WiFi 6, WiFi 6E and WiFi 7 are three generations of wireless networking, and each one solves a different problem. WiFi 6 (802.11ax) made networks more efficient when many devices are connected, WiFi 6E took that same technology into the new, uncrowded 6 GHz band, and WiFi 7 (802.11be) adds much wider channels and the ability to use several bands at once for higher speed and lower latency. Whether you need the newest one depends on your internet plan, your devices and the size of your home.
Key takeaways
- WiFi 6 is still a solid choice for most homes with internet plans up to roughly 500 Mbps–1 Gbps.
- WiFi 6E adds the 6 GHz band, which is far less congested, but has shorter range through walls.
- WiFi 7 brings 320 MHz channels, Multi-Link Operation and better latency, and is best paired with multi-gig internet or demanding local use.
- You only get the benefits of a new standard when both the router and your device support it.
- The "max speed" on the box is a theoretical total across all bands, not what a single phone or laptop will see.
WiFi 6, 6E and 7 at a glance
The table below summarizes the headline technical differences. Maximum data rates are theoretical figures from the specifications, combining all streams and bands; real devices see a fraction of them.
| Feature | WiFi 6 | WiFi 6E | WiFi 7 |
|---|---|---|---|
| IEEE standard | 802.11ax | 802.11ax (6 GHz) | 802.11be |
| Bands | 2.4 GHz, 5 GHz | 2.4, 5 and 6 GHz | 2.4, 5 and 6 GHz |
| Max channel width | 160 MHz | 160 MHz | 320 MHz (6 GHz only) |
| Highest modulation | 1024-QAM | 1024-QAM | 4096-QAM (4K-QAM) |
| Theoretical max rate | ~9.6 Gbps | ~9.6 Gbps | ~46 Gbps |
| Multi-Link Operation | No | No | Yes |
| Security | WPA3 for certification | WPA3 required on 6 GHz | WPA3 required on 6 GHz |
| Typical phone/laptop speed near router | Several hundred Mbps | Several hundred Mbps to ~1 Gbps+ | 1 Gbps+ with a capable device |
The last row is deliberately conservative. Actual throughput depends on how many antennas (spatial streams) your device has, distance, walls, interference and how busy the network is.
What WiFi 6 changed
WiFi 6 was less about raw speed and more about handling crowded networks. Before it, a router largely talked to one device at a time on a channel, which caused delays when a home had dozens of phones, TVs, speakers and cameras.
OFDMA and MU-MIMO
OFDMA (orthogonal frequency-division multiple access) lets the router split a channel into smaller slices and serve several devices in a single transmission. That is especially helpful for lots of small, frequent bits of traffic, such as smart home sensors, chat apps and game updates. WiFi 6 also expanded MU-MIMO so the router can send to and receive from multiple devices simultaneously.
Target Wake Time and BSS Coloring
Target Wake Time lets devices schedule when they wake up to talk to the router, which can improve battery life on phones and IoT gadgets. BSS Coloring tags traffic from your network so your router can more easily ignore overlapping signals from neighbors, a real benefit in apartments.
For many households, WiFi 6 is still enough. If your plan is a few hundred Mbps and your router is reasonably central, a quality WiFi 6 router will rarely be the bottleneck.
What WiFi 6E adds: the 6 GHz band
WiFi 6E uses the same 802.11ax technology as WiFi 6, but adds access to the 6 GHz band. In the US, regulators opened up to 1,200 MHz of spectrum there, more than the 2.4 GHz and 5 GHz bands combined. Many countries in Europe, along with the UK, currently allow a smaller lower portion of the band (around 500 MHz), which still adds plenty of room.
Why 6 GHz matters
The big win is clean spectrum. Only WiFi 6E and newer devices can use 6 GHz, so there are no older devices slowing things down, and far fewer neighboring networks competing for airtime. There is also enough room for multiple wide 160 MHz channels, which is how 6E devices reach high speeds without interference.
The trade-off: range
Higher frequencies lose strength faster, especially through walls, floors and furniture. The 6 GHz band typically covers less area than 5 GHz from the same router. In a small apartment that is fine and even helpful, since your neighbors' 6 GHz signals won't reach you either. In a large or multi-story house, you may need a mesh system or a wired access point to get 6 GHz in every room.

