The three generations compared
The official names map to IEEE standards. Wi-Fi 6E is Wi-Fi 6 extended to the 6 GHz band.
| Feature | Wi-Fi 5 | Wi-Fi 6 / 6E | Wi-Fi 7 |
|---|---|---|---|
| Standard | 802.11ac | 802.11ax | 802.11be |
| Bands | 5 GHz (2.4 GHz via Wi-Fi 4) | 2.4 + 5 GHz (6E adds 6 GHz) | 2.4 + 5 + 6 GHz |
| Widest channel | 160 MHz | 160 MHz | 320 MHz (6 GHz) |
| Modulation | 256-QAM | 1024-QAM | 4096-QAM |
| Many-device efficiency | Downlink MU-MIMO | OFDMA, uplink + downlink MU-MIMO | OFDMA plus multi-resource units |
| Standout feature | Fast 5 GHz | Handles crowded networks; Target Wake Time saves battery | Multi-Link Operation (uses bands simultaneously) |
What Wi-Fi 6 improves
Wi-Fi 6's biggest gain isn't peak speed but efficiency. OFDMA lets the router serve several devices in one transmission instead of taking turns, which cuts latency when phones, TVs and smart devices are all active. Target Wake Time lets devices sleep between scheduled check-ins, which helps battery life.
In a busy home, that means steadier performance at peak times more than a higher number on a single speed test.
In short: Wi-Fi 6 is about serving many devices smoothly.
What Wi-Fi 6E and Wi-Fi 7 add
Wi-Fi 6E opens the 6 GHz band: lots of clean spectrum without older devices slowing it down, but with shorter range than 5 GHz. Its use depends on national regulations, so check that 6 GHz Wi-Fi is permitted and enabled where you live.
Wi-Fi 7 doubles channel width to 320 MHz on 6 GHz, packs more data per signal (4096-QAM) and adds Multi-Link Operation, where a device uses two bands at once for higher throughput and lower, steadier latency. These gains need a Wi-Fi 7 device close to the router.
Will upgrading make your internet faster?
Compare your plan speed with what you get over Wi-Fi. Run the speed test on a cable (or right next to the router) and then in the rooms you use. If the results near the router match your plan and only distant rooms are slow, the problem is coverage, which a mesh system or better placement fixes more cheaply than a new standard.
If you get much less than your plan even next to the router, or you have many devices and a plan above a few hundred Mbps, a newer router is likely to help.
| Your situation | Good choice |
|---|---|
| Plan up to ~100 Mbps, few devices | Wi-Fi 5 is enough; upgrade only if the router is old or unsupported |
| Busy home, 10+ devices, or 100–500 Mbps | Wi-Fi 6 |
| Large home or thick walls | Wi-Fi 6 mesh, ideally with wired backhaul |
| 1 Gbps+ plan, new devices | Wi-Fi 6E or Wi-Fi 7 |
How to check which Wi-Fi standard you're using
On Windows, run netsh wlan show interfaces and look at “Radio type” (802.11ac = Wi-Fi 5, 802.11ax = Wi-Fi 6). On a Mac, hold Option and click the Wi-Fi icon to see the PHY mode. On Android, the Wi-Fi details screen often shows a Wi-Fi 5/6 badge. The connection uses the best standard both the router and device support.
Common questions
Will a Wi-Fi 6 router make my internet faster?
Only if Wi-Fi was the bottleneck. If your plan is 20–50 Mbps and a Wi-Fi 5 router already delivers that in every room, a new router won't raise your speed test result. It helps most in homes with many devices or plans above a few hundred Mbps.
Do I need Wi-Fi 6 devices to benefit from a Wi-Fi 6 router?
Mostly yes. Older devices still connect, but use the older standard. A newer router can still help them indirectly through better range and by finishing other devices' transfers faster.
What are the maximum speeds like 5,400 Mbps on the box?
They add up the theoretical maximum of every band under ideal lab conditions. A single phone or laptop typically gets a fraction of that, limited by its own antennas and the distance from the router.
