Switch Between 2.4 GHz and 5 GHz Wi-Fi Bands in Windows 11
Most modern Wi-Fi routers support 2.4 GHz and 5 GHz Wi-Fi bands. The 2.4 GHz band generally offers better range and can pass through walls more effectively, while the 5 GHz band usually provides faster speeds over shorter distances and may experience less interference from older wireless devices.
Windows 11 lets you adjust your wireless adapter’s preferred band on supported computers. This setting can help your PC favor a particular Wi-Fi band, but it doesn’t guarantee that Windows will connect to it.
Your router, wireless adapter, driver, and network configuration all play a role.
In this guide, you’ll learn how to switch between 2.4 GHz and 5 GHz Wi-Fi bands in Windows 11
Switch Between 2.4 GHz and 5 GHz Wi-Fi Bands in Windows 11
To switch between 2.4 GHz and 5 GHz Wi-Fi bands in Windows 11, open Device Manager, expand Network adapters, open your wireless adapter’s Properties, and look for a Preferred Band option under Advanced. If your adapter supports this setting, select the preferred band, click OK, and reconnect to Wi-Fi.
If the option isn’t available, you may need to use separate Wi-Fi network names or check your router settings.
Step 1: Check Whether Your Wi-Fi Adapter Supports Both Bands
Before changing any settings, check whether your computer’s wireless adapter supports both 2.4 GHz and 5 GHz Wi-Fi. Not every adapter supports both bands, particularly on older computers.
Press Windows + I to open Settings. Select Network & internet, then choose Wi-Fi. Make sure Wi-Fi is turned on and your computer can see nearby wireless networks.
Next, press Windows + X and select Device Manager. Find Network adapters and click the arrow beside it to expand the list.
Look for your wireless adapter. Its name may include terms such as Intel Wireless, Realtek Wireless, Qualcomm, MediaTek, or Wi-Fi. Write down the adapter’s name so you can identify its specifications if needed.
You can also check the supported radio types using Command Prompt. Open the Start menu, type Command Prompt, and launch it. Enter this command and press Enter:
netsh wlan show drivers
Look for the Radio types supported section. The listed standards can help you understand your adapter’s capabilities, although the radio types alone don’t always tell you which frequency bands are enabled by your current driver.
If you’re unsure, check the adapter manufacturer’s specifications or your computer manufacturer’s support page.
Step 2: Open Your Wireless Adapter’s Advanced Settings
Once you’ve confirmed that your wireless adapter supports the band you want, you can check its configuration options.
Open Device Manager by pressing Windows + X and selecting it from the menu. Expand Network adapters and find your wireless adapter.
Right-click the adapter’s name and select Properties. A new window will open with several tabs, including General, Advanced, Driver, Details, and Power Management. The available tabs can vary depending on your hardware.
Select the Advanced tab. You’ll see a list of properties on the left and their corresponding values on the right.
Look for a setting named Preferred Band, Band Preference, or something similar. The exact name depends on your wireless adapter and driver.
If you find the setting, continue to the next step. If you don’t see it, don’t assume your Wi-Fi is broken.
Some adapters don’t expose a band preference setting in Windows, and others use different options to control wireless behavior.
Step 3: Switch to the 5 GHz Wi-Fi Band
If your wireless adapter offers a Preferred Band setting, you can use it to tell Windows to favor 5 GHz Wi-Fi when the network and adapter support it.
In the Advanced tab of your wireless adapter’s Properties window, select Preferred Band from the property list. Open the Value drop-down menu and look for an option such as Prefer 5 GHz band.
Select that option and click OK to save the change. If Windows doesn’t disconnect automatically, disconnect from your Wi-Fi network and reconnect. You can also turn Wi-Fi off and back on through Settings > Network & internet > Wi-Fi.
Keep in mind that choosing 5 GHz doesn’t force your computer to use that band in every situation. If the 5 GHz network isn’t available, is too weak, or isn’t supported by the router’s configuration, your computer may connect through 2.4 GHz instead.
For the best results, use this setting when your computer is relatively close to the router and you want to prioritize speed over range.
Step 4: Switch to the 2.4 GHz Wi-Fi Band
If your computer is far from the router or the connection keeps dropping through walls, 2.4 GHz may be a better choice.
Return to Device Manager > Network adapters. Right-click your wireless adapter, select Properties, and open the Advanced tab.
Select Preferred Band or the equivalent setting. In the Value drop-down menu, choose Prefer 2.4 GHz band, if available.
Click OK to apply the setting. Disconnect from your wireless network and reconnect so your adapter can establish a fresh connection.
The 2.4 GHz band generally offers better coverage across longer distances, but it can be slower in crowded areas because many nearby networks and household devices use the same frequency range.
