How to connect to 5GHz Wi-Fi on your phone: Complete instructions for Android and iOS

Are you trying to connect your smartphone to a 5 GHz Wi-Fi network, but it stubbornly refuses to detect it or connects? This problem is familiar to many: despite modern routers supporting dual-band mode (2.4 GHz + 5 GHz), not all phones automatically connect to the faster network. What's the cause and how can you fix it?

Range 5 GHz offers higher data rates and less interference than the crowded spectrum 2.4 GHz, but it has a smaller coverage area and is less effective at penetrating walls. If your phone can't detect the 5 GHz network, router settings, smartphone limitations, or even regional standards may be to blame. In this article, we'll explore all the possible causes and provide step-by-step instructions. Android And iPhoneWe'll also tell you how to check if your device supports 5 GHz.

Before you begin setup, make sure your router is actually broadcasting in the 5 GHz band. Some models disable this mode by default or combine both networks under a single name (SSID). It's also worth checking whether your phone supports this range, especially if you have a budget model or a device older than 2018.

1. How to check if your phone supports 5GHz Wi-Fi

Not all smartphones are equipped with a 5 GHz Wi-Fi module. For example, some budget models Xiaomi Redmi, Samsung Galaxy A-series or old ones iPhone (to iPhone 5) only support 2.4 GHz. How can I tell?

The most reliable way is to look up the technical specifications of your model on the manufacturer's official website. Look for lines like Wi-Fi Support or Wireless NetworksIf standards are indicated there 802.11a, 802.11ac or 802.11ax (Wi-Fi 6/6E), then the 5 GHz band is supported. Unless 802.11b/g/n - Most likely not.

You can also use special applications for network analysis:

• 📱 WiFi Analyzer (Android) - shows available networks and their ranges.
• 📱 Network Analyzer (iOS/Android) - determines the frequencies of neighboring access points.
• 📱 Aida64 (Android) - in the section Network → Wi-Fi Displays supported standards.

If your phone doesn't support 5 GHz, further steps are pointless—you'll have to settle for the 2.4 GHz band or consider buying a new device. But if it does support the 5 GHz band and you still can't see the network, read on.

What to do if your phone doesn't support 5GHz?

If your smartphone doesn't have a 5 GHz Wi-Fi module, but high internet speed is critical to you, consider the following options:

- Use it Powerline adapters (Internet over Ethernet) to connect your phone via an Ethernet adapter (if supported).

- Set up 2.4 GHz guest network on the router with priority for your device (QoS).

- Upgrade your phone to a model that supports 5 GHz (for example, even budget ones Realme Narzo or Poco M-series equipped with dual-band Wi-Fi).

2. Configuring the router for correct 5 GHz operation

Often, the problem isn't with the phone, but with incorrect router settings. Many users aren't even aware that their router can operate in two bands, but by default only broadcasts the 2.4 GHz network or combines both networks under a single name (SSID).

To check and change settings:

1. Connect to the router through the browser by entering in the address bar 192.168.0.1 or 192.168.1.1 (the exact address is indicated on the device sticker).
2. Enter your login and password (usually admin/admin or admin/password).
3. Find the section Wireless Network (Wireless) or Wi-Fi Settings.

Further actions depend on the router model:

• 🔄 Separation of networks: If you have one network name (SSID) for both ranges, separate them. For example, call 2.4 GHz as MyWiFi_2G, and 5 GHz - MyWiFi_5GThis will help the phone clearly “see” both networks.
• 📶 Enabling 5 GHz: In some routers (for example, TP-Link or ASUS) the 5 GHz band may be disabled. Look for the option Enable 5GHz Wireless or similar.
• 🔒 Encryption: Make sure the encryption standard is set for 5 GHz WPA2-PSK or WPA3. Old standards (WEP) may not be supported by modern phones.
• 📡 Channel and width: For stable operation, please select a fixed channel (eg. 36, 40, 44, 48) and width 20/40 MHz or 80 MHz (if supported). Automatic channel selection may cause conflicts.

