Wi-Fi 7's three big features: 320 MHz channels, 4096-QAM, and Multi-Link Operation (MLO). What each actually delivers in your home in 2026 vs what the marketing claims.
The marketing claim:
"2x faster speeds via double-width channels. Wi-Fi 7 delivers 4.8 Gbps on a single device."
The honest reality:
320 MHz channels are only available on the 6 GHz band, which requires line-of-sight at close range. At two walls distance, the 6 GHz signal degrades to the point where 160 MHz or even 80 MHz are more reliable. Most devices (including iPhone 16) cap at 160 MHz anyway. You need a specific combination of Wi-Fi 7 client device, close proximity, and 6 GHz signal to see the full benefit.
Channel width reality check
Wi-Fi 6 used 1024-QAM; Wi-Fi 7 uses 4096-QAM. Each step packs more data into the same radio signal by using more distinct amplitude and phase states. The catch: higher QAM requires a stronger, cleaner signal to distinguish those states reliably. 4096-QAM needs roughly 4-6 dB better signal-to-noise ratio than 1024-QAM to operate reliably.
In a typical home: at close range (same room, 2m), your device gets 4096-QAM and the 20% throughput bonus. Through one wall (5m), the radio falls back to 1024-QAM or 256-QAM. Two walls away, the QAM level is the same as Wi-Fi 6. The 20% bonus is real and measurable at close range; it disappears at household distances through walls.
RTINGS called it the "disappointing truth about MLO": most 2026 consumer implementations are STR-MLO or eMLSR, not true link aggregation.
What marketing claims:
What actually works in 2026:
The 1 ms latency claim requires lab conditions: a single client, line-of-sight, both bands fully clear. Outside the lab, the independent testing has not reproduced a latency benefit at all. RTINGS found that turning MLO on or off made no measurable difference to throughput, latency or connection stability against using the 6 GHz band on its own, and Tom's Hardware reports no significant advantage from an MLO network versus a single band, with the non-MLO network often doing better. Where MLO does demonstrably earn its keep is the case it was designed for: lab work by Alethea Communications Technologies shows it holding latency and throughput steady when one band is deliberately jammed. So the mechanism is real, and the consumer implementations are not there yet.
Practical upshot: do not pay a premium for MLO. If your router offers an MLO network as its own SSID, test it against a plain 6 GHz network on your own hardware and keep whichever is actually better. More detail on the gaming case: does MLO cut latency for gaming?
Wi-Fi 6E (2022-2023) added the 6 GHz band to Wi-Fi 6. Wi-Fi 7 (2024-2025) adds 320 MHz channels, 4096-QAM, and MLO on top of 6 GHz. If you bought a Wi-Fi 6E router in 2024, you already have most of the practical benefit.
