Modern users rarely think about what exactly is happening in the air when they connect to a home network, but encountering new symbols on a smartphone screen or in a router's specifications inevitably raises questions. While previously we only saw the numbers 2.4 and 5, now the operating system interface may prompt a connection to the network with a mysterious addition or symbol that was not previously encountered. Understanding What is Wi-Fi 6?, becomes critically important when choosing new equipment, as marketing names often conceal complex technical standards.
Visual identification of the standard 802.11ax (the technical name of the technology) is implemented in far from uniform ways on end-user devices. While router manufacturers have long since incorporated new logos into their web interfaces, mobile operating systems like Android and iOS are implementing these changes gradually and selectively. The key point is that even if your router supports 6G, your phone may display a regular Wi-Fi icon if it is not itself certified to work with the new protocol.
In this article, we'll take a detailed look at all possible markings, from official Wi-Fi Alliance logos to hidden indicators in Android settings. You'll learn to distinguish a genuine high-speed standard from marketing gimmicks and understand why test speeds may not meet expectations despite a "six" in the specifications.
Official Wi-Fi Alliance nomenclature
The Wi-Fi Alliance, which certifies wireless equipment, has decided to simplify the confusing IEEE standards naming system. Complex alphanumeric codes like 802.11ac or 802.11n have been replaced with simple generation numbers. Wi-Fi 6 — is the commercial name for the 802.11ax standard, which is intended to make life easier for the average consumer when choosing a router or smartphone.
The official Wi-Fi logo is a "6" with a "6" in the lower right corner. This symbol indicates support for OFDMA (Orthogonal Frequency-Division Multiple Access) technology, which allows for efficient distribution of network resources among multiple devices. However, just because the logo appears on the router's box doesn't guarantee you'll see it on your device's screen.
⚠️ Please note: Equipment manufacturers are not required to use a uniform graphic style. You may see the "Wi-Fi 6 CERTIFIED" logo on the router box, but it may appear differently or not at all in the setup interface or on your smartphone screen.
It's important to understand the difference between frequency band and standard generation. Many users mistakenly believe that operating in the 5 GHz band automatically means using Wi-Fi 6. This is not true: the fifth generation (Wi-Fi 5 or 802.11ac) also operated primarily at 5 GHz, but lacked the key efficiency improvements inherent in the new standard.
How is the standard displayed on Android smartphones?
In the world of mobile operating systems, the situation with the indication of new standards is mixed. Google began implementing support for visual display of sixth-generation Wi-Fi starting with Android 10, but even then it doesn't work on all devices. If your smartphone supports 802.11ax and connected to the corresponding router, a small number "6" may appear in the status bar next to the signal icon.
However, the absence of a number doesn't always mean the connection is using the old protocol. Some UI manufacturers, such as Samsung, Xiaomi, or Huawei, may hide this indicator for the sake of a cleaner interface or simply haven't implemented it in their Android versions. In such cases, the only way to confirm the connection type is to thoroughly analyze the settings.
To check the actual connection status, go to the settings menu. The path may vary, but it usually looks like this: Settings → Connections → Wi-Fi → (Your network name) → More detailsIn the window that opens, look for the line "Protocol" or "Standard." It will indicate the current connection, for example, 802.11ax or 802.11ac.
- 📱 The number "6" next to the icon directly indicates the active Wi-Fi 6 standard.
- 🔍 The lack of a number is not a reason to panic; it may be a feature of the interface.
- ⚙️ Checking in the "About phone" or "Network status" menu gives a 100% guarantee.
- 📉 If the speed is slow, your device may have entered compatibility mode.
Indication in router interfaces and access point
Modern routers that support the new standard often have their own network activity indicators. The web interfaces of devices from ASUS, TP-Link, Keenetic, and other manufacturers typically contain detailed technical information. In the "Network Map" or "Client List" sections, you can see the protocol used by each connected device.
Manufacturers often use color coding or special icons in the list of connected clients. For example, devices running on Wi-Fi 6, may be marked with a "6" icon or highlighted in a different color than clients running older standards. This allows for a quick assessment of the effectiveness of the network upgrade.