⚠️ Attention: On some routers (for example, Zyxel Keenetic or MikroTik) 5 GHz settings may be hidden in the section "Additional settings" or Operating modeIf you can't find the options you need, check the documentation for your model.

After changing the settings, be sure to reboot the router and try connecting to the 5 GHz network again. If the problem persists, proceed to the next section.

3. Connecting to 5GHz Wi-Fi on Android

If the router is configured correctly, but the phone still does not see the 5 GHz network, the problem may be in the settings AndroidHere are step-by-step instructions for most devices (using the example Samsung Galaxy, Xiaomi Redmi, Google Pixel):

1. Open "Settings" and go to the section «Wi-Fi».

2. Make sure Wi-Fi is turned on. If the 5 GHz network is not listed, tap "Additionally" (or "More") and select Wi-Fi Range.

3. In some firmware (for example, MIUI on Xiaomi) you need to enable the option Show 5 GHz networks or 5 GHz mode.

4. If there is no option, try adding the network manually:

• Click Add Network.
• Enter the network name (SSID) manually (exactly the same as it is specified in the router settings for 5 GHz).
• Select the security type (WPA2-PSK or WPA3).
• Enter the password and save.

If the network still does not appear, try the following:

• 🔄 Restart your phone - sometimes this helps to reset Wi-Fi module errors.
• 📱 Reset network settings: go to Settings → System → Reset → Reset Wi-Fi/Bluetooth settings.
• 🔧 Update the firmware: come in Settings → Software Update and check if the version is up to date.

⚠️ Attention: On some phones with custom firmware (for example, LineageOS) 5 GHz support may be disabled by default. In this case, manual editing of configuration files or installation of a special module will be required. Magisk.

4. Connect to 5GHz Wi-Fi on iPhone

Devices Apple They usually work well with 5GHz networks, but can sometimes have problems, especially on older models (iPhone 5/5S/SE 1st generation) or after iOS updates. Here's what to do:

1. Open "Settings" and select «Wi-Fi».

2. Make sure the Wi-Fi slider is turned on. If the 5 GHz network isn't showing up, try:

• 🔄 Forget the network: click on the icon «i» next to the network name and select Forget this network. Then reconnect.
• 📱 Reset network settings: go to Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings.
• 🔧 Update iOS: come in Settings → General → Software Update.

If your iPhone still can't see the 5GHz network, check the following:

• 📡 Regional settingsSome countries (such as Japan or Israel) use non-standard 5 GHz channels. Make sure your router is configured to use the channels supported in your region.
• 🔒 Router settings: some routers (eg. ASUS RT-AC68U) have the option Enable MU-MIMO or Beamforming, which may conflict with your iPhone. Try temporarily disabling it.

iPhone 12 and later (with Wi-Fi 6 support) may have trouble connecting to 5GHz networks if the router has the "Wi-Fi 6" mode enabled. 802.11r (Fast Roaming)Disable it in your router settings.

5. Common problems and their solutions

Even if everything is configured correctly, a 5 GHz connection may be unstable. Let's look at typical scenarios and how to resolve them:

If none of the above methods helped, try the following:

• 🔌 Reset your router to factory settings and set it up again.
• 📲 Check your phone for hardware problems — the Wi-Fi module may be faulty.
• 🔧 Update your router firmware - outdated software may contain errors.

⚠️ Attention: If you use mesh system (For example, Google Nest Wi-Fi or TP-Link Deco), make sure all nodes are configured to the same band. In some cases, the main router broadcasts 5 GHz, while the extenders only broadcast 2.4 GHz.

6. Alternative connection methods if 5 GHz doesn't work

If you've exhausted all options and still can't connect to 5 GHz, consider these alternative solutions:

1. Use 2.4 GHz with QoS priority

Configure it on your router Quality of Service (QoS) So your phone gets the maximum bandwidth in the 2.4 GHz band. This won't give you the same speed as 5 GHz, but it will improve stability.

