How to Switch Wi-Fi to 2.4 GHz on Android: 5 Methods for Any Device

You're trying to connect to an old access point, smart device, or printer, but your Android- the smartphone stubbornly clings only to the network 5 GHzOr does the router broadcast both bands under the same name, and the gadget automatically selects the less stable channel? This problem is familiar to many – modern devices often ignore 2.4 GHz, although this range is still relevant for IoT devices, older laptops, and equipment with limited network support.

In this article you will find 5 proven methods forced switching to 2.4 GHz — from standard settings Android to hidden engineering menus. We'll figure out why a smartphone might not see the network you need, and how to distinguish between bands if they have the same name. SSID, and what to do if the manufacturer has blocked manual settings. You'll also learn which models Samsung, Xiaomi And Realme The most common "glitches" are with the Wi-Fi selection and how to fix this without root rights.

Spoiler: 80% of the time, the problem can be solved in 2 minutes—you just need to know where to look. Let's start with the simplest method.

Why does Android automatically select 5GHz instead of 2.4GHz?

Modern smartphones try to connect to the network by default 5 GHz — and there are 3 good reasons for this:

• 🔹 Speed: 5 GHz provides higher throughput (up to 1300 Mbps against 450 Mbps at 2.4 GHz in standard 802.11n).
• 🔹 Channel congestion: Range 2.4 GHz overloaded with household appliances (microwaves, baby monitors), which creates interference.
• 🔹 Manufacturers' algorithms: Google, Samsung And Qualcomm Optimize firmware for maximum performance, not compatibility.

However, automatic selection is not always justified. Here's when I need to force a switch to 2.4 GHz.:

• 📡 Connect to IoT devices (smart light bulbs Xiaomi Yeelight, cameras TP-Link Tapo, thermostats Nest).
• 🖨️ Printing on old printers (Canon MG3600, HP DeskJet 2130).
• 🎮 Online games on Nintendo Switch or PS4 (5 GHz often gives high ping due to weak signal through walls).
• 🏠 Large coverage area: 2.4 GHz passes through walls and ceilings better.

⚠️ Attention: If your router broadcasts both ranges under one SSID name (For example, MyWiFi without suffixes _2G/_5G), the smartphone will connect to the higher-priority network automatically. In this case, you'll either need to separate the networks in the router settings or use the methods in this article.

Manufacturers Android-devices implement Wi-Fi range management differently. For example, in Samsung Galaxy with shell One UI There is a hidden menu for selecting the frequency, and in the "clean" Android (for example, on Pixel or Nokia) this option may not exist at all. Below, we'll look at universal and brand-specific methods.

Method 1: Separating networks in the router settings (the most reliable method)

If your router is broadcasting 2.4 GHz And 5 GHz under by one name (For example, KEENETIC-123), the smartphone will select the range automatically. The solution is divide the networks in the router control panel. This will force the device to display both networks separately, and you can connect to the desired one manually.

Instructions for popular router models:

After split:

1. On your smartphone, go to Settings → Wi-Fi.
2. Select the network with the suffix _2G (or similar).
3. Enter the password and connect.

⚠️ Attention: Some routers (eg. ZTE or Huawei older models) do not support network separation. In this case, use Method 2 or Method 3 from this article.

Method 2: Force range selection via Developer Mode

If it is not possible to separate networks on the router, try disable 5 GHz support directly in the settings AndroidTo do this you will need to activate Developer mode - a hidden panel with advanced options.

Steps to enable developer mode (if not already enabled):

1. Open Settings → About phone.
2. Find the item Build number (or MIUI version on Xiaomi).
3. Tap on it 7 times in a row. A notification will appear You have become a developer!.

Now let's move on to setting up Wi-Fi:

Activate developer mode (7 taps on “Build number”) | Open “Settings → System → Developer mode” | Find the option “Disable absolute 5 GHz band” or “Wi-Fi frequency band” | Restart the device-->

Further steps depend on the manufacturer:

• 📱 Samsung (One UI): Go to Settings → Developer Mode, find the option Disable absolute 5 GHz band and activate it. After rebooting, the smartphone will only see 2.4 GHz networks, even if they are not separated on the router.
• 📱 Xiaomi/Redmi/Poco (MIUI): In developer mode, find Wi-Fi frequency band and select 2.4 GHz only.
• 📱 Google Pixel, Nokia, Motorola (pure Android): There may not be a forced range selection option. Use Method 3 or Method 4.