What WiFi 7 brings
WiFi 7 (802.11be) is the first major redesign since WiFi 6. The Wi-Fi Alliance began certifying WiFi 7 devices in early 2024, and support is now common in flagship phones, recent laptops and mid-range to premium routers.
320 MHz channels
WiFi 7 doubles the maximum channel width to 320 MHz, but only in the 6 GHz band. A wider channel is like a wider highway: more data can flow at once. In the US there is room for several 320 MHz channels; in regions with only the lower part of the 6 GHz band, there is room for about one, so the benefit depends on where you live.
4K-QAM
4096-QAM packs 12 bits into each symbol, compared with 10 bits for WiFi 6's 1024-QAM. That is roughly a 20% boost in peak data rate, but it only works with a very strong, clean signal, which usually means the device is close to the router.
Multi-Link Operation (MLO)
MLO is the most practical WiFi 7 feature. A device can connect over two or more bands at once, for example 5 GHz and 6 GHz, and either combine them for more throughput or switch traffic instantly to the less congested link. The result can be steadier performance and lower, more consistent latency, which matters for video calls, cloud gaming and VR. If latency is your main concern, our explainer on what a good ping for gaming is covers what numbers to aim for.
Preamble puncturing
WiFi 7 can also "punch out" a small portion of a wide channel that has interference and keep using the rest. Older standards would have to fall back to a narrower channel entirely.
How fast will WiFi actually be in your home?
Box numbers like "AX5400" or "BE19000" add up the theoretical maximum of every band on the router. A single device uses only one band (or a couple with MLO) and usually two spatial streams, so it sees far less.
As a rough guide, a modern two-stream phone or laptop close to a good router might see:
- WiFi 6 on 5 GHz (80–160 MHz): often 500–900 Mbps at short range.
- WiFi 6E on 6 GHz (160 MHz): similar or a bit higher, with more consistency in busy areas.
- WiFi 7 on 6 GHz (320 MHz): potentially well above 1 Gbps at short range.
Move a couple of rooms away and every one of these drops considerably. The best way to know what you are getting is to measure. Run a free speed test next to the router and then in the rooms where you use devices most, or use our WiFi speed test to compare spots around the house.
Remember that WiFi is only one link in the chain. If your internet plan is 300 Mbps, no router can push internet downloads past roughly 300 Mbps. A newer standard can still help by keeping that speed steady in more places and under more load.
Which WiFi standard should you choose?
Stick with WiFi 6 if
- Your internet plan is under about 500 Mbps.
- You live in a small or medium home and most devices are a few years old.
- You want a good router at a low price.
Choose WiFi 6E if
- You live in an apartment or dense area with many competing networks.
- Your phone, laptop or tablet already supports 6 GHz.
- You can find a 6E router at a good price as WiFi 7 models push older stock down.
Choose WiFi 7 if
- You have a multi-gig plan (for example 2 Gbps or more) and want to use it wirelessly.
- You do a lot of large local file transfers, VR or cloud gaming.
- You are buying a mesh system that will last many years; WiFi 7 mesh systems can use MLO and a 6 GHz backhaul between units.
- Your newest devices support WiFi 7.
How to check what your devices support
Before upgrading, check which standard your current devices use. On Windows, open Command Prompt and run netsh wlan show interfaces; the "Radio type" line shows 802.11ax for WiFi 6/6E or 802.11be for WiFi 7, and the "Band" line shows 2.4, 5 or 6 GHz. On a Mac, hold the Option key and click the WiFi icon in the menu bar to see the PHY mode (such as 802.11ax) and the channel and band.
On phones, check the manufacturer's specification page for "Wi-Fi 6E" or "Wi-Fi 7". If most of your gadgets are WiFi 5 or WiFi 6, a WiFi 7 router will still work well, but they won't use its headline features.
Bottom line
WiFi 6 made home networks efficient, WiFi 6E gave them clean spectrum in the 6 GHz band, and WiFi 7 adds wider channels and Multi-Link Operation for higher speeds and steadier latency. For most homes with sub-gigabit internet, a good WiFi 6 or 6E router is still more than capable; WiFi 7 is worth it if you have multi-gig service, new devices and the budget.
Whatever you choose, measure before and after. Test your connection speed near the router and in a far room, and compare the results with your plan using our guide to what a good internet speed is.
