Introduction

If your video calls keep freezing, your online games lag at the worst possible moment, or your movie buffers right before the climax, your Wi-Fi band might be to blame. Most modern routers broadcast on two different frequencies: 2.4GHz and 5GHz. The 5GHz band offers faster speeds and less interference, but many devices stay stuck on the slower 2.4GHz band by default. If you have been searching for How to Change Wifi to 5g?, this guide will walk you through everything you need to know.

First, a quick clarification: when people say “5g Wi-Fi,” they usually mean the 5GHz wireless band. This is not the same as 5G cellular service from mobile carriers. In this article, “5g” refers to the 5GHz frequency used by Wi-Fi routers.

Switching to 5GHz is not always as simple as flipping one switch. Your router must support it, your devices must be compatible, and you may need to adjust settings on both ends. Below, you will find a complete roadmap, from checking your hardware to configuring specific devices and troubleshooting common problems.

What Is 5GHz Wi-Fi and Why It Matters

Wi-Fi signals travel over radio frequencies. The two most common bands for home networking are 2.4GHz and 5GHz. Think of them as two different roads leading to the internet. The 2.4GHz band is older, more crowded, and travels farther through walls, but it is slower and more prone to interference from microwaves, baby monitors, and neighboring routers. The 5GHz band is newer, offers more channels, and handles data much faster, but its signal does not penetrate walls as well and has a shorter effective range.

When you change Wi-Fi to 5g, you are essentially moving your device from the crowded highway to a faster express lane. This is especially helpful for bandwidth-heavy tasks like 4K streaming, video conferencing, online gaming, and large file transfers. Because fewer household devices use 5GHz, there is typically less congestion, which means more stable connections and lower latency.

That said, 5GHz is not a magic fix for every situation. If your router is in the basement and your bedroom is three floors away, the 5GHz signal might not reach you reliably. In those cases, 2.4GHz may still be the better choice, even if it is slower. The ideal setup usually involves using both bands strategically, which we will cover later in this guide.

2.4GHz vs 5GHz Wi-Fi Comparison

Before diving into the steps, it helps to understand the trade-offs between the two bands. The table below summarizes the key differences so you can decide when to use each one.

Feature 2.4GHz 5GHz
Maximum speed Slower (typically up to 450–600 Mbps) Faster (typically up to 1300 Mbps or more, depending on router)
Range Longer; better at penetrating walls and floors Shorter; weaker through solid obstacles
Interference High; shared with microwaves, Bluetooth, cordless phones, and many routers Lower; fewer household devices use this band
Available channels Fewer non-overlapping channels More non-overlapping channels
Best for Smart home devices, older gadgets, devices far from the router Streaming, gaming, video calls, laptops, phones near the router
Congestion Often crowded in apartments and dense neighborhoods Generally less crowded

As you can see, neither band is universally better. The right choice depends on where your device is located and what you are doing online.

Check If Your Router Supports 5GHz

Before you can change Wi-Fi to 5g, you need to confirm that your router actually broadcasts a 5GHz signal. Not all routers do, especially older models or basic ISP-provided units.

Start by looking at the physical label on your router. If you see terms like “dual-band,” “802.11ac,” “802.11ax,” “Wi-Fi 5,” or “Wi-Fi 6,” there is a good chance your router supports 5GHz. If the label only mentions 802.11n or 2.4GHz, it may be a single-band router.

You can also log into your router’s admin panel to verify. Connect your computer to the router via Ethernet or Wi-Fi, open a web browser, and enter the router’s IP address. Common addresses include 192.168.1.1, 192.168.0.1, or 192.168.1.254. The exact address is usually printed on the router label. Once logged in, look for wireless settings. If you see separate options for 2.4GHz and 5GHz, or a field labeled “Band,” your router supports 5GHz.

If you are renting a router from your internet service provider, you can call customer support and ask whether your model is dual-band. If it is not, you may need to purchase your own router before you can change Wi-Fi to 5g.

Check If Your Devices Support 5GHz

Even if your router supports 5GHz, your phone, laptop, or smart TV must also have a wireless adapter capable of connecting to that band. Most devices made in the last several years support 5GHz, but older hardware often does not.

On a Windows laptop, you can check by opening Device Manager, expanding Network adapters, right-clicking your wireless adapter, and selecting Properties. Look under the Advanced tab for an option related to band or 802.11 mode. If you see options that mention 5GHz or 802.11a/ac/ax, your adapter supports it.

