How to Change Wi-Fi Protocol on Your Phone: A Complete Guide for Android and iOS

Modern smartphones automatically select the optimal Wi-Fi protocol when connecting to the network, but sometimes manual configuration can help solve problems with slow internet, connection drops, or incompatibility with an outdated router. For example, if your iPhone 15 Pro or Samsung Galaxy S24 cannot connect to the network with the protocol 802.11b, but the router doesn't support it Wi-Fi 6 (802.11ax), you'll have to manually adjust the settings. In some cases, changing the protocol can increase speed by 30-50% or reduce lag in online games.

However, not all phones provide direct access to these settings. Manufacturers often hide them in the "developer" settings or block them entirely for regular users. In this article, we'll look at how to change the Wi-Fi protocol on phones with Android And iOS, what limitations exist, and what to do if the options you need aren't available in the menu. You'll also learn how to check your current connection protocol and which one is best for various tasks—from watching videos to 4K streaming.

⚠️ Attention: Some methods require superuser rights (root (on Android) or using third-party utilities. This may void your warranty or cause device instability. Back up your data before changing settings.

What is the Wi-Fi protocol and why should it be changed?

The Wi-Fi protocol is a standard for wireless data transmission that determines speed, range, and device compatibility. The most common versions today are:

  • 🔄 802.11b/g — obsolete protocols (up to 54 Mbit/s), used in rare cases for compatibility with older devices.
  • ⚡ 802.11n (Wi-Fi 4) — supports up to 600 Mbps, operates at 2.4 and 5 GHz frequencies.
  • 🚀 802.11ac (Wi-Fi 5) — up to 3.5 Gbps, 5 GHz only, better for high-load networks.
  • 💎 802.11ax (Wi-Fi 6/6E) — up to 9.6 Gbps, supports OFDMA and MU-MIMO, optimized for many devices.

Reasons for changing the protocol:

  1. The router does not support modern standards (for example, only 802.11n, and the phone is trying to connect via 802.11ac).
  2. Unstable connection due to interference at 2.4 GHz (solution: forced transition to 5 GHz with 802.11ac/ax).
  3. Corporate network restrictions where only a specific protocol is allowed.
  4. Performance testing (e.g. speed comparison on Wi-Fi 5 And Wi-Fi 6).

Critical Feature: On iPhone (including 2026 models) there is no official way to forcefully change the Wi-Fi protocol. All settings are managed automatically by the system. iOSWorkarounds require jailbreaking or specialized software.

How to check the current Wi-Fi protocol on your phone

Before changing settings, it's helpful to know which protocol is currently being used. The methods vary depending on Android And iOS.

On Android:

  1. Open the app Wi-Fi Analyzer (For example, WiFi Analyzer from farproc or NetSpot).
  2. Connect to your network and find it in the list.
  3. The connection details will indicate the protocol (for example, 802.11ac or Wi-Fi 5).

On iPhone:

IN iOS There is no built-in tool for viewing the protocol. Use third-party utilities:

  • 📱 AirPort Utility (hidden feature: tap the Wi-Fi icon in the upper right corner, then hold your finger on the network name - a window with details, including the protocol, will appear).
  • 🌐 Speedtest by Ookla (after the speed test, it shows the connection type in the "Details" section).

Changing the Wi-Fi Protocol on Android: A Step-by-Step Guide

On most phones with Android 10–14 The protocol settings are hidden. Let's look at two methods: through the developer menu and using third-party applications.

Method 1: Developer menu (without root)

  1. Enable developer mode: go to Settings → About phone → Build number and click on it 7 times.
  2. Return to Settings → System → Developer Options.
  3. Find the option Wi-Fi settings or Wi-Fi verbosity logging (names vary depending on firmware).
  4. Select Wi-Fi frequency band and set your preferred protocol (eg. 5 GHz (802.11ac)).

Method 2: Wi-Fi Management Apps (Requires Root)

If the developer menu does not provide the options you need, use:

  • 🛠️ WiFi Master Key (allows you to select a protocol when connecting to a network).
  • 🔧 SetWiFi (for advanced users, supports forced standard change).

