The modern internet demands that gadgets not only have an antenna, but also the ability to process huge data streams without lag. This is why wireless broadband is becoming the de facto standard in new devices. Wi-Fi 6, also known as 802.11ax. Many users still don't know which phones support this protocol, missing out on the opportunity to significantly improve connection stability in dense urban environments.
The transition to a new standard is not just a marketing ploy, but a real necessity for those who use a smart home or frequently download large files on the fly. Wi-Fi 6 Provides better performance in high-traffic networks with multiple devices connected simultaneously. If your router has already been updated to AX, but your phone is still running slowly, the problem may be due to the lack of support for the new standard on your smartphone.
In this article, we'll dive into the technical details, help you test your device, and compile an up-to-date list of models ready for high speeds. You don't need to be an engineer to understand the differences between wireless generations. We've prepared detailed tables and instructions to help you make an informed decision about buying a new gadget or setting up your current network.
Technological differences between Wi-Fi 6 and previous generations
The main advantage of the new standard is the use of technology OFDMA (Orthogonal Frequency-Division Multiple Access). Unlike previous versions, where the router transmitted data to each device in small packets one at a time, OFDMA allows data for multiple devices to be combined into a single packet. This significantly reduces latency and increases overall network throughput, which is especially noticeable when using instant messaging and video calls.
Another important innovation was the technology TWT (Target Wake Time), which optimizes power consumption. The smartphone can now negotiate with the router when to wake up to transfer data, spending the rest of the time in deep sleep. This significantly saves battery life, which is critical for modern slim smartphones with capacious screens.
⚠️ Please note: For all Wi-Fi 6 features to work, both the router and the receiving device (phone, laptop) must support this standard. If either device only supports Wi-Fi 5, the connection will be established using the older protocol.
Also worth mentioning is modulation 1024-QAM, which allows more data to be encoded in a single signal. This provides a speed increase of approximately 25% compared to the previous 256-QAM standard. However, realizing this benefit requires not only a compatible phone but also a high-quality signal without significant interference.
Why doesn't the speed always increase?
Internet speed is limited not only by your phone's Wi-Fi module but also by your provider's plan. Even if your phone supports 2 Gbps but your plan is capped at 100 Mbps, you won't be able to go higher. Wi-Fi 6 primarily improves stability and multitasking.
Apple iPhones with Wi-Fi 6 support
Apple has started implementing the 802.11ax standard in its devices, starting with the series iPhone 11This was made possible by the installation of Broadcom chips, which ensure compatibility with new frequencies and signal encoding methods. Since then, all flagship and many mid-range models from the Cupertino company have been equipped with advanced communication modules.
Owners of older models such as iPhone X or iPhone 8Unfortunately, these devices are limited to the Wi-Fi 5 (802.11ac) standard. While this is still sufficient for casual browsing, the difference will be noticeable when watching 4K video from a NAS or using AR apps. New iPhone models take advantage of this standard to quickly upload photos to iCloud and sync data.
- 📱 iPhone 11 / 11 Pro / 11 Pro Max — the first models to support the new standard.
- 📱 iPhone 12/13/14/15 series - full support for all functions, including improved operation in the 5 GHz range.
- 📱 iPhone SE (2nd and 3rd generation) — a budget entry into the world of fast networks.
- 📱 iPad Pro and iPad Air — the tablets also received an update to their Wi-Fi modules.
It's worth noting that Apple is also introducing support for the 6 GHz band (Wi-Fi 6E) in its latest models, but basic Wi-Fi 6 operates on 2.4 and 5 GHz frequencies, which is relevant for most home routers. You can check your iPhone's Wi-Fi version in the specifications on the official website, as this information is usually not displayed in the phone's settings.
Flagships and budget Android phones: who's on the list?
The Android market is more diverse, as many manufacturers use different chipsets. The first to support Wi-Fi 6 received flagships based on processors Snapdragon 865 and newer, as well as top solutions from Exynos And DimensityThis means that most phones released after 2020 in the "upper mid-range" segment are already equipped with the necessary module.
However, in the budget segment, manufacturers often save money by installing older Wi-Fi 5 modules. Therefore, when buying an inexpensive smartphone, even in 2026, you should carefully study the specifications. The presence of a 5G modem in a phone often (but not always) correlates with the presence of a modern Wi-Fi module, as both components are part of a single telecommunications platform.
| Brand | Wi-Fi 6 Series | Examples of models |
|---|---|---|
| Samsung | Galaxy S20 and later, Galaxy Note 20, Galaxy Z Fold/Flip | S20, S21, S22, S23, S24, Note 20 Ultra |
| Xiaomi | Mi 10 and newer, most Redmi Note series models (Pro/Pro+) | Mi 11, Xiaomi 12/13/14, Redmi Note 10 Pro+ |
| OnePlus | OnePlus 8 and newer | OnePlus 8T, 9, 10, 11, Nord 2 (not all) |
| Pixel 5 and later | Pixel 6, 7, 8, 8 Pro | |
| Huawei | P40 and up, Mate 40 and up | P50, Mate 50, Nova 9 |
It's important to understand that the list of models is constantly expanding. If you're choosing a mid-range phone, look for a reference to the standard in the specifications. 802.11axThe absence of this abbreviation means the device will only operate at the speed of the previous generation, which could become a bottleneck if you have a gigabit home internet connection.