Some router models have a physical button or software switch for activating "Wi-Fi 6 Only" mode. Enabling this feature will prevent older devices from connecting to the network. This is a useful diagnostic tool, but it's best left untouched for everyday use, to avoid disrupting internet access for guest devices.
| Wi-Fi generation | IEEE standard | Year of release | Max. speed (theoret.) |
|---|---|---|---|
| Wi-Fi 4 | 802.11n | 2009 | 600 Mbps |
| Wi-Fi 5 | 802.11ac | 2014 | 3.5 Gbps |
| Wi-Fi 6 | 802.11ax | 2019 | 9.6 Gbps |
| Wi-Fi 6E | 802.11ax (6 GHz) | 2020 | 9.6 Gbps |
Technical differences: 802.11ax vs. 802.11ac
The main technical difference behind the Wi-Fi 6 label is the transition to a more efficient modulation and multiple access method. If Wi-Fi 5 While 802.11ac only used MU-MIMO technology for the downlink (from the router to the device), the new standard supports this feature in both directions. This is critical for the stability of video calls and online gaming.
Another fundamental change is the introduction of OFDMA. This technology allows a single communication channel to be divided into multiple smaller subchannels, transmitting data to different devices simultaneously within a single time slot. In an apartment building, where the airwaves are clogged with neighboring signals, this provides a noticeable performance boost, even if the speed indicator remains unchanged.
Also worth mentioning is the Target Wake Time (TWT) feature, which allows devices to negotiate with the router when to wake up to transmit data. This significantly saves battery life for smartphones and IoT devices, which is especially important for smart homes.
What is BSS Coloring?
BSS Coloring is a technology that adds a color tag to your network's data packets. The router ignores signals from neighboring networks with different colors, reducing interference in densely populated areas.
Compatibility issues and feedback
One of the key features of the 802.11ax standard is full backward compatibility. This means a Wi-Fi 6 router will work perfectly with smartphones from ten years ago. However, this also poses a potential problem: if even one older device (a Wi-Fi 4 client) is added to the network, the router may be forced to employ protection mechanisms that reduce overall network performance for everyone.
Users often don't notice a difference in speed because their provider's plan is limited to, say, 100 Mbps. In this case, even an older Wi-Fi 4 system can deliver the full speed available, and upgrading to Wi-Fi 6 won't yield any improvement in benchmark results, although ping and stability may improve.
⚠️ Note: To achieve maximum speed, both the router and the client device (smartphone, laptop) must support the 802.11ax standard. If one link in the chain is older, the connection will be established using a lower common standard.
Furthermore, there are regional restrictions. In some countries, the use of certain frequency channels or the 160 MHz channel width may be restricted by law. A router purchased in one country may not reach its full potential in another due to software limitations in regional settings.
How to check your actual speed and connection type
To ensure you're truly taking advantage of the new standard, simply looking at the icon isn't enough. It's best to conduct a hands-on test. There are specialized Android apps, such as "Wi-Fi Man" from Ubiquiti or "WiFi Analyzer," that display detailed technical information about your current connection, including channel width and standard.
In Windows, you can check via the command line. Open the terminal and enter the command netsh wlan show interfacesIn the list that appears, find the line "Radio type". If it says 802.11ax, then you are connected via Wi-Fi 6. If 802.11ac or 802.11n is indicated, then the connection is using the older protocol.
netsh wlan show interfacesWhen conducting speed tests, it's important to keep in mind that actual performance is always lower than theoretical values due to protocol overhead, interference, and distance to the router. For Wi-Fi 6, speeds of around 600-800 Mbps on a single stream in close proximity to the access point are considered normal.

Frequently Asked Questions (FAQ)
Will Wi-Fi 6 work if the router has old firmware?
Most likely, no, or it will be unstable. Activating 802.11ax features often requires updating your router's firmware to the latest version, as support for the new standard is added through software even to devices with the appropriate hardware.
Does Wi-Fi 6 affect health due to its higher frequency?
No, the Wi-Fi 6 standard operates in the same frequency bands (2.4 and 5 GHz) as previous generations. Claims of harmful radiation have no scientific basis for the consumer use of Wi-Fi equipment.
Do I need to change my ISP cable to use Wi-Fi 6?
Wi-Fi 6 itself doesn't require a cable upgrade, as it's a wireless technology. However, if your data plan exceeds 100 Mbps, make sure your ISP cable and router port support speeds of 1 Gbps or higher (the cable should be at least Cat5e, preferably Cat6).
Why doesn't the phone show the number 6, even though the router is new?
It's possible your smartphone simply doesn't support this standard. The number may also not be displayed due to operating system interface settings or because the phone is connected to the 2.4 GHz band, where the advantages of sixth generation are less noticeable.
