These days, the Internet has become necessary for doing just about anything on a computer. So, failing to connect to a Wi-Fi network has got to be one of the most harrowing experiences.

Your computer’s network adapter connects to a Wi-Fi network over a frequency band that it supports. The connection will fail if the wireless device is broadcasting on an unsupported frequency.

However, that’s not always the case. Your computer can still fail to connect to the network even if its adapter supports the Wi-Fi frequency.

There are two Wi-Fi radio bands: 5GHz and 2.4GHz which most modern computers support.

5GHz is the newer Wi-Fi version that maximizes short-range connection to boost speed. Meanwhile, the 2.4Ghz version provides coverage at a longer range.

However, it doesn’t offer the same performance and speed that comes with the 5GHz band.

You’re probably reading this article because your Windows 10 or Windows 11 system can’t seem to detect a 5GHz Wi-Fi connection.

We’ll deal with this issue and show you how to get Windows 10 to recognize a 5GHz Wi-Fi network.

Also, if you’re asking questions like, “Why is the Wi-Fi not showing up in Windows 11?” and “Why doesn’t Windows 11 recognize a 5ghz Wi-Fi?” this article is for you.

Why is a computer not showing a 5GHz Wi-Fi connection?

As we mentioned, your network adapter has to support the Wi-Fi version of the wireless device. So, the simple cause of the issue is unsupported Wi-Fi.

However,  things are not always simple.

Other issues, such as wrong settings and configurations and driver problems, could also trigger the problem.

What’s more, if your router is configured to not support 5GHz, your Windows 10 or Windows 11 computer won’t detect it over the 5GHz spectrum.

The 5GHz frequency only tends to short-range needs. So, another reason that your system might not recognize the network is that it’s far away from the Wi-Fi router.

PRO TIP

For optimal network adapter performance and support for necessary Wi-Fi standards, consider using Auslogics Driver Updater. This tool scans your system for outdated or incompatible drivers, ensuring that all your hardware, including your network adapter, runs with the most recent and stable drivers.

With up-to-date drivers, you can significantly reduce connectivity issues and improve the overall speed and reliability of your internet connection.

Do your devices support 5GHz Wi-Fi?

Before you start working on making your computer recognize a 5GHz Wi-Fi, you have to confirm that your network adapter and router support the band.

You can do that for your system by going through Command Prompt. Follow these steps:

  • Launch the Run dialog box by tapping the Windows + R keyboard buttons together.
  • After the Run dialog window appears, type “CMD” (no quotes) and press the CTRL, Shift, and Enter keys together to launch Command Prompt as an administrator.
  • Select Yes once you see the User Account Control pop-up.
  • After the Command Prompt opens in admin mode, type netsh wlan show drivers and tap Enter.
  • You’ll now see your network adapter’s Wi-Fi version and drivers.

Why doesn’t Windows 11 recognize a 5ghz Wi-Fi?

If you only see 802.11g and 802.11b in the “Radio types supported” section, your adapter only supports 2.4Ghz

802.11a 802.11g 802.11n means your adapter supports 2.4GHz and 5GHz.

In some cases, you’ll also see the 802.11ac and 802.11ax radio types. They also support 5GHz.

You can also check if your computer supports 5GHz by going through the network adapter’s Properties dialog. Here’s how:

  • In the taskbar, right-click on the Start button or tap Windows logo + X.
  • After the Power User menu appears, select Device Manager.
  • When the Device Manager shows up, expand the Network Adapters category. Click on the arrow beside Network Adapters.
  • Next, right-click on your wireless adapter and select Properties.

How to check if a computer supports 5GHz WiFi?

Добрый день!

После большого весеннего обновления Windows 10 появилась одна неприятная проблема. Дело в том, что после выключения или перезагрузки компьютера система перестает видеть WiFi на частоте 5 GHz, одновременно с этим проблем с 2.4 GHz нет. Если вручную перезапустить адаптер, то 5 GHz начинает обнаруживаться и компьютер к ней подключается. В редких случаях даже если 5 GHz сеть обнаруживается, подключение не происходит. На всех других домашних устройствах — это несколько телефонов, MacBook Air, пару планшетов — проблем с 5 GHz нет.

Конфигурация:

  • адаптер WiFi — Qualcomm Atheros AR946x (интегрированный, материнская плата ASUS Z87-Pro);
  • версия ОС — официальная Windows 10 Pro 1709 (сборка 16299.64);

Что делал:

  • для адаптера WiFi откатывался к драйверам по умолчанию;
  • устанавливал до 10 различных версий драйвера для адаптера WiFi, включая версии для Win8 и Win7;
  • сбрасывал настройки сети;
  • с тех пор как появилась проблема, я сменил роутер с ASUS RT-N66U на ASUS RT-AC66U;

В интернет решения проблемы я за долгое время так и не нашел, причем как в англоязычном сегменте, так и в русскоязычном. Полгода назад создал тикет в Центре отзывов Microsoft, ответа до сих пор нет. Экспериментировать и покупать другие адаптеры WiFi (USB или PCI-E) не хочу, так как дорого и нет гарантии, что проблема не будет воспроизведена на новом устройстве.
