Smartphone, tablet, and laptop users often notice a small change in the status bar: a small number 6 appears next to the standard wireless network icon. This isn't a random interface glitch or a software error, but rather the result of new communication standards that have become increasingly common in devices released in recent years. The appearance of this symbol indicates that your device is connected to the next generation network, which provides higher data transfer rates and lower latency compared to previous versions of the protocol.
Many gadget owners become concerned when they see strange changes in the interface, believing that this could indicate a traffic leak or a virus attack. However, we hasten to reassure you: the number indicates only the device being used. frequency range and communication standard, namely Wi-Fi 6 (also known as 802.11ax). This modern protocol is designed to replace the outdated Wi-Fi 5 (802.11ac) and ensure stable operation in high-density environments, which is especially important for apartment buildings and office centers.
In this article, we'll take a detailed look at the technical features of the standard, explain why digital data can appear and disappear, and provide step-by-step instructions for those who want to forcefully switch to an older, but compatible, operating mode. Understanding these processes will help you optimize your home network and eliminate possible problems with connecting old gadgets.
The 802.11ax technology standard and its advantages
The number 6 in the standard's name indicates the sixth generation of wireless technology, which replaces the fifth generation (Wi-Fi 5). The main difference is the use of more efficient data encoding methods and the ability to simultaneously handle multiple clients without sacrificing speed. While previously a router could choke when connecting a dozen smartphones, the new standard distributes resources more intelligently, using OFDMA technology.
It's important to understand that this mode requires support from both devices: the router and the receiving device. If your router only supports the older standard, the number 6 won't appear on your smartphone's screen, even if the phone itself is a flagship model. This is why the indicator often appears as a surprise after purchasing a new router or updating the firmware of existing equipment.
The key advantage is not only the maximum speed, which in theory can reach 9.6 Gbps, but also energy efficiency. The Target Wake Time (TWT) function allows devices iPhone or Android Negotiate with the router when to turn on the Wi-Fi module to receive data, which significantly saves battery life. This is especially important for wearables and IoT devices that need to operate autonomously for years.
⚠️ Attention: Actual connection speed always depends on your provider's plan, cable quality, airtime congestion from neighbors, and physical obstacles (such as walls) in the room. A 6 on the screen doesn't guarantee instant downloads of large files if your bandwidth is limited.
Furthermore, the new standard performs better in the 2.4 GHz band, traditionally considered slow and noisy. Thanks to improved modulation (1024-QAM), the throughput of this band has increased by approximately 37%, allowing older devices that don't support 5 GHz to operate more reliably and quickly.
Why does the 6 icon appear on iPhone and Android?
The number 6 appearing on your smartphone's screen is the operating system's default response to a handshake with the access point. When you approach the router, the devices exchange information about their capabilities. If both devices support the 802.11ax standard, iOS or Android displays a corresponding indicator to let the user know the connection is established. in the highest possible mode.
On Apple devices (iPhone, iPad), this indicator appeared with the release of iOS 14 and is supported starting with the iPhone 11. Owners of older models, such as the iPhone X or iPhone 8, will never see the number 6, even if connected to the most modern router, as their Wi-Fi modules are physically limited to the Wi-Fi 5 (802.11ac) standard. On Android smartphones, the situation is similar: the indicator appears on flagship and mid-range models released after 2019-2020.
Sometimes users notice the number 6 appearing and then disappearing. This may be due to the router dynamically switching clients between the 2.4 GHz and 5 GHz bands, or the device has moved to a distance where the signal of the new standard becomes unstable. In such cases, the smartphone automatically switches to a more reliable, albeit slower, protocol, and the number 6 disappears from the screen.
It's also worth noting the role of software. Even if the phone's hardware supports the new standard, the number may not be displayed on older versions of the operating system. Update to the latest version iOS or Android often adds this visual indication, making the interface more informative.
Differences between Wi-Fi 5, Wi-Fi 6 and Wi-Fi 6E
To better understand what's happening in your network, it's important to clearly distinguish between the different generations of standards. Confusion often arises from similar names and marketing ploys. Wi-Fi 5 (802.11ac) operates exclusively in the 5 GHz band, while Wi-Fi 6 (802.11ax) is universal and operates in both 2.4 GHz and 5 GHz.
The Wi-Fi 6E standard deserves special attention. The "E" stands for "Extended." The main difference is the introduction of a new, clear 6 GHz frequency band. This band offers virtually no interference from neighboring routers, microwave ovens, and Bluetooth devices, ensuring perfect stability. However, 6E requires a dedicated router and a client device that supports this band.
Below is a comparison table to help you organize your knowledge about the different generations of wireless communications and their characteristics:
| Characteristic | Wi-Fi 5 (802.11ac) | Wi-Fi 6 (802.11ax) | Wi-Fi 6E |
|---|---|---|---|
| Year of implementation | 2014 | 2019 | 2021 |
| Frequency ranges | 5 GHz | 2.4 GHz and 5 GHz | 2.4, 5 and 6 GHz |
| Maximum speed | up to 3.5 Gbps | up to 9.6 Gbps | up to 9.6 Gbps |
| MIMO technology | MU-MIMO (download only) | MU-MIMO (up/down) | MU-MIMO (up/down) |
| Energy efficiency | Standard | High (TWT) | High (TWT) |
The transition to new standards is an evolutionary process. If you have many smart devices at home (lamps, outlets, cameras) that put a strain on your network, upgrading to Wi-Fi 6 will be a noticeable improvement. However, for simple video viewing on a single tablet, the difference between fifth and sixth generations may not be so obvious.
