Router boxes are covered in names like WiFi 6, WiFi 6E and WiFi 7, along with huge speed numbers that no home ever reaches. So what’s actually different, and which one should you buy? This guide explains each standard in plain English and helps you decide whether an upgrade is worth it.
The quick answer
- WiFi 6 is enough for most homes with an internet plan up to about 500 Mbps.
- WiFi 6E adds the 6 GHz band – a big improvement in crowded apartment buildings, if your devices support it.
- WiFi 7 is the best choice for gigabit and multi-gig plans, homes with many new devices, and anyone buying a router to keep for many years.
WiFi generations at a glance
| WiFi 6 | WiFi 6E | WiFi 7 | |
|---|---|---|---|
| Technical name | 802.11ax | 802.11ax (6 GHz) | 802.11be |
| Introduced | 2019 | 2021 | 2024 |
| Frequency bands | 2.4 GHz + 5 GHz | 2.4 + 5 + 6 GHz | 2.4 + 5 + 6 GHz |
| Maximum channel width | 160 MHz | 160 MHz | 320 MHz (6 GHz) |
| Theoretical max speed | about 9.6 Gbps | about 9.6 Gbps | about 46 Gbps |
| Key new feature | OFDMA, better efficiency with many devices | Access to the uncrowded 6 GHz band | Multi-Link Operation (MLO), 4K-QAM |
The “theoretical max” is a lab number shared across all devices and antennas. In a real home, a single phone or laptop typically gets a fraction of it. What matters is how well the router handles your devices, your walls and your neighbors’ networks.
WiFi 6: efficiency for busy homes
WiFi 6 wasn’t mainly about raw speed. Its biggest improvements help when many devices are connected at once:
- OFDMA lets the router serve several devices in a single transmission instead of making them wait in line.
- Improved MU-MIMO sends data to multiple devices simultaneously.
- Target Wake Time helps phones and smart-home devices save battery.
For a typical home with a plan up to a few hundred Mbps, a good WiFi 6 router still performs very well.
WiFi 6E: the 6 GHz band
WiFi 6E uses the same technology as WiFi 6 but adds a brand-new frequency band: 6 GHz. Older devices can’t use it, so it’s free from the congestion of 2.4 GHz and 5 GHz. In apartment buildings where dozens of networks overlap, that can make a dramatic difference in speed and stability.
The trade-off is range: 6 GHz signals don’t pass through walls as well as 5 GHz. It’s excellent in the same room or the next room, but you may need a mesh system to cover a large home on 6 GHz. Note that the amount of 6 GHz spectrum available varies by country.
WiFi 7: built for multi-gig
WiFi 7 brings several upgrades at once:
- 320 MHz channels on the 6 GHz band – double the width of WiFi 6E, for much higher top speeds close to the router.
- Multi-Link Operation (MLO) lets a device use several bands at the same time or switch between them instantly, improving speed and reducing lag and dropouts.
- 4K-QAM packs more data into each transmission when the signal is strong.
To benefit fully, you need WiFi 7 devices as well. Many flagship phones and laptops released from 2024 onward support it, and the list is growing quickly.
Do you need to upgrade?
| Your situation | Recommendation |
|---|---|
| Internet plan under 300 Mbps, few devices | WiFi 6 is plenty |
| Crowded apartment building, newer devices | WiFi 6E or WiFi 7 for the 6 GHz band |
| Gigabit or multi-gig plan | WiFi 7, ideally with a multi-gig Ethernet port |
| Large home | A mesh system (WiFi 6 or newer) matters more than the standard |
| Router older than WiFi 5 (802.11ac) | Upgrade – almost any modern router will be a big step up |

Check your devices first
A new router can only talk to each device using the best standard both support. If your laptop only has WiFi 5, it will connect to a WiFi 7 router using WiFi 5. Check the specifications of your most-used devices:
- Windows: open Settings → Network & Internet → WiFi → your network’s properties and look at “Protocol”.
- Mac: hold Option and click the WiFi icon in the menu bar; the “PHY Mode” shows the standard in use.
- Phones: check the manufacturer’s specification page for “WiFi 6E” or “WiFi 7”.
Router upgrade tips
- If your plan is faster than 1 Gbps, choose a router with a 2.5 Gbps or faster WAN port – otherwise the port becomes the bottleneck.
- Prefer tri-band models if you’ll add mesh nodes later.
- Look for regular firmware updates and WPA3 security support.
- Place the new router centrally – a great router in the wrong spot still performs poorly. See our tips to boost your WiFi signal.
Frequently asked questions
Is WiFi 7 backward compatible?
Yes. WiFi 7 routers work with all older WiFi devices; those devices simply connect using their own, older standard.
Will WiFi 7 make my internet faster?
Only up to the speed of your internet plan. If your WiFi was the bottleneck – for example on a gigabit plan – you’ll see a big improvement. If your plan is 100 Mbps, a WiFi 7 router won’t make the plan itself faster, though it can improve coverage and stability.
Is WiFi 6E worth it over WiFi 6?
It is worth it if you live in a crowded area and your devices support 6 GHz. In a detached house with few neighboring networks, the difference is smaller.
Does WiFi 7 reduce ping for gaming?
Multi-Link Operation can reduce latency spikes and make WiFi more stable, which helps gaming. For the lowest possible ping, a wired Ethernet connection is still best – check yours with our ping test.
