Wi-Fi 7 vs Wi-Fi 6
Wi-Fi 7 roughly doubles Wi-Fi 6's channel width, adds a third 6 GHz band, and introduces Multi-Link Operation for steadier latency. In practice, whether you'll notice depends far more on your internet plan and devices than on the spec sheet.
| Spec | Wi-Fi 6 | Wi-Fi 7 |
|---|---|---|
| IEEE name | 802.11ax | 802.11be |
| Released | 2019 | 2024 |
| Max (theoretical) | 9.6 Gbps | 46 Gbps |
| Real-world phone | ~1 Gbps | ~2–5 Gbps |
| Bands | 2.4 + 5 GHz | 2.4 + 5 + 6 GHz |
| Max channel width | 160 MHz | 320 MHz |
| Modulation | 1024-QAM | 4096-QAM |
| Multi-Link (MLO) | No | Yes |
The three differences that matter
1. 320 MHz channels (double the width)
Wi-Fi 7 can use 320 MHz-wide channels on the 6 GHz band — twice Wi-Fi 6's 160 MHz. Wider channels move more data per transmission, which is where the headline speed jump comes from. You only get this on the 6 GHz band, and only with Wi-Fi 7 devices.
2. Multi-Link Operation (MLO)
This is the genuinely new trick. A Wi-Fi 7 device can talk on two bands at once — combining them for more speed, or hopping to whichever band is cleaner for lower, more consistent latency. Wi-Fi 6 can't do this at all. It's the biggest real-world win for gaming and video calls.
3. 4096-QAM (denser signal)
Wi-Fi 7 packs about 20% more data into each transmission than Wi-Fi 6 — but only when your device is close to the router with a strong signal. Across the house, this advantage fades.
Real-world speed: the honest version
On paper Wi-Fi 7 tops out around 46 Gbps versus Wi-Fi 6's 9.6 Gbps. On a real phone you'll see nothing close to either. What matters is that a typical Wi-Fi 7 phone can pull several gigabits in good conditions, versus roughly one on Wi-Fi 6 — which only helps if your internet plan exceeds those figures. On a sub-gigabit connection the two feel identical.
Which should you buy?
- Stick with Wi-Fi 6 if your plan is under a gigabit and your Wi-Fi feels fine.
- Consider Wi-Fi 7 if you're on multi-gig, have a device-dense home, game competitively, or are buying a router you want to last five years.
