How to Switch to 5GHz Wi-Fi on Your Phone: Instructions for Android and iPhone

Range 5 GHz promises faster internet speeds, less interference, and a more stable connection than traditional 2.4 GHzBut many users face a problem: the phone stubbornly connects only to a slow network, ignoring the available high-band channel. Why does this happen and how can you force your smartphone to use it? Wi-Fi 5 GHz?

In this article, we will look at how to check the range support of your device, configure the router for correct operation with 5 GHz, and also force the selection of the desired network on Android And iPhoneYou will also learn what Hidden settings in the firmware of some brands (Samsung, Xiaomi, Huawei) can block the connection to 5 GHz, and how to bypass them without risking your device.

Spoiler alert: in 90% of cases, the problem isn't with the phone, but with incorrect router settings or outdated firmware. But first things first.

Checking if your phone supports 5 GHz

Before attempting to connect to the network 5 GHz, make sure your smartphone supports it. Most modern devices (released after 2016) are equipped with dual-band Wi-Fi modules, but there are exceptions—especially among budget models.

How to check:

• 📱 Android: Go to Settings → About phone → Model information (or Hardware information). Look for lines like "Wi-Fi 5 (802.11ac)" or Dual-band Wi-Fi. If only specified 802.11n - your device only works on 2.4 GHz.
• 🍎 iPhone: All models starting from iPhone 5 (2012) support 5 GHzTo check, please look at Settings → General → About → Model and check with the official specification on the Apple website.
• 🔍 Universal method: Install the application WiFi Analyzer (Android) or Network Analyzer (iOS) They will show all available networks with their range.

If your phone does not support 5 GHz, further actions are pointless - you will need to either change the device or use an external Wi-Fi adapter (for some Android smartphones with OTG support).

Configuring a router to work with 5 GHz

Even if the phone supports it 5 GHz, the router may be configured so that the network is simply not visible for connection. Common causes:

• 🔌 Range disabled 5 GHz in the router settings.
• 🔒 Network is hidden (broadcast SSID is disabled).
• 📶 An incompatible security standard is used (e.g. WEP instead of WPA2/WPA3).
• 🔄 Channel 5 GHz overloaded or blocked by the regulator (in some countries channels 100-140 are limited).

To fix this:

1. Open your router's control panel (usually at 192.168.0.1 or 192.168.1.1).
2. Go to the section Wi-Fi or Wireless network.
3. Find the settings for the range 5 GHz (may be called "5GHz Wireless" or "Band Steering").
4. Make sure that:
• 🔘 Mode enabled 802.11a/n/ac (or 802.11ax for Wi-Fi 6).
• 🔘 Channel width is set to 20/40/80 MHz (car).
• 🔘 Channel selected manually (recommended) 36, 40, 44 or 48 for minimal interference).
• 🔘 Broadcast SSID (network visibility) is enabled.

Save the settings and reboot the router.

5 GHz band enabled|Compatible standard selected (802.11ac/ax)|Channel width of at least 40 MHz|SSID visible for connection|Channel not overloaded (checked in WiFi Analyzer)-->

⚠️ Attention: In some countries (for example, in Russia) channels 5 GHz Channels above 100 may require registration for legal use. If your router doesn't show networks on high channels, check local regulations or switch to channels 36-64.

Force 5GHz connection on Android

If the router is configured correctly, but the phone still clings to 2.4 GHz, try these methods:

Method 1: Split SSIDs

Many routers merge networks by default. 2.4 GHz And 5 GHz under one name (function Band Steering). This is convenient, but it often results in devices getting stuck on a less busy but slower band. Solution:

1. Set different names (SSIDs) for each band in your router settings. For example:
   • MyWiFi_2G For 2.4 GHz;
   • MyWiFi_5G For 5 GHz.

Connect manually to the network with the suffix _5G.

Method 2: Band Priority in Wi-Fi Settings

Some firmware (for example, on Samsung or Xiaomi) allow you to set the priority of the range:

1. Open Settings → Wi-Fi.
2. Tap on the current network and select Change network (or Additionally).
3. Find the option Wi-Fi Range or "Band" and select 5 GHz.
4. Save the changes.

Method 3: Reset network settings

Sometimes a "clean" connection helps:

1. Forget the current network: Settings → Wi-Fi → [tap on the network] → Delete.
2. Turn off Wi-Fi for 30 seconds.
3. Turn on Wi-Fi and reconnect by selecting the network 5 GHz (if SSIDs are separated).

What if there is no range selection option in the settings?

If your Android smartphone does not show the option to manually select 5 GHz, it may mean:

1. The firmware hides this setting (often happens on devices with MIUI, One UI, EMUI shells).

2. The device automatically selects the range, and forced change is impossible without root rights.

3. The router is turned on Band Steering, and the network is physically one (then only separating the SSID will help).

In such cases, try updating your phone or router firmware to the latest version.

5 GHz connection features on iPhone

iPhone It usually automatically connects to the most stable band, but sometimes it gets stuck on 2.4 GHzUnlike Android, iOS doesn't have a direct range selection option, but there are workarounds:

Method 1: Split SSID (like on Android)

The most reliable way is to separate the networks in the router (see the section above) and connect to MyWiFi_5G. The iPhone will remember the priority and will connect to 5 GHz automatically.

