaul | 5GHz shared |
| Setup time | 5 minutes |
The same concept across four devices
One worked example is an anecdote. Here is how the figure that drives this behaviour actually varies across the hardware we have measured in this category — same test, same conditions, so the spread is real rather than an artefact of who reviewed what.
| Model | Standard | Price | Our score |
|---|---|---|---|
| eero 6+ | Wi-Fi 6 dual-band | £139 | 3 / 5 |
| Eero Max 7 | Wi-Fi 7 tri-band | £599 | 4 / 5 |
| TP-Link Deco XE75 | Wi-Fi 6E tri-band | £229 | 4 / 5 |
| Asus RT-BE88U | Wi-Fi 7 dual-band | £399 | 4 / 5 |
What good actually looks like
It helps to have a number in mind before you start comparing. Across the networking Gear we have measured, the useful thresholds are the ones where a difference stops being visible: below them you notice, above them you are paying for a specification rather than an experience. The eero 6+ reports Wi-Fi 6 dual-band for standard, which sits comfortably on the right side of that line, and 640Mbps at 5m, 210Mbps at 20m for throughput. Treat anything materially below those as a real compromise and anything materially above as a number you are unlikely to feel.
How to check this on your own device
- Reproduce the conditions rather than trusting a one-off reading — run the same task three times and take the average.
- Note the figure your device reports and the figure it actually achieves; on the eero 6+ those diverge under sustained load.
- Change one variable at a time. Brightness, background sync and ambient temperature all move this number independently.
- Compare against the manufacturer’s stated figure and treat any gap as the cost of real-world conditions, not as a fault.
- Repeat after a firmware update — this is one of the numbers that moves without an announcement.
How to use this when buying
Put the router as central and as high as the cabling allows, clear of metal and water, before buying anything.
Placement changes results more than a generation upgrade does, and it is free.
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.
