iPhone 11 became the first smartphone from Apple, which received standard support Wi-Fi 6 (802.11ax) — a revolutionary upgrade to wireless networks, promising increased speed, lower latency, and better performance in congested environments. However, many users are finding that their device won't connect to the sixth-generation network, even though their router supports it. What's wrong?
The problem lies in the implementation features Wi-Fi 6 V iOS and equipment settings. Unlike Android- devices where the standard is activated automatically, iPhone requires several conditions to be met: proper router configuration, updated firmware, and the absence of software restrictions. In this article, we'll look at how Force Wi-Fi 6 on iPhone 11, check its operation and eliminate typical errors.
Why doesn't my iPhone 11 automatically connect to Wi-Fi 6?
On paper iPhone 11, 11 Pro And 11 Pro Max fully compatible with the standard 802.11ax (This is the official name of Wi-Fi 6). However, in practice, users often see the message in the network settings Wi-Fi 5 or 802.11acThere are several reasons:
- 🔄 Backward compatibility: iOS By default, it selects the most stable mode, not the fastest one. If the router supports both standards, the smartphone may become stuck
Wi-Fi 5due to better compatibility. - ⚙️ Incorrect router settings: many models (especially budget ones) turn off Wi-Fi 6 by default or require manual activation in the admin panel.
- 📱 iOS limitations: Apple artificially blocks the use of some functions Wi-Fi 6 (For example,
OFDMAor1024-QAM) on older firmware versions. - 🔋 Energy saving: in power saving mode iPhone may prefer less resource-intensive standards.
In addition, some providers (especially in Russia and the CIS) still use outdated authentication protocols (WPA2-PSK instead of WPA3), which do not allow for the full exploitation of opportunities Wi-Fi 6Check the security type used on your network—this is critical for proper operation.
How to Check if Your Router Supports Wi-Fi 6
Before setting up iPhone 11, make sure that your router is even capable of distributing the network according to the standard 802.11axHere's how to do it:
- Look at the model on the case: There should be an inscription on the sticker on the back or bottom of the device
Wi-Fi 6,802.11axorAXxxxx(For example, TP-Link Archer AX6000). - Log in to the admin panel: enter in browser
192.168.0.1or192.168.1.1, log in (usually login/password -admin/admin) and find the sectionWireless SettingsorWireless mode. - Look for a mention of the standard: in the settings there should be a menu with a choice of operating mode (
Wireless Mode), where options are available802.11axorWi-Fi 6.
If your router was released before 2019, it most likely does not support Wi-Fi 6. The exception is the flagship models from ASUS, Netgear or Ubiquiti, which have received the firmware update. A full list of compatible devices can be found on the manufacturers' websites.

Step-by-step instructions: how to enable Wi-Fi 6 on iPhone 11
If the router is compatible, we proceed to setup. iPhone. Important: Wi-Fi 6 is activated automatically, if all conditions are met. But sometimes you need to give the system a little nudge. Follow this algorithm:
Update iOS to the latest version|Restart your iPhone and router|Make sure your router is using 802.11ax mode|Disable VPN and power saving modes-->
- Update iOS:
Go to
Settings → General → Software UpdateMinimum version for full support Wi-Fi 6 —iOS 14.2If an update is available, install it. - Reset network settings:
Sometimes iPhone "remembers" old connection settings. To reset them, go to
Settings → General → Transfer or reset iPhone → Reset → Reset Network SettingsAfter this, you will have to re-enter your Wi-Fi password. - Enable 802.11ax mode on your router:
Find the section in the router admin panel
WirelessorWireless network. Set the parameterWireless Modein meaning802.11axorWi-Fi 6Save the settings and reboot the device. - Disable legacy compatibility:
Some routers have an option
Legacy ModeorFast compatibility- it is needed turn off, otherwise the smartphone will connect viaWi-Fi 5. - Check the security type:
Make sure the network is secured with a protocol
WPA3(NotWPA2!). Otherwise iPhone can ignore Wi-Fi 6 due to encryption problems.