On a Mac, hold the Option key and click the Wi-Fi icon in the menu bar. If you see channel information and your network appears on a channel above 36, you are likely on 5GHz. You can also check System Information under Network > Wi-Fi to see supported PHY modes.

For smartphones and tablets, check the manufacturer’s specifications online. Look for Wi-Fi 4 (802.11n), Wi-Fi 5 (802.11ac), or Wi-Fi 6 (802.11ax) with dual-band support. Devices that only list 802.11b/g/n are typically limited to 2.4GHz.

If your device does not support 5GHz, there is no setting you can change to make it work. You would need to use an external USB Wi-Fi adapter that supports 5GHz, or continue using the 2.4GHz band.

How to Change Wi-Fi to 5GHz on Your Router

The most important step in changing Wi-Fi to 5g happens at the router level. If the router is not configured to broadcast a 5GHz network, your devices will have nothing to connect to. Here is a general step-by-step process that works for most router brands, though exact menu names may vary.

  1. Connect to your router. Plug your computer into the router with an Ethernet cable for the most stable connection, or connect to the existing Wi-Fi network.
  2. Find the router’s IP address. On Windows, open Command Prompt and type ipconfig. Look for the “Default Gateway” address. On Mac, go to System Settings > Network > Wi-Fi > Details > TCP/IP and look for the Router address.
  3. Log into the admin panel. Open a web browser, type the IP address into the address bar, and press Enter. Enter the admin username and password. If you have never changed them, they are often printed on a sticker on the router (common defaults include admin/admin or admin/password).
  4. Navigate to wireless settings. Look for tabs or menus labeled Wireless, Wi-Fi Settings, Wireless Settings, or Advanced Wireless.
  5. Enable the 5GHz band. Find the section for 5GHz or Band Selection. Make sure the 5GHz radio is turned on or enabled.
  6. Set an SSID. You can give the 5GHz network the same name as your 2.4GHz network or a different name. Using the same name allows devices to roam between bands automatically, while a different name (for example, “HomeWiFi-5G”) lets you choose manually.
  7. Choose security settings. Select WPA2-PSK (AES) or WPA3 if your router supports it. Avoid WEP, which is outdated and insecure.
  8. Set a password. Create a strong Wi-Fi password if you have not already.
  9. Save and apply. Click Save, Apply, or OK. The router may reboot, which can take a minute or two.
  10. Reconnect your devices. Once the router restarts, search for the 5GHz network on your phone, laptop, or other device and enter the password.

After completing these steps, you have successfully changed Wi-Fi to 5g at the source. Your devices can now connect to the faster band whenever they are within range.

How to Change Wi-Fi to 5GHz on Windows

Windows does not always have a simple toggle to force a connection to 5GHz, but you can encourage your computer to prefer it. If your router broadcasts separate SSIDs for 2.4GHz and 5GHz, the easiest method is to connect to the 5GHz network by name. Windows will remember that preference and try to reconnect to it automatically.

If your router uses a single SSID for both bands, you can adjust your wireless adapter’s advanced settings to prefer 5GHz:

  1. Press Windows key + X and select Device Manager.
  2. Expand Network adapters.
  3. Right-click your wireless adapter (it may say Wi-Fi, Wireless, or include a brand name like Intel, Realtek, or Qualcomm) and choose Properties.
  4. Go to the Advanced tab.
  5. Look for a property named Preferred Band, Band, 802.11n/ac/ax Mode, or something similar.
  6. Change the value to 5GHz, Prefer 5GHz, or 802.11ac.
  7. Click OK and restart your computer if prompted.

Not all adapters expose this option. If you do not see a band preference setting, your driver may not support it, or Windows may handle band selection automatically based on signal strength.

How to Change Wi-Fi to 5GHz on Mac

macOS generally handles band selection automatically and does not provide a simple user interface to lock the computer to 5GHz. However, you can check which band you are using and influence which network your Mac joins.

To check your current band, hold the Option key and click the Wi-Fi icon in the top menu bar. Look for the channel number. Channels 1 through 14 are typically 2.4GHz, while channels 36 and above are typically 5GHz.

If your router uses separate names for 2.4GHz and 5GHz, simply connect to the 5GHz SSID. macOS will prioritize it in the future. If both bands share the same name, macOS will choose what it considers the best signal, which is often 5GHz when you are close to the router.

