Introduction

If you have ever wondered How to Turn 5ghz Wifi Off?, you are not alone. Many people need to disable the 5GHz band on their router, computer, or smartphone for troubleshooting, compatibility, or battery-saving reasons. While 5GHz Wi-Fi offers faster speeds and less interference, it does not travel as far as 2.4GHz, and some older devices simply cannot see it. This guide walks you through every practical method to turn off 5GHz Wi-Fi safely and effectively, no matter which device or operating system you use.

What Is 5GHz Wi-Fi?

Wi-Fi networks typically operate on two main frequency bands: 2.4GHz and 5GHz. The 5GHz band provides higher data rates and is less crowded by household appliances like microwaves and cordless phones. However, its signals do not penetrate walls and floors as well as 2.4GHz signals. When you ask How to Turn 5ghz Wifi Off?, you are usually trying to force a connection to the more stable 2.4GHz band or reduce radio interference in a dense environment.

Why You Might Want to Disable 5GHz

There are several legitimate reasons to disable 5GHz Wi-Fi. Older smart home devices, such as certain security cameras, smart plugs, and thermostats, only support 2.4GHz. Gamers sometimes disable 5GHz to reduce latency spikes caused by DFS channels. Office IT teams may turn off 5GHz to standardize connections across legacy hardware. In some cases, disabling 5GHz can also improve battery life on laptops and mobile devices because the radio does not have to search for a weaker high-frequency signal.

Before You Start

Before making changes, note your current network name (SSID) and password. If you disable 5GHz at the router level, devices that only support 2.4GHz will still connect, but dual-band devices may default to 2.4GHz. Back up your router configuration if possible, and ensure you have an Ethernet cable handy in case you lose wireless access during the process.

Disable 5GHz on Your Router

The most thorough way to answer How to Turn 5ghz Wifi Off? is to disable the band directly on your router. This affects every device on the network.

Step-by-Step Router Instructions

  1. Connect your computer to the router via Ethernet or Wi-Fi.
  2. Open a web browser and enter your router’s IP address, commonly 192.168.1.1 or 192.168.0.1.
  3. Log in using your admin username and password.
  4. Navigate to the Wireless Settings or Wi-Fi Settings section.
  5. Look for an option labeled 5GHz, Band, or Radio. It may appear as a separate tab or slider.
  6. Disable the 5GHz radio or uncheck the 5GHz SSID broadcast option.
  7. Save or Apply the changes and reboot the router if prompted.

After the router restarts, only the 2.4GHz network should be visible. If your router uses a single combined SSID, you may need to separate the bands first by giving 2.4GHz and 5GHz different names, then disable the 5GHz one.

Disable 5GHz on Windows 10/11

If you only want to stop your Windows PC from connecting to 5GHz, you can adjust the network adapter settings.

Step-by-Step Windows Instructions

  1. Right-click the Start button and select Device Manager.
  2. Expand Network adapters and right-click your Wi-Fi adapter.
  3. Select Properties, then go to the Advanced tab.
  4. Find the property named Preferred Band, Wireless Mode, or 802.11a/b/g/n/ac/ax.
  5. Set the value to 2.4GHz only or disable 802.11a/n/ac/ax on 5GHz if the driver exposes separate toggles.
  6. Click OK and reconnect to your network.

Some drivers do not expose a direct 5GHz toggle. In that case, you can use the netsh command or third-party Wi-Fi management tools to prefer 2.4GHz. A simple approach is to forget the 5GHz SSID in Windows Settings so the PC no longer auto-connects to it.

Disable 5GHz on macOS

macOS does not provide a simple system-wide toggle for 5GHz, but you can influence band selection through network preferences or router configuration.

Step-by-Step macOS Instructions

  1. Open System Settings (or System Preferences on older macOS).
  2. Go to Network, select Wi-Fi, then click Details or Advanced.
  3. Remove the 5GHz network from the preferred networks list if it appears separately.
  4. Alternatively, use the Wireless Diagnostics tool to monitor band usage.

For a more forceful approach, create a separate 2.4GHz-only SSID on your router and connect your Mac to that network. macOS will then stay on 2.4GHz as long as that SSID is available and prioritized in your network order.

