Не подключается 5g wifi к компу windows 10

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.

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.

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.

If your computer doesn’t have support for 5GHz, you’ll have to either upgrade your network adapter or go for a 5GHz-supported external USB Wi-Fi adapter.

However, if your PC supports 5GHz, you have to check your router to confirm if it supports the band.

The information you need should be in your router’s manual or the device’s box.

You can also check for details about the router on the manufacturer’s website to confirm if it supports 5GHz.

How to Force Windows to Use 5GHz Wi-Fi

Conclusion

If resetting your computer doesn’t resolve the problem, your network adapter might be faulty. You can either change it or use an external USB Wi-Fi device.

Сейчас на рынке предлагается большой выбор двухдиапазонных Wi-Fi роутеров, которые могут транслировать Wi-Fi сеть на частотах 2.4 ГГц и 5 ГГц. Однако далеко не все устройства могут видеть и подключаться к Wi-Fi сети, работающей на частоте 5 GHz. Разберемся со случаем, когда устройство с Windows 10 не видит такую сеть.

Преимущества использования Wi-Fi сети с частотой 5 GHz

В чем основные преимущества Wi-Fi сети, работающей на частоте 5 GHz? Эта частота менее загружена и количество шумов/помех на ней будет меньше (это преимущество особо актуально для жителей многоэтажек, когда на частоте 2,4 Ггц работает огромное количество соседских роутеров, телефонов и микроволновок). Также при работе на этой частоте можно достигнуть более высокой пропускной способности и поддерживаются 23 отдельных каналов передачи (против трех каналов у 2,4 ГГц сети). Недостаток – меньшая зона покрытия в сравнении с частотой 2,4.

Как узнать, поддерживает ли ваше устройство сети Wi-Fi 5 ГГц

Поддерживает ли ваш компьютер, ноутбук или планшет работу с Wi-Fi сетями на частоте 5 ГГц или нет зависит от модели беспроводного адаптера, установленного в нем. Можно найти вашу модель адаптера на сайте производителя и ознакомится с его характеристиками (часто в названии таких адаптеров указна фраза Dual Band). Но есть способ проще.

Проверить поддержку различных беспроводных стандартнов драйвером Wi-Fi адаптера в Windows можно следующим образом:

1. Запустите командную строку с правами администратора
2. Выполните команду:
   netsh wlan show drivers
3. Посмотрите, что указано в разделе Radio types supported

Картинка с сайта: winitpro.ru

Это список беспроводных стандартно, которые поддерживаются данный драйвером.

Адаптеры с поддержкой стандартов 802.11a, 802.11h, 802.11j и 802.11n могут работать как на частоте 5 ГГц, так и на 2.4 ГГц.

Примечание. Один нюанс касательно стандарта 802.11n. В нем определена поддержка стандарта 5 ГГц, но работать в двух диапазонах умеют далеко не все сетевые адаптеры (дело в том, что есть два стандартна 802.11n от 2006 года и 802.11n Dual Band от 2009).

Стандарт 802.11ac означает, что устройство может работать только на частоте 5 ГГц.

Примеры.

• Допустим в списке поддерживаемых стандартов указана поддержка 802.11b и 802.11g, это значит данный драйвер поддерживает только Wi-Fi сети на частоте 2.4 ГГц.
• Если указано, что адаптер поддерживает 802.11a, 802.11g и 802.11n, значит поддерживаются оба частотных диапазона.

Таким образом, если в списке поддерживаемых стандартов нет строк, указывающих на наличие поддержки нового диапазона, стоит проверить на сайте производителя сетевой карты, поддерживает ли она новые стандарты. В некоторых случаях для корректной работы на частоте 5 ГГц достаточно установить последнюю версию драйверу, скачанную с сайта производителя.

В том случае, если указано, что драйвер поддерживает 802.11ac/802.11n, но Windows не видит Wi-Fi сеть, работающую на частоте 5 ГГц, откройте свойства драйвера беспроводного интерфейса и в его настройках проверьте не выбран ли вручную только один диапазон.

К примеру, на Surface Pro 3 с адаптером Marvell AVASTAR Wireless-AC Network Controller, видно, что на вкладке Advanced в свойстве Band можно выбрать в каком режиме должен работать адаптер (Auto/2.4 GHz Only/ 5 GHz Only). Измените режим на Авто.

Windows 10 перестает видеть 5 ГГЦ Wi-Fi после обновления

Некоторые пользователю жалуются, что после выполнения апгрейда Windows 10, система перестает видеть Wi-Fi сети с частотой 5 ГГц. Как правило проблема решается путем ручного скачивания и установки последней версии драйвера для вашего беспроводного адаптера с сайта производителя. Автоматическое обновление драйверов при этом желательно отключить.

Если адаптер не поддерживает сеть 5 ГГЦ

Если ваш сетевой адаптер не поддерживает работу с Wi-Fi сетями на частоте 5 ГГц, просто используйте обычную сеть 2.4 ГГц. Если уж очень хочется работать на новой частоте, можно приобрести внешний USB Wi-Fi адаптер с поддержкой частоты 5 ГГц (выше мы описали требования к стандартам 802.11, которым должно соответствовать устройство).