For more control, go to System Settings > Network > Wi-Fi and click the details button next to your network. You can review the connection details, though forcing a specific band usually requires router-side settings such as band steering or separate SSIDs.

How to Change Wi-Fi to 5GHz on Android

Android phones vary by manufacturer, and there is no universal “force 5GHz” toggle in standard settings. If your router broadcasts separate SSIDs, the simplest approach is to connect to the 5GHz network by name. Android will remember that choice and reconnect automatically when in range.

To check which band you are using on many Android devices:

  1. Open Settings.
  2. Go to Network & internet or Connections, then Internet or Wi-Fi.
  3. Tap the gear icon next to your connected network.
  4. Look for Frequency band or Network frequency. It should say 5GHz if you are connected to that band.

If you cannot find this information, download a Wi-Fi analyzer app from the Google Play Store. These apps show which frequency your current connection is using and can help you identify nearby 5GHz networks.

Some Android skins include a “Preferred band” or “Wi-Fi frequency band” setting under Developer Options or advanced Wi-Fi settings, but this is not available on every device.

How to Change Wi-Fi to 5GHz on iPhone and iPad

Apple’s iOS does not show the Wi-Fi frequency band directly in the standard Settings app, and there is no toggle to force 5GHz. If your router uses separate network names, simply join the 5GHz SSID. iOS will remember it and prefer it going forward.

If you want to verify which band your iPhone is using, you can use Apple’s free AirPort Utility app:

  1. Download and install AirPort Utility from the App Store.
  2. Open Settings > AirPort Utility and toggle on Wi-Fi Scanner.
  3. Open AirPort Utility and tap Wi-Fi Scan.
  4. Look at the list of nearby networks. Find your router and check the Channel column. Channels above 36 indicate 5GHz.

If both bands share the same SSID, iOS generally steers devices to 5GHz when the signal is strong enough. If you notice your iPhone clinging to 2.4GHz, try moving closer to the router or temporarily disabling the 2.4GHz radio in your router settings to force the connection.

How to Change Wi-Fi to 5GHz on Smart TVs and Game Consoles

Smart TVs, streaming sticks, and game consoles often have more limited Wi-Fi capabilities than phones and laptops. Before trying to change Wi-Fi to 5g on these devices, confirm that the hardware supports it.

Most modern smart TVs and streaming devices (such as Roku Ultra, Apple TV 4K, and Amazon Fire TV Stick 4K) support 5GHz. Older or budget models may be 2.4GHz only. The same goes for game consoles: PlayStation 5 and Xbox Series X/S support 5GHz, while the original PlayStation 4 and Xbox One may be limited to 2.4GHz depending on the model.

To connect these devices to 5GHz:

  1. Open the device’s network settings menu.
  2. Choose Set up internet connection or Network setup.
  3. Select Wi-Fi or Wireless.
  4. If your router broadcasts separate SSIDs, choose the 5GHz network name and enter the password.
  5. If your router uses one SSID for both bands, the device will connect automatically, but there is no guarantee it will pick 5GHz.

If a TV or console only sees the 2.4GHz network, check whether your router has “Smart Connect” or “Band Steering” enabled. These features combine both bands under one name and can sometimes prevent older devices from seeing 5GHz. Disabling Smart Connect and giving each band its own name often solves the problem.

Troubleshooting Common 5GHz Issues

Even after you change Wi-Fi to 5g, you might run into problems. Here are the most common issues and how to fix them.

I cannot see the 5GHz network. First, confirm that your router actually supports 5GHz and that the radio is enabled in the admin panel. Next, make sure your device is 5GHz-compatible. If both are true, check whether the 5GHz SSID is hidden or whether Smart Connect is merging the bands under one name.

The 5GHz signal is weak or drops out. Remember that 5GHz does not travel through walls as well as 2.4GHz. Move your router to a central, elevated location away from large furniture, metal objects, and appliances. If you are far from the router, consider using 2.4GHz for that room or adding a mesh system or access point.

Internet speed is still slow on 5GHz. A fast Wi-Fi band cannot fix a slow internet plan. Run a speed test while standing next to the router on 5GHz. If speeds are still low, try changing the 5GHz channel in your router settings. Channels 36, 40, 44, and 48 are common for domestic use, while channels 149 and above may offer more bandwidth depending on your region. A Wi-Fi analyzer app can show which channels are least congested.

