When you turn on modem mode on iPhone, the device turns into a Wi-Fi hotspot, allowing other gadgets to connect to the internet. But few people consider the frequency this distribution operates on— 2.4 GHz or 5 GHzThis affects not only connection speed, but also coverage range, signal resistance to interference, and even smartphone battery life.
In this article we will figure out how iPhone selects the frequency range for distributing Wi-Fi, is it possible to change it manually, and why is it sometimes better to forcefully switch to 5 GHz (or vice versa, stay on 2.4 GHz). You will also learn how to check the current distribution frequency without third-party applications and what to do if devices do not see your network. iPhone.
Spoiler: Apple doesn't give users direct control over frequency selection in the settings, but there are workarounds. Also, not all models iPhone support distribution on 5 GHz, and this is important to consider when connecting older devices.
How does iPhone choose between 2.4 GHz and 5 GHz Wi-Fi frequencies?
By default iPhone automatically determines which frequency to distribute the Internet on, based on several factors:
- 📱 iPhone model - old devices (for example, iPhone 5s or 6) support only 2.4 GHz, and modern ones (starting from iPhone 6s) - both ranges.
- 🔄 Compatibility of connected devices - if a gadget that does not support the access point is connected 5 GHz (for example, some smart light bulbs or old laptops), iPhone can force a switch to 2.4 GHz.
- 📶 Airtime congestion - if there are a lot of networks in the area 2.4 GHz, the system may prefer a less loaded one 5 GHz (if available).
- 🔋 Energy saving - distribution on 5 GHz consumes more battery, so when the charge is low iPhone may give priority 2.4 GHz.
It is important to understand that iPhone does not always use both ranges at the same time (unlike some routers with technology Dual-Band). He chooses one range for distribution, and all connected devices work on it. This means that if your MacBook supports 5 GHz, A smart speaker - only 2.4 GHz, then the entire network will work on 2.4 GHz, limiting the speed for everyone.
Is there a way to force iPhone distribute Wi-Fi strictly to 5 GHz or 2.4 GHz? Officially, no. But there are workarounds, which we'll discuss below.
How to check what frequency my iPhone uses for Wi-Fi?
To find out what range your iPhone To distribute, you don't need to install any third-party apps. Simply use the built-in tools. Windows, macOS or Android.
🖥️ On Windows (via "Network Settings")
1. Connect to an access point iPhone.
2. Open Settings → Network and Internet → Wi-Fi.
3. Click on the network name (e.g. iPhone (YourName)).
4. Scroll down to the section "Properties" - it will be indicated there Network range (2.4 GHz or 5 GHz).
🍎 On macOS (via System Information)
1. Hold Option (⌥) and click on the Wi-Fi icon in the menu bar.
2. Find the line in the drop-down list "Channel" - if the channel number is from 1 to 14, This 2.4 GHz; if from 36 to 165 — 5 GHz.
🤖 On Android (via "Wi-Fi Settings")
1. Connect to the network iPhone.
2. Open Settings → Wi-Fi and tap on the network name.
3. In some firmware (for example, Samsung One UI or MIUI) will be indicated Frequency rangeIf this information is not available, use the app. WiFi Analyzer (free in Google Play).
If none of the methods worked, you can use terminal (on macOS/Linux) or PowerShell (on Windows), but this requires knowledge of commands. For most users, the methods above will suffice.
iPhone Models and Wi-Fi Band Support: A Complete Chart
Not all iPhone support Wi-Fi distribution on 5 GHz. For example, iPhone 5s and older models are limited only 2.4 GHzBelow is a table showing supported ranges for different generations:
| iPhone model | 2.4 GHz support | 5 GHz support | Max. distribution speed |
|---|---|---|---|
| iPhone 5s (2013) | ✅ Yes | ❌ No | up to 72 Mbps |
| iPhone 6 / 6 Plus (2014) | ✅ Yes | ✅ Yes | up to 433 Mbps |
| iPhone 6s / 6s Plus (2015) | ✅ Yes | ✅ Yes | up to 866 Mbps |
| iPhone SE (1st generation) (2016) | ✅ Yes | ✅ Yes | up to 866 Mbps |
| iPhone 7 / 7 Plus and newer | ✅ Yes | ✅ Yes (including Wi-Fi 6 on iPhone 12 and newer) | up to 1.2 Gbps |
Important: Even if your iPhone supports 5 GHz, this doesn't guarantee that tethering will work on this frequency. The system may force a switch to 2.4 GHz if it detects incompatible devices on the network.