If the option you need is not available, try this alternative:

Settings → Connections → Wi-Fi → ⋮ (three dots) → Advanced → Wi-Fi Band

⚠️ Attention: On some devices (eg. Samsung Galaxy S22 With One UI 5.0+) option Disable absolute 5 GHz band It may reset after a firmware update. Check its status after updates.

Method 3: Using apps to force a connection

If in the settings Android There is no range selection option, third-party utilities will come to the rescue. They allow you to manually specify BSSID (unique access point identifier) ​​or block the connection to 5 GHz.

Top 3 verified apps:

Instructions for use WiFi Analyzer:

1. Install the application and open it.
2. Go to the tab AP LIST (list of access points).
3. Find your network - the range will be indicated next to the name (2G or 5G).
4. Tap on the network 2.4 GHz and connect manually.

If the network is not visible:

• 🔄 Restart your router and smartphone.
• 📶 Check if it is hidden SSID in the router settings.
• 🛠️ Update your router firmware (sometimes bugs prevent correct broadcasting) 2.4 GHz).

Method 4: Manual connection via BSSID (for advanced users)

Each access point has a unique identifier - BSSID (MAC address). If your router broadcasts both ranges under one SSID, but with different BSSID, you can manually tell your smartphone which address to connect to.

How to find BSSID:

1. Install the application WiFi Analyzer (cm. Method 3).
2. Open the tab AP LIST.
3. Find your network - there will be a line under its name BSSID (example: A4:17:31:XX:XX:XX).
4. Remember or write down BSSID For 2.4 GHz (usually it differs from the last characters 5 GHz).

How to connect via BSSID:

1. Open Settings → Wi-Fi.
2. Tap on your network and select Change network (or Additionally).
3. Activate the option Additional options (if any).
4. In the field BSSID Enter the MAC address 2.4 GHz-networks.
5. Save and connect.

If the field BSSID absent:

• 📲 On Samsung try this path: Settings → Connections → Wi-Fi → ⋮ → Advanced → Manage networks.
• 📲 On Xiaomi activation may be required Developer mode (cm. Method 2).
• 📲 On the "clean" Android (For example, Pixel) this option may not be available - use Method 5.

⚠️ Attention: Some routers (eg. MikroTik) use the same BSSID for both ranges. In this case, this method won't work—try other methods.

Method 5: Reset network settings (if nothing helps)

If the smartphone stubbornly ignores 2.4 GHz, despite all the manipulations, the last chance is reset network settingsThis will clear all saved connections and settings for Wi-Fi, Bluetooth, and mobile data, returning them to factory defaults.

How to reset network settings:

1. Open Settings → System → Reset (or General settings → Reset on Samsung).
2. Select Reset network settings (not to be confused with Factory reset!).
3. Confirm the action (you may be asked to enter PIN-code or graphic key).
4. After rebooting, connect to the network 2.4 GHz manually.

What will be reset:

• 📶 All saved Wi-Fi networks (you'll have to re-enter passwords).
• 📱 Mobile Internet settings (APN).
• 🔵 Bluetooth connections (devices will need to be paired again).

What NOT will happen:

• 📁 Files, photos, and apps will remain in place.
• 🔧 Your screen, sound, and other system settings will remain unchanged.

What to do if resetting doesn't help?

If your smartphone still connects to 5 GHz after a reset, the problem may be with the router firmware or hardware limitations. Try:

1. Update the router firmware to the latest version.

2. Roll back the Android firmware (if the reset occurred after the update).

3. Use an external Wi-Fi adapter with 2.4 GHz support (via OTG for phones with USB-C).

Common problems and solutions

Even after successfully switching to 2.4 GHz Difficulties may arise. Let's look at typical scenarios and how to resolve them.