How to check if your phone supports Wi-Fi 6
The most reliable way to find out your device's capabilities is to check the official specifications on the manufacturer's website. However, if you already have the phone, you can use software methods. There are many network diagnostic apps for Android that display detailed connection information.
One of the most popular tools is the application WiFi Man from Ubiquiti or Fritz!App WLANOnce installed and launched, these utilities display not only the current speed, but also the connection standard, channel frequency, and signal strength. If you see 802.11ax or Wi-Fi 6, then your phone is fully compatible.
For users who prefer system methods, you can try searching for information in hidden menus, although this does not work on all firmware versions. Often in the section Settings → About phone → All specs (or similar) you can find a line describing the wireless modules. Another indirect indicator is the presence of an option in the Wi-Fi settings to select a frequency of 5 GHz, although this does not guarantee support for 6G.
⚠️ Note: Android menu interfaces vary depending on the operating system (MIUI, OneUI, ColorOS). If you can't find the information in the settings, use third-party diagnostic apps from Google Play.
☑️ Check for Wi-Fi 6 support
Do I need a special router to use Wi-Fi 6?
Yes, the presence of a phone with support 802.11ax — that's only half the equation. The second essential component is a router, which must also support this standard. If your router is several years old and only supports Wi-Fi 5 (ac), your phone will automatically switch to that mode, and you won't benefit from the new technology.
When choosing a router, pay attention to the markings AX in the model name (e.g., AX1800, AX3000, AX6000). The number after AX indicates the combined theoretical speed in both ranges. For home use with a plan of up to 500 Mbps, the entry-level AX1800 models are quite sufficient. However, if you have a gigabit connection and many devices, you should consider more powerful solutions.
It's also worth considering that Wi-Fi 6 routers often feature more powerful processors, which improves the stability of even older devices on the network. They handle queues of requests better when one user is watching 4K video or another is playing online games. This makes upgrading your router useful even if not all the phones in the house are new.
The impact of the standard on the speed and stability of the connection
Users often wonder whether they'll notice a difference in everyday use. If you live in a private home or apartment where no one but your family uses Wi-Fi, the speed boost may not be noticeable during casual surfing. However, in apartment buildings, where the airwaves are clogged with dozens of neighboring networks, Wi-Fi 6 works wonders.
Thanks to improved interference management and more efficient spectrum use, gaming ping becomes more stable, and video calls stop dropping during peak hours. Large files download faster, especially if your provider offers speeds above 300-400 Mbps. In Speedtest tests, the difference between Wi-Fi 5 and Wi-Fi 6 at short ranges can reach 30-40%.
Furthermore, the new standard performs better at the limits of the signal's range. Where an older phone would have lost service or throttled its speed to a crawl, a Wi-Fi 6 device can maintain a stable, albeit slower, connection. This is especially important for large apartments and offices, where the router is in one room and the user in another.
Does Wi-Fi 6 affect battery life?
Paradoxically, Wi-Fi 6 can save battery life thanks to TWT technology. The device doesn't need to keep the radio module constantly active and in active standby; it "wakes up" only at strictly designated times by the router to transfer data. However, on very old routers, a new phone may perform less efficiently due to the constant attempts to switch modes.
Does Wi-Fi 6 work on 2.4GHz?
Yes, the 802.11ax standard operates in both the 2.4 GHz and 5 GHz bands. However, the primary benefits of high speed and low latency are realized in the 5 GHz band. At 2.4 GHz, the gains will be less noticeable due to the noise in that band, but connection stability will still improve.
Do I need to change my SIM card for Wi-Fi 6 to work?
No, Wi-Fi 6 is a local wireless network technology that has nothing to do with cellular carriers or SIM cards. Your SIM card can be any size, even a very old one, and it won't affect your home Wi-Fi speed. The only important factors are having the appropriate router and internet plan.
Will a phone with Wi-Fi 6 work on an old router?
Yes, Wi-Fi standards are backward compatible. Your new Wi-Fi 6 phone will connect seamlessly to an older Wi-Fi 4 (n) or Wi-Fi 5 (ac) router. The connection will be established using the highest standard available for both devices; you just won't be able to take advantage of the new generation's speeds.
What is Wi-Fi 6E and do you need it?
Wi-Fi 6E is an expanded version of the standard, adding a third 6 GHz frequency band. This provides even more clear channels and reduces interference. However, it requires both a router and a phone that supports 6E. Currently, this is only relevant for high-end flagships and heavily loaded networks; under normal conditions, standard Wi-Fi 6 is sufficient.
