Does Wi-Fi 6 or Wi-Fi 7 Actually Have Better Range?

The box says better range. The review says better range. Then the router arrives, the back bedroom is exactly as dead as it was, and you are out three hundred dollars.

Here is the honest version. Wi-Fi 6 and Wi-Fi 7 are genuine engineering improvements, and almost none of that improvement is range. Knowing which parts are real tells you when an upgrade is the right purchase and when your money belongs somewhere else entirely.

Range is physics, and the physics did not change#

Three things set how far a Wi-Fi signal reaches, and no version number touches any of them.

Transmit power is capped by regulators, not by the standard. A consumer router puts out somewhere around 20 dBm — roughly 100 milliwatts — and a Wi-Fi 7 router puts out the same, because the legal ceiling is identical. Nothing in the newer standards asks for more power.

Your phone is the weaker end anyway. Handsets transmit at roughly 13 to 15 dBm, well below the router. In most homes the uplink fails before the downlink does, and a new router does nothing about the radio in your pocket.

A 5 GHz wave attenuates the same regardless of generation. The same brick wall costs the same 10 to 16 dB whether the frames crossing it are 802.11ac or 802.11be. Path loss is a property of frequency and material, not firmware — the honest indoor distances are in how far Wi-Fi actually reaches.

Put together: swapping generations moves the boundary where your signal falls below the usable -67 dBm mark by a few feet at best. One interior wall costs you more than the entire upgrade gains you.

What each headline feature actually does#

Read that column on the right again. Two entries are mildly positive, two are negative, and the rest are about capacity and efficiency. That is the whole story in one table.

One naming note, because the marketing is deliberately blurry: Wi-Fi 6 is 2.4 and 5 GHz, Wi-Fi 6E adds the 6 GHz band, and Wi-Fi 7 builds on 6 GHz with wider channels and MLO. Which band reaches which room is a bigger decision than which generation you buy, and it is covered in the 2.4 vs 5 vs 6 GHz comparison.

The two places a newer standard genuinely helps the edge#

Being fair to the engineering, there are two mechanisms that really do buy something at the far end of the house.

Longer symbols and better error correction. Wi-Fi 6 quadrupled the OFDM symbol duration and pairs it with stronger coding. In a cluttered room where signals arrive by several paths at slightly different times, that tolerance means fewer corrupted frames. Treat it as a small link-budget gain — a couple of dB, which is less than a single drywall partition.

Narrow resource units for small devices. OFDMA lets the access point hand a device a sliver of the channel roughly 2 MHz wide instead of the whole 20 MHz. Concentrating a device's power into a tenth of the bandwidth is a substantial improvement to that one transmission's link budget. It matters for battery-powered sensors reporting a few bytes; it does nothing for a laptop pulling a 4K stream, because that laptop needs the wide channel.

So yes, a Wi-Fi 6 access point may hold on to a marginal doorbell camera slightly better than an old one. That is the size of the effect. It is not a bedroom that gains coverage.

Wider channels and fancier modulation shorten your usable range#

This is the part that runs opposite to the marketing, and it is the reason some people get worse far-room performance after an upgrade.

Every doubling of channel width adds 3 dB of noise. A receiver listening across 320 MHz takes in four times the bandwidth of an 80 MHz channel, and four times the noise with it — about 6 dB worse signal-to-noise at the same signal level. Going from a 20 MHz channel to 320 MHz costs about 12 dB of margin. Wide channels are magnificent in the same room and actively counterproductive two rooms away.

Higher-order modulation demands a very clean link. Wi-Fi 6's 1024-QAM needs roughly 35 dB of signal-to-noise to run, and Wi-Fi 7's 4096-QAM needs more still. Those are same-room, line-of-sight conditions. At the -70 dBm edge of your coverage, both generations drop to the same low modulation rungs that Wi-Fi 5 used, and deliver the same speed there.

6 GHz travels less far than 5 GHz. Higher frequency means a couple more dB of free-space loss over the same distance and meaningfully worse wall penetration, and indoor power rules are tighter. A 6 GHz radio is superb one room away and often unusable two walls out. If your dead zone is at the far end of the house, 6 GHz is not the band that will rescue it.

The one qualification: in a congested apartment block, narrower channels plus BSS coloring plus an empty 6 GHz band can lift real throughput a great deal, because congestion is an airtime problem rather than a signal problem — see channels, neighbors and noise.

Where the gains really show up#

Upgrading is worth it for specific, nameable reasons. None of them is the far bedroom.

• Device count. OFDMA plus MU-MIMO turns a house full of phones, TVs, cameras and plugs from a queue into a schedule. A home with a few dozen connected devices feels the difference clearly.
• Dense buildings. BSS coloring stops your radio deferring to every neighbor it can hear, and the 6 GHz band is still mostly empty.
• Latency and consistency. Wi-Fi 7's MLO keeps a second band live, so a momentary problem on one link no longer stalls a call. Edges feel steadier, even though they are not further away.
• Battery life. Target Wake Time meaningfully extends battery on sensors and wearables.
• Peak speed near the router. If you pay for more than 500 Mbps and your router is several generations old, the upgrade is legitimate — but the gain lands in the rooms that were already fine.

That last point is the trap. A new router genuinely improves the good rooms, which makes the bad room feel worse by comparison — the pattern behind buying a new router and nothing changing.

Before you buy a new router: five checks#

Run these first. They take about ten minutes and they change the shopping list.

1. Read the actual signal level in the failing room, not the bars. Better than about -60 dBm means signal is not your constraint, and a faster router will not change what is wrong — full bars but still buffering covers what to look at instead.
2. Test beside the router. If the speed is bad there too, the bottleneck is your plan, your modem, or the router's routing performance, and generation is irrelevant to two of those three.
3. Count the walls on the straight line from the router to the failing room. Two or more dense walls, or a concrete floor, is a coverage problem no generation solves.
4. Check what your devices actually support. A Wi-Fi 7 router serving a house of Wi-Fi 5 phones delivers Wi-Fi 5 to those phones. The upgrade only pays when the clients can use it.
5. Try moving the router first. Getting it off the floor and out of a corner commonly buys 5 to 15 dB everywhere at once, which is more than any generational change will ever give you, and it costs nothing.

Plan the coverage, then choose the hardware#

Generation is a specification question. Coverage is a geometry question, and geometry is answerable before you spend anything.

Range Up exists to settle the geometry half before any money moves. Draw the rooms, set the material preset to match your construction, drop the router at its real position, and read the predicted level room by room. The only figure that matters is the one in the room that keeps failing.

If that room lands 20 to 25 dB under what it needs, no generation on the shelf closes a gap that size, and the useful next step is to name that room and let the planner sort candidate positions for a second radio by how much each one raises the level in it. That is a placement question answered in placement terms — the one thing a spec sheet cannot settle. If instead the room reads comfortably, reach was never the constraint — and a newer router may genuinely be the right buy, for capacity, in the rooms that already work. The app models your drawing on the device and never touches the network you are standing in, which is why it can weigh hardware you do not own. Map the failing room in Range Up before you read a single spec sheet, then check the extender and mesh placement rules.
