WiFi 6 vs WiFi 7: Which Router Should You Buy?
WiFi 7 is the newest standard, but is it worth it? Here is how WiFi 6, 6E and 7 compare and which one fits your home.
WiFi 6, WiFi 6E and WiFi 7 are the three current WiFi generations. Each adds speed and capacity, but the real benefit depends on your devices, your internet plan and the size of your home.
WiFi 6, WiFi 6E and WiFi 7 are the three current WiFi generations, each adding speed and capacity. The real benefit depends on your devices, your internet plan and the size of your home: internet under 500 Mbps with older devices means WiFi 6 is plenty, while gigabit or multi-gig fiber with the latest devices calls for WiFi 7.
Here is what changed between them in plain words, and which one makes sense to buy.
Comparison at a glance
| WiFi 6 (802.11ax) | WiFi 6E | WiFi 7 (802.11be) | |
|---|---|---|---|
| Bands | 2.4 and 5 GHz | 2.4, 5 and 6 GHz | 2.4, 5 and 6 GHz |
| Max channel width | 160 MHz | 160 MHz | 320 MHz |
| Key feature | OFDMA, better with many devices | Clean 6 GHz band | Multi-Link Operation (MLO), 4K-QAM |
| Real-world benefit | Busy homes | Less interference | Lowest latency, highest speed |
| Device support | Very wide | Phones and laptops from about 2021 | Newest phones and laptops |
The device-support row is the one I check before anything else.
What each generation adds
- WiFi 6 handles many devices at once better than WiFi 5, saves phone battery with Target Wake Time, and is now standard on budget routers.
- WiFi 6E adds the 6 GHz band: wide, quiet channels with no old devices, but shorter range through walls.
- WiFi 7 doubles channel width to 320 MHz on 6 GHz and adds MLO, which lets a device use several bands at once for speed and lower lag.
WiFi 6E is the generation I reach for when the neighbours crowd 5 GHz.
Which should you buy?
- Internet under 500 Mbps, mostly older devices: WiFi 6 is plenty.
- Apartment with many neighbors, newer phones and laptops: WiFi 6E avoids crowded 5 GHz.
- Gigabit or multi-gig fiber, latest devices, long-term buy: WiFi 7.
- Large home: coverage matters more than generation. Consider mesh.
For most homes I see, the answer is WiFi 6, and the money goes to coverage.
Things to watch
- Your device must support the same standard to benefit.
- 6 GHz needs line of sight more than 5 GHz.
- Advertised speeds add up all bands, real speeds are much lower.
- Check for a 2.5 Gbps WAN port if you have plans above 1 Gbps.
The WAN port is the detail I check first on a fast plan.
Do your devices support it?
A new router only brings new speeds to devices that support the same WiFi generation. Everything else connects at its own older speed.
- WiFi 6: most phones and laptops from 2020 onwards, including iPhone 11 and newer and most recent Android flagships.
- WiFi 6E: iPhone 15 Pro and newer, Pixel 6 and newer, Galaxy S21 Ultra and newer, and many 2022+ laptops.
- WiFi 7: flagship phones and laptops from 2024 onwards, such as iPhone 16 and Galaxy S24 series.
Check your phone or laptop’s spec page for 802.11ax (WiFi 6), 6 GHz support (6E) or 802.11be (WiFi 7) before deciding. The spec page is the check I do before I spend anything.
The 6 GHz band in plain words
WiFi 6E and WiFi 7 can use the 6 GHz band, which is like a brand-new motorway with almost no traffic. It’s fast and quiet, but it doesn’t reach as far through walls as 5 GHz. Think of it as the band for the room the router is in and maybe the one next door.
Availability depends on where you live, since not every country has opened the full 6 GHz band for WiFi. Check your local rules if you’re buying abroad. The room next door is where I expect 6 GHz to stop working well.
Cost vs benefit for a typical home
- Internet under 500 Mbps: a good WiFi 6 router or mesh covers it well.
- Gigabit plan, newer phones: WiFi 6E or entry WiFi 7 starts to make sense.
- Multi-gig fibre and new devices: WiFi 7 with 2.5 or 10 Gbps ports is worth it.
- Big home: better coverage (mesh) matters more than the newest standard.
Coverage is where I put the money first, every time.
Multi-Link Operation in WiFi 7
WiFi 7’s headline feature is Multi-Link Operation (MLO). A device can use two or three bands at once, combining their speed or switching instantly to the clearest one. It reduces lag spikes and helps in busy homes. Both the router and the device must support MLO, and early devices may support only some modes.
MLO is the feature I watch most in WiFi 7, and the one I wait to see in real devices.