How to disable the number 6 on iPhone
While the number 6 is a sign of a good connection, some users find it visually annoying or want to force the device to switch to a more compatible mode. In the operating system iOS Starting with version 14, the "Private Wi-Fi Address" feature was introduced, which often affects the display of network status and the behavior of the device in new protocols.
To change the settings, you need to go to the settings of a specific connection. Open Settings, select the item Wi-Fi and click on the blue information icon (i) next to your network name. In the menu that opens, find the switch Private Wi-Fi addressDisabling it may require re-entering the password and reconnecting.
However, if your goal is to specifically remove the number 6, disabling "Private Address" isn't always helpful, as the number indicates the physical connection standard. To ensure your iPhone forgets about Wi-Fi 6, you need to change the router settings, switching it to Legacy Mode or separating the 2.4 GHz and 5 GHz frequencies into different SSIDs. Then connect to a 2.4 GHz network, where Wi-Fi 6 operates differently or isn't as clearly visible.
⚠️ Attention: Disabling modern security features, such as MAC address randomization, can make your device more visible on other networks. Only do this on a trusted home network.
There's also the option to reset the network settings, which can sometimes help if the number 6 is stuck due to a software glitch. To do this, go to Settings → General → Transfer or reset iPhone → Reset → Reset Network SettingsThis action won't delete your photos or apps, but you'll have to re-enter saved Wi-Fi passwords.
Setting up a Private Address on Android devices
In the ecosystem Android The situation is similar, but the settings menu may differ depending on the manufacturer's operating system (Samsung One UI, Xiaomi MIUI, stock Android). The random MAC address feature also plays a key role in identifying the device on the next-generation network.
To find these settings, go to Settings → Connections (or Network & Internet) → Wi-FiClick on the gear icon or the name of the network you are connected to. Find the option IP parameters or PrivacyHere you'll see a choice between "Use the device's MAC address" and "Use a random MAC address." Switching to use the device's real MAC address sometimes changes how it communicates with the router.
Some users try using third-party apps to "boost the signal" or change the Wi-Fi region to affect the display of the number. This is not recommended, as such apps often require root access and can disrupt the stability of the communication module. It's better to use the built-in system tools.
If the number 6 is visually distracting, the only surefire way to remove it without losing speed is to disable Wi-Fi 6 support in the router's settings. This is usually done in the Wireless Settings or Wi-Fi Settings, where you need to uncheck 802.11ax or select a mode 802.11ac/n mixed.
Possible problems and their solutions
Despite the benefits, upgrading to the new standard can be challenging. The most common issue is a "connection loop," where a device repeatedly connects and disconnects from the network. This often occurs when a router attempts to use Wi-Fi 6 features, but the signal is too weak to support stable operation.
Another common issue is the incompatibility of older IoT devices (smart lightbulbs, robot vacuum cleaners) with new routers running in "Wi-Fi 6 only" mode. In this case, the devices simply don't see the network. The solution is to enable compatibility mode or create a guest network using the older standard.
It's also worth mentioning the issue with VPN services. Some encryption protocols can conflict with the new traffic management methods in Wi-Fi 6, causing a drop in speed. If you notice that your internet is slower with Wi-Fi 6, try temporarily disabling your VPN or changing the protocol in the app.
In rare cases, the number 6 may be displayed incorrectly due to a bug in the phone's firmware. If your internet speed is also low, it's a good idea to check for system updates. Manufacturers regularly release patches to fix wireless drivers.
⚠️ Attention: Router and smartphone settings interfaces are constantly being updated. The layout of menu items may differ from that described in the instructions. Always refer to the latest manuals for your specific device model.
Frequently Asked Questions (FAQ)
Does the number 6 affect battery consumption?
In contrast, the Wi-Fi 6 standard is designed with power saving in mind. The TWT feature allows the device to sleep for longer periods, waking up only to transmit data. However, if the signal is weak and the phone constantly tries to maintain a high-speed connection, power consumption may temporarily increase.
Do I need to change my router if my phone doesn't have the number 6?
No, you don't need to. The absence of the number 6 means your phone is connected to Wi-Fi 5 or 4. This doesn't mean your internet is poor. You should only replace your router if you're experiencing slow speeds or have a lot of connected devices.
Could the number 6 mean connecting to someone else's Wi-Fi?
No, the number only indicates the connection standard, not the signal source. You are connected to the network whose name is shown in the status bar. You can check the network name in the same Wi-Fi settings.
Why is there a number 6 on one phone and not on the other?
This depends on the phone model. The number will only appear if the phone's Wi-Fi module supports the 802.11ax standard. Older models are physically unable to operate in this mode, so the indicator won't appear.
In conclusion, it's worth noting that the number 6 is a good sign, indicating modern equipment and a high-quality connection. Understanding how this standard works will allow you to better manage your home network and enjoy high internet speeds without unnecessary worries.
