Troubleshoot Missing 5GHz Network on Windows 11: Top 7 Solutions

The 2.4GHz and 5GHz are the most common Wi-Fi bands used by routers. While most computers easily recognize both these bands, some might fail to detect a 5GHz Wi-Fi connection.

As such, if your router’s 5GHz connection is not appearing on your computer, here are some fixes you can try to eliminate the problem for good.

Why Is Windows 11 Not Showing Any 5GHz Wi-Fi Connections?

The 5GHz band offers higher speeds and lets you connect more devices. But sometimes, Windows 11 may fail to detect the 5GHz Wi-Fi connection. This mainly happens due to the following reasons:

1. Your computer might fail to detect the 5GHz band due to driver issues.
2. The problem can appear if your router is not working correctly.
3. An issue with the Transmission Control Protocol and Internet Protocol (or TCP/IP) can also be the prime reason why Windows 11 is unable to recognize the 5GHz band.

Now that you know all the primary culprits behind the issue let’s dive into the working fixes.

1. Make Sure Your Computer Supports the 5GHz Wi-Fi Band

Before getting into advanced troubleshooting, make sure your computer is compatible with the 5GHz connection. As it turns out, if your device doesn’t support the 5GHz band, there’s no chance it will detect it.

To check your computer’s 5GHz bandwidth compatibility, follow the below instructions:

1. Press theWin key to open theStart Menu.
2. In the search bar, typeCommand Prompt and clickRun as administrator in the right pane.
3. Type the following command in the elevated Command Prompt window and press Enter.
   netsh wlan show drivers
4. Scroll down and look for the section named**”Number of** supported bands.”
   
5. If this section shows both 2.4GHz and 5GHz, then it indicates your computer is compatible with the 5GHz band. But if it only shows 2.4GHz, then it means that your device doesn’t support a 5GHz connection.

Another method to confirm your computer’s compatibility is by checking the radio types.

If the radio type shows802.11a 802.11g 802.11n , then your computer is compatible with both 2.4GHz and 5GHz connections. But if it shows802.11g 802.11n or802.11n 802.11g 802.11b as available network modes, then your device only supports the 2.4GHz Wi-Fi band.

2. Restart Your Router
