How to Change Wi-Fi Bands on iPhone: A Complete Guide with the Nuances for iOS 17 and Later

Have you noticed that your iPhone Has your Wi-Fi connection become slower, frequently dropping the network, or showing low speeds despite a stable signal? The cause may be suboptimal Wi-Fi frequency, which the device uses. Modern routers broadcast on several bands simultaneously— 2.4 GHz, 5 GHz and even 6 GHz (For Wi-Fi 6E), But iPhone does not always choose the fastest or most stable one.

In this article we will look at how Manually change the Wi-Fi frequency on an iPhone, even if iOS hides this option in the default settings. Let's talk about the differences between the bands and when it's worth switching. 5 GHz on 2.4 GHz (and vice versa), and we will also consider Hidden iOS 17+ Features for Managing Network ConnectionsLet's take a closer look at the nuances for new models - from iPhone 12 to iPhone 15 Pro Max, where is the support Wi-Fi 6/6E adds additional features.

Why does the iPhone choose its own Wi-Fi frequency and when is this bad?

By default iPhone uses technology Band Steering (if supported by the router), which automatically switches the device between 2.4 GHz And 5 GHz depending on:

• 📶 Signal level - with poor coverage 5 GHz (which is worse at passing through walls) the phone can “jump” onto 2.4 GHz.
• 🚀 Network loads - if on 2.4 GHz too many devices, iOS will try to switch to a less loaded one 5 GHz.
• 🔋 Energy consumption — 5 GHz consumes battery faster, so it can be used in power saving mode 2.4 GHz.

However, automatic selection is not always optimal. For example:

• 🏠 In a big house with thick walls 5 GHz may "disappear" in distant rooms, but iPhone stubbornly holds on to it instead of switching.
• 🎮 When playing online games or streaming 4K video 2.4 GHz gives high pings due to overload, but the phone does not switch to 5 GHz.
• 🔄 After updating the router firmware or changing channels, the network may work worse, but iPhone does not adapt to changes.

⚠️ Attention: Starting from iOS 14Apple has removed the option to manually select a Wi-Fi frequency from the default settings. However, workarounds remain, which we'll discuss below.

How to Check What Wi-Fi Band Your iPhone Is Using Right Now

Before changing the settings, you need to understand what frequency your connection operates on. iOS There is no built-in tool for this, but there are several ways:

Method 1: Via the app WiFi Analyzer (for free)

1. Download from App Store application WiFi Analyzer (or similar: NetSpot, Fing).

2. Open it and connect to your network. Tab Connection will show the current frequency (2.4 GHz or 5 GHz), as well as the channel, width and signal level.

Method 2: Through the router settings

1. Go to the router's web interface (usually at 192.168.0.1 or 192.168.1.1).

2. Find the section DHCP Clients or Connected devices - your MAC address will be indicated there iPhone and the frequency it is connected to.

Method 3: Through Console on Mac (for advanced users)

If you have Mac, connected to the same network:

1. Open Console (through Spotlight or Programs → Utilities).
2. Enter in search awdl or Wi-Fi — information about the current connection may be displayed in the logs.

💡 Clue: If your network name has suffixes like _5G or _2G, this is a clear sign that the router is splitting frequencies. In this case, iPhone connects to the network you selected manually.

How to Force Change Wi-Fi Band on iPhone: 4 Working Methods

Since Apple has removed the direct option to switch frequencies, you'll have to use workarounds. Let's look at all the current methods for iOS 17 and newer.

Method 1: Separating networks on a router (the most reliable)

If your router supports SSID frequency division (most modern models can do this), do the following:

1. Go to your router settings (usually through a browser) 192.168.0.1 or 192.168.1.1).
2. Find the section Wi-Fi → Wireless network settings.
3. Activate the option Split 2.4 GHz and 5 GHz (or Enable Separate SSID).
4. Give the networks different names, for example:
   • MyWiFi_2G - For 2.4 GHz;
   • MyWiFi_5G - For 5 GHz.

Save the settings and reconnect iPhone to the desired network manually.

✅ Pros:

• 🔧 Works on all models iPhone and versions iOS.
• 📱 Allows you to flexibly switch between frequencies without additional applications.

❌ Cons:

• 🔄 You will have to manually select a network as you move around the house.
• 📡 Some routers do not support SSID separation (especially budget models).

Method 2: Using the app WiFi Assist Control (for iOS 14–17)

Application WiFi Assist Control (available in App Store) allows you to disable automatic switching between 2.4 GHz And 5 GHz, forcing iPhone hold on to the selected frequency.

Instructions:

1. Download and install WiFi Assist Control.
2. Open the app and allow it to access the VPN (this is necessary for it to work).
3. Enable the option Lock Wi-Fi Band and select the desired frequency.
4. Reconnect to the network.

⚠️ Note: The app creates a local VPN but does not share your data with third parties. However, after using it, remember to disable the VPN in the settings (Settings → VPN), so as not to block other traffic.

Method 3: Reset network settings (radical method)

If iPhone If your device is stuck on a non-optimal frequency and won't switch, try resetting your network settings:

1. Go to Settings → General → Transfer or reset iPhone.
2. Select Reset → Reset network settings.
3. After rebooting, reconnect to Wi-Fi - the phone may select a different frequency.

⚠️ Important: This method will reset all saved Wi-Fi passwords, as well as VPN and cellular settings. Use it only if other methods have failed.

Method 4: Manually specifying a channel (for advanced users)

If your router supports manual channel assignment, you can "push" iPhone to the desired frequency:

1. Find the section in your router settings Wi-Fi → Channel.
2. For 2.4 GHz select channels 1, 6 or 11 (they are the least overloaded).
3. For 5 GHz select channels 36, 40, 44 or 48 (they are supported by all iPhone).
4. Save the settings and reconnect iPhone.

📌 Note: On iPhone 12 and newer (with Wi-Fi 6) you can use channels 149–165 For 5 GHz, but they may not be supported by older devices.
