How to Change the Bandwidth of the 2.4 GHz or 5 GHz Wi-Fi Band
Bandwidth, but why do you have to change the WiFi band? You will get better internet speeds if your modem supports 5 GHz and your system adapter does.
However, the computer can sometimes not detect the 5 GHz band and uses 2.4 GHz automatically.
That’s why you have to force it to use a better frequency. First, let’s see if your computer supports that bandwidth.
Check supported bands
Step 1: Go to the Start menu, type cmd, and then run it.
Step 2: Enter the following command and press Enter.
netsh WLAN show drivers
Step 3: Now, you can see the supported bands.
- 802.11g and 802.11n mean your system only supports 2.4 GHz.
- 802.11g, 802.11n, and 802.11b mean your system only supports 2.4 GHz.
- If multiple bands, including 802.11a or 802.11ac, are shown, your system supports 2.4 and 5 GHz bands.
Bandwidth change between 2.4 GHz and 5 GHz
Step 1: Right-click on the Start menu to launch the WinX menu.
Step 2: Select Device Manager.
Step 3: Click on Network Adapters.
Step 4: Right-click on your WiFi adapter and click Properties.
Step 5: Click on the Advanced tab.
Step 6: In the Property section, click Band or Preferred Band.
Step 7: Now, select the 5 GHz option in the Value section.
Step 8: Click OK.
This method is straightforward, but it helps you have a better internet speed. Of course, miracles will not happen, and your internet speed will increase, but you will have a more stable and suitable band for WiFi.
Of course, there are different ways to ensure the right internet speed. One of these ways is to change the WiFi bandwidth. This tutorial has prepared a 2.4 GHz or 5 GHz WiFi bandwidth switch in Windows 10 for you.
FAQ
What’s the difference between 2.4 GHz and 5 GHz bands?
The 2.4 GHz band offers better range and penetration through walls but slower speeds; the 5 GHz band provides higher speeds but shorter range and less wall-penetration.
How do I force a device to use 5 GHz instead of 2.4 GHz on Windows?
Open Device Manager → Network adapters → your Wi-Fi adapter → Properties → Advanced tab → look for “Preferred band” (or similar) and set it to “Prefer 5GHz”.
How do I split or change the bands on my router so I can pick 2.4 GHz or 5 GHz manually?
Log into your router’s web interface → go to Wireless/Advanced → disable band-steering or “Smart Connect”, enable separate SSIDs for 2.4 GHz and 5 GHz, and you’ll then see each band listed so devices can choose.