If you don’t see an option to prefer 2.4 GHz, your adapter driver may not provide manual band selection.
In that case, check the router’s Wi-Fi settings or see whether it offers separate network names for each band.
Step 5: Check Whether You’re Connected to 2.4 GHz or 5 GHz
After changing your preferred band, verify which frequency your computer is actually using. This is important because the preferred band setting is a preference, not a guarantee.
Open Settings > Network & internet > Wi-Fi and select your connected network’s properties. Look for the Network band or Network frequency information, if Windows displays it.
You can also use Command Prompt. Open the Start menu, search for Command Prompt, and run this command:
netsh wlan show interfaces
Find the connected Wi-Fi interface and look for the Channel field. On many routers, channels 1 through 14 are associated with 2.4 GHz, while channels above that range are commonly used for 5 GHz or other supported bands. Channel allocations vary by country and Wi-Fi standard, so use this as a clue rather than a definitive rule.
If your Windows version or driver doesn’t show the frequency directly, check your router’s connected-device page. Many routers display the band each connected device is using.
If the PC still connects to the other band, continue with the next step.
Step 6: Use Separate Wi-Fi Network Names if Available
Some routers combine 2.4 GHz and 5 GHz under one Wi-Fi name. This is often called band steering or a combined-band network. The router decides which band to offer to your device, so Windows may not give you a direct way to select one.
If your router supports separate network names, you may be able to give each band a different name, such as HomeWiFi_2.4 and HomeWiFi_5. The exact process depends on your router.
To check, open your router’s management app or its administration page, then sign in using the router credentials. Find the Wireless, Wi-Fi, or Wireless Settings section. If the router allows separate names for the two bands, configure them according to the manufacturer’s instructions.
Save the changes, then open Windows 11 Wi-Fi settings and connect to the network name for your preferred band.
Changing router settings affects other devices in your home, so check the manufacturer’s guidance before making changes. If you rent your router from your internet provider, some settings may be locked or managed remotely.
Step 7: Update Your Wi-Fi Driver if the Band Option Is Missing
If the Preferred Band setting is missing or the Wi-Fi connection behaves incorrectly, updating the wireless driver may help.
Open Device Manager, expand Network adapters, right-click your wireless adapter, and select Update driver. Choose Search automatically for drivers and follow the on-screen instructions.
Windows may not find the latest driver. If that happens, visit your PC manufacturer’s official support website and search for your exact computer model. Download the recommended wireless LAN driver for Windows 11, if one is available.
Install the driver and restart your computer if prompted. Then return to the adapter’s Properties window and check the Advanced tab again.
Avoid downloading drivers from unfamiliar websites. If the option remains missing after updating, your adapter may not support manual band selection through Windows. You can still use separate router network names when your router supports them.
Step 8: Choose the Best Band for Your Situation
The best Wi-Fi band depends on where you use your computer and what you do online.
Choose 2.4 GHz when you need a connection across a longer distance or through several walls. It’s often useful for a PC in a distant bedroom or an area where 5 GHz signals are weak.
Choose 5 GHz when your PC is near the router, and you want higher potential speeds for video calls, streaming, large downloads, or online gaming. Actual performance depends on your router, internet connection, wireless interference, and adapter capabilities.
If both bands provide a strong, reliable connection, you may not need to change anything. Your router’s automatic band selection may already be working well.
FAQs
1. Can I force Windows 11 to use only 5 GHz Wi-Fi?
Not on every computer. Some wireless adapters offer a Preferred Band setting, but it generally prioritizes a band rather than guaranteeing it. Connecting to a separate 5 GHz network name, if your router provides one, is often the clearest way to choose.
2. Why is the Preferred Band option missing?
The setting depends on your wireless adapter and driver. Some adapters don’t expose manual band selection in Windows. Updating the driver may help, but if the option remains unavailable, check your router’s Wi-Fi settings.
3. Is 5 GHz Wi-Fi always faster than 2.4 GHz?
No. 5 GHz can provide higher speeds at shorter distances, but a weak 5 GHz signal may perform worse than a strong 2.4 GHz connection. Router capabilities, interference, and your internet plan also affect speed.
4. Can I use 2.4 GHz and 5 GHz at the same time?
Your router can broadcast both bands simultaneously, but a typical single Wi-Fi adapter connection uses one band at a time for a given network connection. Your computer can switch bands when the network and adapter allow it.
5. Does switching Wi-Fi bands change my internet plan or speed limit?
No. Switching bands doesn’t change your internet plan. It may improve the wireless connection between your computer and router, but your actual internet speed also depends on your service plan, router, network congestion, and other factors.