Disable 5GHz on Android

Android phones usually connect to whichever band offers the strongest signal. To force 2.4GHz, you can either use router-side separation or Android developer options.

Step-by-Step Android Instructions

  1. Ensure your router broadcasts separate SSIDs for 2.4GHz and 5GHz.
  2. On your Android device, go to Settings, then Network & Internet, then Wi-Fi.
  3. Tap the gear icon next to your 5GHz network and select Forget.
  4. Connect only to the 2.4GHz SSID.
  5. If available, enable Developer Options and look for Wi-Fi scan throttling or band preferences, though these vary by manufacturer.

Some Android skins, such as Samsung One UI, include a Wi-Fi band preference under Settings > Connections > Wi-Fi > Advanced. If present, select 2.4GHz only.

Disable 5GHz on iPhone/iPad

iOS does not allow users to manually lock Wi-Fi to a specific band. The operating system automatically chooses the best available network.

Step-by-Step iOS Workaround

  1. On your router, create a unique SSID for the 2.4GHz band only.
  2. On your iPhone or iPad, go to Settings > Wi-Fi.
  3. Tap the info icon next to any saved 5GHz network and choose Forget This Network.
  4. Connect to the 2.4GHz-only SSID.

Because iOS aggressively roams between bands, keeping the 5GHz SSID forgotten is the most reliable client-side method. For a permanent solution, disable 5GHz at the router level.

Comparison of Methods

Method Scope Difficulty Best For
Router-level disable Entire network Moderate Households with legacy devices
Windows adapter settings Single PC Easy Office desktops
macOS preferred networks Single Mac Easy Mac users needing 2.4GHz
Android forget 5GHz SSID Single phone Easy Smart home setup
iOS forget 5GHz SSID Single device Easy Apple mobile users

Tips and Best Practices

  • Always separate your SSIDs if you want precise control. Name them clearly, such as Home_2.4GHz and Home_5GHz.
  • Keep router firmware updated to avoid bugs that can re-enable disabled bands after a reboot.
  • Document your changes. If you disable 5GHz for troubleshooting, set a reminder to re-enable it later.
  • Use Ethernet for the initial router configuration to prevent lockout.
  • Test signal strength after disabling 5GHz. You may need to reposition your router or add a range extender.
  • Remember that disabling 5GHz reduces maximum throughput. Only do it when necessary.

Troubleshooting Common Issues

Sometimes after you figure out How to Turn 5ghz Wifi Off?, devices still try to connect to the old band. If that happens, restart the affected device, clear saved networks, or reset network settings. On Windows, running ipconfig /release and ipconfig /renew can force a fresh DHCP lease on the 2.4GHz network. If your router re-enables 5GHz automatically, check for a “Smart Connect” or “Band Steering” feature and disable it, as that feature often overrides manual radio settings.

Frequently Asked Questions

Will disabling 5GHz slow down my internet?

It can reduce peak speeds, especially for devices close to the router, but your actual internet speed depends on your ISP plan. If your plan is under 100 Mbps, 2.4GHz is usually sufficient.

Can I turn 5GHz back on later?

Yes. Simply reverse the steps in this guide. Re-enable the 5GHz radio in your router settings or reconnect to the 5GHz SSID on your devices.

Why does my device keep reconnecting to 5GHz?

Your device may have saved the 5GHz network as preferred. Forget the network entirely and prioritize the 2.4GHz SSID. Also disable any “Smart Connect” feature on your router.

Is it safe to disable 5GHz?

Yes. It is a standard configuration change. Just ensure you do not lose access to your router during the process by keeping an Ethernet connection available.

Do all routers allow disabling 5GHz?

Most modern routers do, but some ISP-provided gateways hide the option. You may need to contact your provider or use bridge mode with a third-party router for full control.

Conclusion

Understanding How to Turn 5ghz Wifi Off? gives you greater control over your home or office network. Whether you disable it at the router for everyone or adjust settings on a single device, the process is straightforward once you know where to look. Start with the method that matches your situation, test thoroughly, and remember that you can always re-enable 5GHz when you need faster speeds or better performance in close range. With separated SSIDs, updated firmware, and a clear plan, managing your Wi-Fi bands becomes simple and stress-free.
