How to Set 5 GHz or 2.4 GHz Frequency Band in Windows 10

Do you know how to set 5 GHz or 2.4 GHz frequency band on wireless adapter in Windows 10? With this setup your device will be able to connect to preferred 5 GHz or 2.4 GHz wireless network all the time.



This is likely what you would like to do if you have both 2.4 GHz and 5 GHz wireless network set up at home (check this out to do it on wireless router here if you need help).

Let's quickly go through the steps below to make the change. Please note you can only do this if your wireless adapter supports both 2.4 GHz and 5 GHz bands.

1) First, log on to Windows 10 as an administrator and right click the Start button and click on the Device Manager.

Note: You will get following prompt if you are not logged on as administrator, and you have read only access as a standard user. Please note that you need administrator access privileges to make this change.

2) Device Manager window will appear, scroll down and click on Network adapters. Here you will find a list of network related adapters, and you can go ahead to click on the network adapter which you would like to change the frequency band.

As you can see here, I clicked on my wireless adapter, Realtex 8822CE Wireless LAN 802.11ac PCI-E NIC, then right click and click on Properties.

3) Immediately the Properties of the wireless adapter will appear, go ahead to click on Advanced tab and locate the Preferred Band. Click on it once you have located it, and there typically you can set it with No Preference, 2.4G First and 5G first options. For my case I selected 5G first as I wanted to connect to 5 GHz network as my preference.
Note: If there is no preferred band option, then look for another option called VHT 2.4G. If it's available, you can change the value to Disable to disable the 2.4 GHz entirely and force your wireless adapter to use only 5 GHz.
