Learn · Wi-Fi 7 explained

Wi-Fi 7, minus the press release.

Three real improvements, one honest caveat each, and a comparison table with numbers you can check against the datasheets. By the end you'll know whether your house needs it — plenty don't, and we'll say which.

WHAT CHANGED 01

The three things that are actually new

Everything else on the spec sheet is a refinement of these. Each one is real; each one has a condition attached.

320 MHz CHANNELS

Double-width lanes on 6 GHz

Wi-Fi 6 topped out at 160 MHz channels. Wi-Fi 7 doubles that on the 6 GHz band — twice the data per transmission, which is where the 5.7 Gbps headline comes from.

THE CATCH6 GHz has shorter range and hates walls. The wide lane exists in the same room as the AP; two rooms away you're back on 5 GHz.
MLO

Multi-Link Operation

A device can use 5 GHz and 6 GHz simultaneously instead of picking one — lower latency, and a seamless fallback when one band degrades. This is the feature that makes video calls feel different.

THE CATCHBoth ends need Wi-Fi 7. Your 2023 laptop doesn't do MLO no matter what AP you hang.
4K-QAM

Denser signal encoding

About 20% more data packed into the same transmission versus Wi-Fi 6's 1K-QAM. A free efficiency win on top of everything else.

THE CATCHDenser encoding needs cleaner signal. It works near the AP; at range, the radio steps down to coarser encoding automatically.
NUMBERS 02

Generation by generation

PHY rate is the lab number; the real-world column is what a single modern client sees a room away from the AP, on our bench, with the usual neighbors' networks interfering.

GenerationBandsMax channelPeak PHY rateReal-world, one room away
Wi-Fi 5 (2014)5 GHz80 MHz3.5 Gbps200–400 Mbps
Wi-Fi 6 (2019)2.4 + 5 GHz160 MHz9.6 Gbps400–700 Mbps
Wi-Fi 6E (2021)2.4 + 5 + 6 GHz160 MHz9.6 Gbps600–900 Mbps
Wi-Fi 7 (2024)2.4 + 5 + 6 GHz320 MHz46 Gbps0.9–1.8 Gbps

Note the gap between the 46 Gbps headline and the real-world column. That headline assumes 16 antenna streams; phones and laptops have 2. The honest pitch for Wi-Fi 7 is “your internet plan becomes the bottleneck” — which, for a gigabit plan, it does.

VERDICT 03

Should you buy it?

YOU HAVEWi-Fi 5 gear, or anything described as “the router from the ISP”
VERDICTUpgrade. You'll feel it on day one, and Wi-Fi 7 pricing now starts at $99 — there's no reason to buy into a previous generation.
YOU HAVEWi-Fi 6 that works fine, no gigabit plan, no Wi-Fi 7 client devices
VERDICTKeep it. Seriously. Your devices can't use MLO yet and your internet plan can't fill a 160 MHz channel, let alone 320. Revisit when the laptop gets replaced.
YOU HAVEGigabit+ fiber, new devices, all-day video calls, or a network being built from scratch
VERDICTBuy Wi-Fi 7. New builds especially — the price delta over Wi-Fi 6 has collapsed, and the U7 Pro at $189 is the default answer for a reason.

One practical note for the “buy” column: a Wi-Fi 7 AP can move more than 1 Gbps of traffic, so give it a 2.5G uplink — the U7 Pro has the port; make sure the switch does too. The PoE calculator flags this when you mix gear.

QUESTIONS 04

The follow-ups everyone asks

Will my old devices still work on a Wi-Fi 7 network? +

Yes — fully backward compatible. Old devices connect at their own generation's speed and don't slow modern ones down the way they did a decade ago; airtime scheduling improved precisely for mixed households.

Is Wi-Fi 7 better at range, or just speed? +

Mostly speed and latency. Range is governed by physics and transmit-power rules that didn't change. If the back bedroom has no signal today, the fix is AP placement or a second AP — not a newer standard. That's a coverage planning problem, and the planner is free.

Do I need new cabling? +

Existing Cat5e/Cat6 runs carry 2.5G fine at home distances, so usually no. The thing to check is the switch: a gigabit port caps a Wi-Fi 7 AP at 1 Gbps regardless of what the radio can do.

What about 6E — is it a sensible middle step? +

In 2026, no. Wi-Fi 7 hardware reached 6E pricing, so 6E is the worse deal for the same money. It made sense for about eighteen months; that window closed.