If your model iPhone does not support 5 GHzIf you need high speed, consider alternative ways to distribute the Internet:
- 🔌 USB modem (For Windows/macOS) - cable connection eliminates problems with Wi-Fi.
- 📶 Bluetooth Internet (Personal Hotspot) - slower than Wi-Fi, but more stable in conditions of interference.
- 🌐 External router - some models (for example, TP-Link TL-MR3020) can connect to iPhone via USB and distribute Wi-Fi at the required frequency.
Why can iPhone only share Wi-Fi on 2.4 GHz?
If your iPhone stubbornly ignores 5 GHz and distributes the Internet only to 2.4 GHzThere are several reasons for this:
- Old connected devices - if at least one gadget that does not support it is connected to the access point 5 GHz (For example, Amazon Echo Dot 2nd generation or HP LaserJet printer), iPhone switch to 2.4 GHz for compatibility.
- Energy saving settings — when the battery charge is low (
<20%) iOS may limit distribution 5 GHz, since this range consumes more energy. - Driver issues - It's rare, but it happens after an update iOS There are problems with the Wi-Fi module. In this case, resetting the network settings helps (
Settings → General → Transfer or reset iPhone → Reset network settings). - Regional restrictions - in some countries (for example, in Japan) the range 5 GHz has additional channel restrictions. If you travel, this may affect the hotspot's performance.
To check if connected devices are at fault, follow these steps:
Disconnect all devices from the iPhone's hotspot | Restart Personal Hotspot (turn it off and on in Settings) | Check the wireless frequency again | If it's now 5 GHz, one of the disconnected devices is to blame -->
If after turning off all gadgets iPhone still distributes on 2.4 GHz, try:
- 🔄 Restart your iPhone - sometimes this resets the time restrictions.
- 📱 Update iOS — Wi-Fi bugs are fixed in new versions.
- 🔧 Reset network settings (see above).
What to do if your iPhone doesn't see 5 GHz networks at all?
If your iPhone does not detect the network 5 GHz Even when connecting to other routers, the problem may be a hardware failure in the Wi-Fi module. This is typical for devices that have been dropped or exposed to water. In this case, only repair at a service center will help.
How to force iPhone to share Wi-Fi on 5GHz?
Apple There is no direct option to select a range in the settings, but there are a few workarounds:
🔧 Method 1: Change the Access Point Name (SSID)
Some users have noticed that if the network name (Settings → Tethering & Hotspot → Wi-Fi Name) add suffix _5G or _5GHz, iPhone begins to prioritize range 5 GHz. For example:
MyNetwork_5GThis isn't an official method, but it works in some cases. After changing the name, restart tethering.
🔧 Method 2: Use third-party utilities (for advanced users)
On iPhone With jailbreak you can install tweaks like WiFi Booster or NetworkList, which allow you to manually select a range. However, this:
- ⚠️ Voiding the warranty Apple.
- ⚠️ May cause system instability.
- ⚠️ Requires flashing when updating iOS.
This method is not recommended for most users.
🔧 Method 3: Connect an external router
If it is critical for you to distribute the Internet on 5 GHz, Can:
- Buy a compact router with support USB modem (For example, TP-Link TL-MR3020).
- Connect it to iPhone via cable (
Lightning/USB-C → USB). - Configure the router to distribute Wi-Fi 5 GHz.
This solution is more expensive, but more reliable and flexible.
2.4 GHz vs. 5 GHz: Which Band is Better for Sharing with iPhone?
The choice between 2.4 GHz And 5 GHz It depends on your goals. Here's a comparison table:
| Characteristic | 2.4 GHz | 5 GHz |
|---|---|---|
| Coverage range | ✅ Better penetration through walls (up to 50 m indoors) | ❌ The signal is weaker (up to 20-30 m, sensitive to obstacles) |
| Maximum speed | ❌ Up to 150-300 Mbps (depending on the standard) | ✅ Up to 1 Gbps (on iPhone 12 and newer) |
| Interference resistance | ❌ Lots of overlap with other networks (microwaves, Bluetooth) | ✅ Less interference (less frequently used band) |
| Battery consumption | ✅ Lower (more economical for iPhone) | ❌ Higher (especially under heavy load) |
| Compatibility with devices | ✅ Supports all gadgets (even old ones) | ❌ Some IoT devices do not work on 5 GHz |
When is it best to use 2.4 GHz:
- 🏠 If you need maximum range (for example, distribution at a dacha or in a large house).