⚠️ Attention: On phones with chips Qualcomm (For example, Snapdragon 8 Gen 3) Changing the protocol may reduce connection stability if the router does not support the selected standard. Before changing, check the router documentation for compatibility.

Features of settings on phones of different brands

Manufacturers are modifying Android, so the path to Wi-Fi settings may vary. Let's look at the nuances for popular brands.

Samsung (One UI 6.0+):

On Galaxy S23/S24 and other flagships:

  1. Go to Settings → Connections → Wi-Fi.
  2. Click on the current network and select Additionally.
  3. If option Frequency range available, select 5 GHz For 802.11ac/ax.

Xiaomi (MIUI 14+):

On Redmi Note 13 or POCO X6:

  • 🔍 Turn on Developer mode (as described above).
  • In the developer menu, find Wi-Fi settings and activate Forced use of 5 GHz.

Google Pixel (Android 14):

On Pixel 8 Pro:

Protocol options are not available in the standard interface. Use ADB commands: 

adb shell settings put global wifi_frequency_band 1

Where 1 - automatic selection, 2 - only 2.4 GHz, 3 - only 5 GHz.

What to do if there is no option to change the protocol?

On some phones (eg. Realme or Oppo) The manufacturer blocks access to Wi-Fi settings. In this case, two options remain:

1. Use a router that supports the required protocol (for example, buy TP-Link Archer AX73 For Wi-Fi 6).

2. Install custom firmware (for example, LineageOS), but this will void the warranty.

How to Change Wi-Fi Protocol on iPhone (Workarounds)

As mentioned earlier, iOS doesn't allow you to manually select a Wi-Fi protocol. However, there are indirect methods for influencing the connection:

Method 1: Force connection to 5 GHz

If the router broadcasts two networks (2.4 and 5 GHz) with the same name (SSID), iPhone will automatically select the faster protocol. To force it to use 802.11ac/ax:

  1. Rename the 5GHz network on your router (e.g. add a suffix _5G).
  2. On iPhone Connect to this network manually.

Method 2: Using a Configuration Profile

For corporate users:

  • 📄 Ask your network administrator to create a profile with fixed Wi-Fi settings (via Apple Configurator).
  • 📱 Set the profile to iPhone via email or MDM system.

⚠️ Attention: On iPhone With jailbreak you can install tweaks like WiFi Booster, but this violates security policy Apple and may cause the device to become bricked when updating. iOS.

Common problems and their solutions

Problem 1: After changing the protocol, the phone does not connect to Wi-Fi.

Solution:

  • 🔄 Restart your router and phone.
  • 📡 Check if your router supports the selected protocol (for example, 802.11ax requires Wi-Fi 6 router).
  • 🔧 Reset network settings on your phone: Settings → System → Reset → Reset Wi-Fi, mobile networks, and Bluetooth.

Problem 2: The speed did not increase after switching to 802.11ac.

Solution:

Possible reasons:

  1. The 5 GHz channel is congested (use the app WiFi Analyzer, to find a free channel).
  2. The router is limiting the speed (check QoS settings).
  3. The phone is too far from the router (the 5 GHz signal penetrates walls worse).

FAQ: Answers to frequently asked questions

Is it possible to change the Wi-Fi protocol on a phone without rooting?

On most phones with Android - Yes, through the developer menu. iPhone — no, only indirect methods (for example, separating 2.4 and 5 GHz networks).

Which Wi-Fi protocol is best for online gaming?

To minimize ping (ping) choose 802.11ac (5 GHz) or 802.11ax (Wi-Fi 6). Avoid 2.4 GHz due to high latency.

Why did Wi-Fi settings disappear after an Android update?

Manufacturers often simplify the interface in new firmware versions. Try resetting your network settings or using ADB commands to restore the settings.

Is it possible to iPhone force enable Wi-Fi 6?

No, iOS automatically selects the best protocol. If the router supports 802.11ax, the phone will connect via it without any additional actions.

Is it harmful to change Wi-Fi protocol frequently?

No, but this may cause temporary connection interruptions. It's not recommended to change protocols more than once a day.