Devices keep switching between bands. If your router uses one SSID for both bands, devices may roam between 2.4GHz and 5GHz based on signal strength. To prevent this, give each band a unique name and manually connect important devices to the 5GHz SSID.

I forgot my router admin password. Most routers have a small reset button on the back. Press and hold it for about 10 seconds to restore factory defaults, then log in with the default credentials printed on the label.

Tips and Best Practices for 5GHz Wi-Fi

Getting the most out of 5GHz requires more than just turning it on. Follow these best practices for a faster, more stable wireless experience.

  • Use separate SSIDs if you want control. Naming your 5GHz network something like “HomeWiFi-5G” lets you manually choose which devices use the fast band. Reserve 2.4GHz for smart bulbs, plugs, and other IoT devices that do not need high speed.
  • Place your router wisely. Put it in a central location, off the floor, and away from thick walls, mirrors, and large appliances. 5GHz signals degrade quickly when blocked.
  • Match the band to the task. Use 5GHz for laptops, phones, gaming consoles, and streaming devices in the same room as the router. Use 2.4GHz for devices in distant rooms or for devices that only need low bandwidth.
  • Keep firmware updated. Router manufacturers release updates that improve wireless performance, security, and compatibility. Check your admin panel for updates every few months.
  • Use WPA2 or WPA3 security. Never leave your Wi-Fi open. WPA3 is the newest standard, but WPA2-AES is still secure and widely supported.
  • Consider a mesh system for large homes. Because 5GHz has limited range, a single router may not cover an entire house. Mesh nodes placed throughout your home can extend 5GHz coverage without the speed loss common with older repeaters.
  • Use Ethernet when possible. For desktop PCs, gaming consoles, and smart TVs near the router, a wired Ethernet connection is always faster and more stable than Wi-Fi, even on 5GHz.

Frequently Asked Questions

Is 5G Wi-Fi the same as 5G cellular?

No. “5G” in cellular refers to the fifth generation of mobile network technology from carriers like Verizon, AT&T, or T-Mobile. In Wi-Fi, “5g” is shorthand for the 5GHz frequency band. They are completely different technologies.

Will changing Wi-Fi to 5g increase my internet speed?

It can improve your local wireless speed and reduce latency, but it cannot exceed the speed of your internet plan. If you pay for 100 Mbps from your ISP, 5GHz Wi-Fi will not magically give you 500 Mbps. However, if your 2.4GHz connection was bottlenecking your plan, moving to 5GHz may let you reach the speeds you are paying for.

Can I use 2.4GHz and 5GHz at the same time?

Yes. Most dual-band routers broadcast both bands simultaneously. Different devices can connect to different bands at the same time. This is ideal for homes with a mix of old and new gadgets.

Why does my 5GHz Wi-Fi not reach other rooms?

5GHz signals have shorter wavelengths and are absorbed more easily by walls, floors, and furniture. If coverage is an issue, try repositioning the router, switching to 2.4GHz for distant rooms, or installing a mesh Wi-Fi system.

Do I need to buy a new router to change Wi-Fi to 5g?

Only if your current router does not support 5GHz. Check the model number or label for “dual-band,” “802.11ac,” “802.11ax,” “Wi-Fi 5,” or “Wi-Fi 6.” If your router is single-band 2.4GHz only, a new router is required.

How do I know which band my device is using?

On Windows, check the network properties or use Command Prompt. On Mac, Option-click the Wi-Fi menu. On Android, look in the network details or use a Wi-Fi analyzer app. On iPhone, use AirPort Utility’s Wi-Fi scanner to check the channel number.

Conclusion

Changing Wi-Fi to 5g is one of the easiest ways to improve your home network performance, but it requires the right hardware and a little configuration. Start by confirming that both your router and your devices support 5GHz. Then, log into your router’s admin panel to enable the 5GHz radio and set up a network name and password. From there, connect your phones, laptops, and other devices to the faster band.

Keep in mind that 5GHz is not always the best choice for every device or every room. Its shorter range means it works best when you are relatively close to the router. For smart home gadgets and devices far from the router, 2.4GHz is often more reliable. By using both bands strategically, you can build a home network that balances speed, range, and stability.

If you run into issues, use the troubleshooting steps in this guide to check your router settings, adjust channel selection, and improve placement. With the right setup, you should notice faster downloads, smoother streaming, and a more responsive connection across your devices.