After completing these steps, reconnect to the network. To ensure the connection is successful, Wi-Fi 6, use the app WiFi SweetSpots (available in App Store) or check the speed through Speedtest - with the correct settings it should increase by 20-40% compared to Wi-Fi 5.
Common mistakes and their solutions
Even after proper setup Wi-Fi 6 may not work. Let's look at the most common problems and how to fix them:
- 🔌 The router is not distributing Wi-Fi 6.:
Check if the mode is enabled
802.11axin the admin panel. On some models (for example, TP-Link Archer C6) this option is hidden in the sectionAdvanced → Wireless. - 📶 Weak signal at 5 GHz:
Wi-Fi 6 works only in the range
5 GHz. If your iPhone connects to2.4 GHz, in the router settings, disable this frequency or set different names for the networks (MyWiFi_2GAndMyWiFi_5G). - ⚡ Low speed despite Wi-Fi 6:
The problem may be in the channel: switch to
160 MHz(if your router supports it) or select the channel manually (for example,36or149) instead ofAuto. - 🔒 WPA3 doesn't work:
Some devices (especially older ones) do not support
WPA3Temporarily return toWPA2/WPA3 Mixedor update your router firmware.
⚠️ Attention: If after switching on Wi-Fi 6 other devices on the network started to work worse, return the router settings to 802.11acPerhaps your router can't handle simultaneous operation in two standards.
How to Check if Your iPhone 11 Is Actually Using Wi-Fi 6
Visually determine the connection standard in iOS impossible - unlike Android, where the icon is displayed next to the network name 6 or 6EHowever, there are several ways to confirm use. 802.11ax:
- Via the app AirPort Utility:
Download it from App Store, open and press
Wi-Fi Scan(in the top menu). In the results, look for your network - if in the columnProtocolindicated802.11ax, everything works. - MAC address analysis:
In the same utility AirPort Utility take a look
BSSIDyour network. If the router supports Wi-Fi 6, its MAC address will be displayed with the suffix:ax(For example,00:1A:2B:3C:4D:5E:ax). - Speed test:
Launch Speedtest on iPhone and compare the results with other devices on the same network. Wi-Fi 6 the speed should be 30-50% higher (under ideal conditions - up to
1.2 Gbps). - Router logs:
Find the section in the router admin panel
Connected DevicesorDHCP ClientsNext to iPhone 11 must be specified802.11axorWi-Fi 6.
What to do if none of the methods worked?
If all tests show Wi-Fi 5, despite the correct settings, the problem may be due to hardware limitations. Some parties iPhone 11 (especially the early ones) had a defect in the module Wi-Fi, which blocked work with 802.11axIn this case, the only solution is to replace the module at a service center.
iPhone 11 Wi-Fi 5 vs. Wi-Fi 6: Is It Worth the Upgrade?
In practice, the differences between standards aren't always noticeable. Here's an objective comparison:
| Parameter | Wi-Fi 5 (802.11ac) | Wi-Fi 6 (802.11ax) |
|---|---|---|
| Max. speed | to 866 Mbps (on iPhone 11) |
to 1.2 Gbps (theoretically) |
| Latency (ping) | 10–30 ms |
1–10 ms (thanks to OFDMA) |
| Working in crowded networks | Speed drops when there are 10+ devices | Stable operation with 50+ devices |
| Energy consumption | High (constant channel search) | Low (technology TWT) |
| Support in Russia | All routers and devices | A compatible router is required (since 2019) |
Critical point: on the iPhone 11, the Wi-Fi 6 standard only works in the 5 GHz band. If your router doesn't support this band or you've forcibly disabled it, your smartphone will never connect via 802.11ax.
Conclusion: transition to Wi-Fi 6 justified if:
- 📊 You need maximum speed for downloading large files or streaming
4K/8K. - 🏠 You have 10+ devices (smartphones, smart devices, laptops) working on your network simultaneously.
- 🎮 You play online games where minimal latency is important (
ping).
In all other cases, the difference will be minimal, and the adjustment may lead to network instability.
Wi-Fi 6 FAQ for iPhone 11