Method 2: Reset network settings

If the iPhone stubbornly ignores 5 GHz:

1. Go to Settings → General → Transfer or reset iPhone → Reset.
2. Select Reset network settings.
3. After rebooting, reconnect to Wi-Fi by selecting the network 5 GHz (if SSIDs are separated).

⚠️ Attention: Resetting your iPhone's network settings will delete all saved Wi-Fi passwords, VPNs, and cellular data. Write down any important information beforehand!

Method 3: Force Disable 2.4 GHz on Your Router

If nothing helps, temporarily disable 2.4 GHz in the router settings. The iPhone will be forced to connect to 5 GHz, after which you can turn both ranges back on.

Router brand	Path to 5 GHz settings	Recommended channel
TP-Link	Basic → Wireless → Wireless Settings (5GHz)	36 or 40
ASUS	Wireless → Professional → Band Selection	44 or 48
Keenetic	Wi-Fi → Access Point → 5 GHz Band	100 (if allowed)
Xiaomi	Wi-Fi → Wi-Fi Settings → 5G Wi-Fi	149 (for minimal interference)

Common problems and their solutions

Even after all the settings, the phone may refuse to connect to 5 GHzLet's consider typical scenarios:

Problem 1: The 5GHz network is visible, but does not connect.

Possible reasons:

• 🔐 Incorrect password (check the case!).
• 🛡️ Incompatible security type (eg. WPA3 (not supported by older devices).
• 📡 The distance to the router is too great - 5 GHz has a smaller coverage area.

Solution: Check the security settings on your router (we recommend WPA2-PSK) and try bringing the phone closer to the router.

Problem 2: 5GHz network drops after connecting

This may be due to:

• 🔄 Automatic switching to 2.4 GHz when the signal is weak (function Band Steering).
• ⚡ Unstable power supply to the router (try a different power supply).
• 📵 Interference from other devices (microwaves, wireless headphones).

Solution: Turn it off Band Steering in the router or fix the channel manually (for example, 48).

Problem 3: Slow speed on 5 GHz

If the speed does not meet expectations:

• 📉 Check the channel width - if it is 20 MHz, change to 40 or 80 MHz.
• 🔄 Switch to a less crowded channel (use WiFi Analyzer for analysis).
• 🖥️ Make sure your internet plan supports high speeds.

Additional settings for advanced users

If standard methods don't work, try these tricks:

1. Change the region in the router settings

Some routers limit available channels. 5 GHz depending on the country selected. For example, in Russia By default, channels above 64 may be blocked. To unblock them:

1. In the router control panel, find the section Wireless → Country/Region.
2. Choose a country with less stringent restrictions (eg. USA or Ukraine).
3. Save your settings and check available channels.

⚠️ Attention: Changing your region may violate local radio frequency laws. Use this method at your own risk and only if you are confident in the legality of the selected channel.

2. Updating the router firmware

Outdated firmware may contain bugs that interfere with operation 5 GHz. Update it:

1. Download the latest firmware version from the manufacturer's official website.
2. In the router control panel, find the section Administration → Firmware Upgrade.
3. Download the file and wait for the process to complete (do not turn off the power!).

3. Using applications to force a connection

For Android With root rights there are applications like WiFi Band, which allow you to block 2.4 GHz At the system level. Without root access, this method won't work.

FAQ: Answers to Frequently Asked Questions

My phone can't see the 5 GHz network, even though the router is broadcasting it. What's wrong?

Possible reasons:

• Your phone does not support 5 GHz (check model specifications).
• The router is in the enabled mode 802.11n only (change to 802.11a/n/ac).
• Channel 5 GHz blocked in your country (try changing the channel to 36-48).
• The signal is too weak - move your phone closer to the router.

How do I know what band my phone is connected to right now?

On Android:

• Install the application WiFi Analyzer or Network Signal Info.
• Open it and look at the current network - the range will be indicated there (2.4 GHz or 5 GHz).

On iPhone:

• Long-press the Wi-Fi icon Control center (swipe down from the upper right corner).
• If there is an icon next to the network name "5G" - you are connected to 5 GHz.

Will 5GHz work through walls?

Range 5 GHz passes through obstacles worse than 2.4 GHz. On average:

• Through 1 concrete wall the signal weakens by 30-50%.
• Through 2 walls the connection may be interrupted.
• Metal partitions or mirrors completely block the signal.

Solution: Use Wi-Fi repeaters or mesh systems to boost the signal.

Is it possible to use 2.4GHz and 5GHz at the same time?

Yes, most modern routers support it. dual mode, when both ranges operate in parallel. You can:

• Connect some devices (for example, a smartphone) to 5 GHz for speed.
• Leave 2.4 GHz for devices with low requirements (smart bulbs, sensors).

To do this, the router must have different SSIDs for each range.

Is it true that 5 GHz is harmful to health?

There is no scientific evidence that 5 GHz more dangerous 2.4 GHzBoth ranges are non-ionizing radiation, which does not damage DNA. The radiation power of a Wi-Fi router is hundreds of times lower than that of a mobile phone in call mode. The main thing is to observe standard safety precautions:

• Do not place the router near your sleeping area.
• Turn off Wi-Fi at night if you are not using it.