2. Connect via USB/Ethernet adapter

Some phones (eg. Samsung Galaxy S/Note or iPhone with Lightning port) support internet connection via adapter USB-LAN or USB-Wi-FiThis is a rare solution, but it works if speed is critical.

3. Set up a 5 GHz guest network

Some routers only allow you to create a separate guest network in the 5 GHz band. Try connecting to it—your main network may be conflicting with your phone's settings.

4. Use a 5 GHz repeater

If the 5 GHz signal is weak, install a repeater (eg. TP-Link RE605X), which will rebroadcast the network in the required range closer to your phone.

7. How to improve the 5 GHz signal in your home

The 5 GHz band has a smaller coverage area than 2.4 GHz, so the signal may drop out in distant rooms. Here are some ways to improve the situation:

• 📡 Correct placement of the routerPlace it in the center of your home, away from walls and metal objects. Avoid placing it near microwaves or cordless phones.
• 🔄 Use a Mesh system: If you have a large home, consider purchasing a mesh system (eg. Netgear Orbi or ASUS ZenWiFi), which evenly covers the entire area.
• 📶 Adjust the transmit power: Some routers allow you to increase the 5 GHz signal strength (optional) Transmit Power). However, this may cause the device to overheat.
• 🔌 Upgrade your antennas: If your router supports removable antennas, replace them with more powerful ones (for example, with gain 9 dBi).

It's also worth checking if nearby networks are interfering. To do this, use apps like WiFi Analyzer (Android) or AirPort Utility (iOS). If the channel is overloaded, change it in the router settings to a less busy one (for example, with 36 on 149, if supported).

FAQ: Frequently asked questions about connecting to 5GHz Wi-Fi

My phone sees the 5 GHz network, but the speed is slower than on 2.4 GHz. What's the problem?

This can happen for several reasons:

• The router uses a narrow channel width (for example, 20 MHz instead of 40/80 MHz).
• The router settings have enabled compatibility mode for older devices (802.11n instead of 802.11ac/ax).
• The 5 GHz signal is too weak - try moving closer to the router or using a repeater.

Check your router settings and change the channel width to 40 MHz or 80 MHz, and also include the standard 802.11ac (or Wi-Fi 6, if supported).

On mine Xiaomi Redmi Note 8 There is no option to enable 5 GHz. What should I do?

Devices of the series Redmi Note 8/8T They support 5 GHz, but in some regions (for example, in Russia) this feature may be disabled by software. Try:

• Update the firmware to the latest version.
• Reset network settings (Settings → System → Reset → Reset Wi-Fi).
• Install custom firmware (for example, Pixel Experience), if the warranty is not important.

If nothing helps, check your router settings - the problem may be on its end.

Is it possible to force the phone to always connect to 5GHz instead of 2.4GHz?

Yes, but the methods depend on the phone model:

• On Android: separate the networks on the router (different SSID for 2.4 GHz and 5 GHz) and connect only to 5 GHz. Or use apps like WiFi Manager, which allow you to prioritize networks.
• On iPhone: Disable automatic connection to 2.4 GHz in the router settings (if there is such an option) or forget the 2.4 GHz network in the phone settings.

Why did my phone stop seeing 5 GHz after updating the firmware?

Sometimes updates can cause Wi-Fi issues. Try:

• Reset network settings.
• Roll back to the previous firmware version (if possible).
• Contact a service center - the Wi-Fi module may need to be reflashed.

Also check user forums for your model - this may be a known issue that already has a solution.

Which 5GHz channel is best for maximum speed?

The optimal channels depend on your region and airtime congestion. In most countries, the following are recommended:

• 36–48 - lower range (less susceptible to interference, but may overlap with radars).
• 149–165 - upper range (less loaded, but not all devices support it).

Use the app WiFi Analyzerto see which channels are the least busy in your environment.