- 🔌 If you are connecting old devices (printers, smart sockets, speakers).
- 🔋 If the charge iPhone critically low and need to save battery.
When is it best to use 5 GHz:
- 🎮 For online gaming, video calls, or streaming (less lag).
- 💻 If you connect modern laptops or smartphones (high speed).
- 🏢 In conditions of strong interference (apartment buildings, offices).
If you need to connect devices that only work on 2.4 GHz, but at the same time distribute the Internet 5 GHz for the rest, the only solution is to use two separate access points (For example, iPhone + router).
Common problems and solutions when sharing Wi-Fi from iPhone
Internet distribution with iPhone It doesn't always work perfectly. Here are the most common problems and how to solve them:
🚫 Problem: Devices don't see the iPhone network
Possible causes and solutions:
- 🔍 The network is hidden - Check if hidden network mode is enabled in
Settings → Tethering & Personal Hotspot → Wi-Fi Setup. - 📵 Range incompatibility - If iPhone distributes on 5 GHz, and the device only supports 2.4 GHz, the network won't be displayed. The solution is to force switch to 2.4 GHz (turn off all devices that support 5 GHz).
- 🔄 Modem failure - Restart the modem mode or reboot iPhone.
🐢 Problem: Slow upload speed
What to check:
- 📶 Wi-Fi range - if the distribution is on 2.4 GHz, the speed will be limited even with a good signal. Try switching to 5 GHz.
- 📡 Cellular network signal strength - if you have iPhone weak signal
4G/5G, the distribution will slow down regardless of the Wi-Fi range. Check the signal strength in the upper right corner of the screen. - 🔌 Battery charge - at a level below
20%iOS may limit the upload speed. Connect iPhone to charging. - 🛠️ Operator settings Some mobile operators limit data transfer speeds (especially on unlimited plans). Check the terms in your personal account.
🔋 Problem: Battery drains quickly when sharing
Wi-Fi distribution, especially on 5 GHz, drains the battery significantly. To reduce consumption:
- 🔌 Connect iPhone to charge during distribution.
- 📴 Switch to 2.4 GHz (turn off devices that support 5 GHz).
- ⚡ Turn on Low Power Mode (
Settings → Battery), but keep in mind that this may reduce speed.
FAQ: Frequently asked questions about sharing Wi-Fi from your iPhone
❓ Is it possible to simultaneously share Wi-Fi on 2.4 GHz and 5 GHz from one iPhone?
No, iPhone does not support simultaneous distribution on two bands (unlike some routers). It chooses one range for all connected devices. If you need both bands, use an external router connected to iPhone via USB.
❓ Why won't my smart speaker connect to my iPhone as a personal hotspot?
Most likely your column (for example, Amazon Echo or Yandex Station) supports only 2.4 GHz, A iPhone distributes Wi-Fi on 5 GHz. Solution:
- Disconnect all devices connected to the access point iPhone.
- Restart the modem mode.
- Try connecting the speaker again - the network should now be on 2.4 GHz.
How do I increase the Wi-Fi range of my iPhone?
If the signal is weak, try:
- Switch to 2.4 GHz (passes through walls better).
- Place iPhone in the central part of the room (not near metal objects).
- Use Wi-Fi repeater (For example, TP-Link RE305), connected to the network iPhone.
- Turn off other devices that create interference (microwaves, cordless phones).
Please note that the maximum distribution range is iPhone - near 10-15 meters on 5 GHz And 30-50 meters on 2.4 GHz (under ideal conditions).
❓ Why is my iPhone's Wi-Fi connection slower than the 4G speed it shows?
This is normal. Download speed is limited by several factors:
- Wi-Fi range — 2.4 GHz the maximum gives ~150-300 Mbit/s, and 5 GHz — up to 866 Mbit/s (theoretically).
- CPU load — iPhone It is not optimized for the role of a router, so some of the power is spent on processing traffic.
- Operator restrictions — many tariffs have separate limits on data distribution (even if 4G shows high speed).
To check your actual speed, connect your device to iPhone via cable (USB → Ethernet adapter) - this way the losses will be minimal.
❓ Is it possible to share Wi-Fi from an iPhone using the 6 GHz frequency (Wi-Fi 6E)?
No, at the moment (2026) none iPhone does not support distribution to 6 GHz (range Wi-Fi 6E). This technology is only available in some flagship routers and smartphones. Android (For example, Samsung Galaxy S22 Ultra). Apple has not yet announced support 6 GHz for modem mode.