Problem 1The smartphone "sees" the network 2.4 GHz, but does not connect.

• 🔹 Check it out security type in the router settings. Some devices do not support WPA3 — switch to WPA2-PSK.
• 🔹 Make sure that in the router Compatibility mode is enabled With 802.11b/g/n (and not only 802.11n).
• 🔹 Try it change channel on 2.4 GHz (recommended: 1, 6 or 11 - they overlap the least).

Problem 2: After rebooting, the smartphone reconnects to 5 GHz.

• 🔹 On Samsung check if the setting has been reset Disable absolute 5 GHz band V Developer mode.
• 🔹 In the Wi-Fi settings, disable the option Auto-connection or Smart switching (if any).
• 🔹 Install the application Tasker and create a task to force connection to 2.4 GHz after reboot.

Problem 3: Low speed on 2.4 GHz.

• 🔹 Check it out channel width in the router settings. For 2.4 GHz optimal value 20 MHz (and not 40 MHz, which may cause interference).
• 🔹 Reduce transmit power router if the signal is too strong (may interfere with neighboring channels).
• 🔹 Turn it off neighboring devices, operating at frequency 2.4 GHz (wireless mice, baby monitors, microwaves).

FAQ: Answers to Frequently Asked Questions

My smartphone can't detect the 2.4 GHz network at all. What's wrong?

Possible reasons:

• 🔹 In the router the 2.4 GHz band is disabled (check your wireless network settings).
• 🔹 Your device does not support 2.4 GHz (rare, but it happens with some models) Google Pixel or flagships Samsung after 2022).
• 🔹 There are laws in force in the country frequency restrictions (for example, in Japan channels 12-14 are banned).
• 🔹 Router firmware failure - try reset it to factory settings.

How do I know which band I'm connected to right now?

Verification methods:

• 📱 In the Wi-Fi settings on Android 12+ Tap on the current network - if there is a line Frequency or Range, it will be indicated there 2.4 GHz or 5 GHz.
• 📊 Install the application WiFi Analyzer - it will show the range next to the network name.
• 🖥️ Go to your router's control panel and look at the list of connected devices (usually the range is indicated there).

Will my Smart TV or smart speaker work if my router only broadcasts 5 GHz?

More likely, No. Majority Smart TV (For example, LG WebOS, Samsung Tizen until 2020), smart speakers (Amazon Echo Dot, Yandex Station) and other equipment support 2.4 GHz only. Exceptions:

• 📺 Samsung QLED 2021+ And LG OLED C2/G2 (support both ranges).
• 🔊 Apple HomePod mini And Google Nest Audio (work on 5 GHz, but can also connect to 2.4 GHz in compatibility mode).

If your router is not broadcasting 2.4 GHz, you will have to either buy a new one (even budget models like TP-Link TL-WR840N support both ranges), or use signal repeater with support 2.4 GHz.

Is it possible to connect to 2.4GHz and 5GHz on one device at the same time?

No, one Wi-Fi connection can only use one range. However, there are workarounds:

• 📶 Use two networks simultaneously (For example, 2.4 GHz for smart devices and 5 GHz for smartphone) via guest access on the router.
• 🔄 Some flagship smartphones (eg. Samsung Galaxy S23 Ultra) support Wi-Fi 6E and can use multiple channels at the same time, but this does not apply to standard 2.4/5 GHz.
• 🖥️ On Windows-you can connect to laptops external Wi-Fi adapter (via USB) for the second connection.

After updating, Android stopped detecting 2.4 GHz. How can I get it back?

This is a common issue after firmware updates, especially on devices Samsung And XiaomiSolutions:

1. Check if the settings have been reset Developer mode (cm. Method 2).
2. Install beta version of the firmware (if available) - sometimes bugs are fixed in future builds.
3. Do it downgrade to a previous version of Android (look for instructions for your model on the forums 4PDA or XDA Developers).
4. If nothing helps, contact service center — the problem may be in the Wi-Fi module driver.

⚠️ Attention: Firmware rollback may result in data loss. Please make a backup copy beforehand. Settings → System → Backup.
