因此，您想购买路由器，但不确定您的Windows 11/10笔记本电脑是否支持2.4 GHz 或 5 GHz WiFi^{(2.4 GHz or 5 GHz WiFi)}。在本文中，我们将向您展示一些简单的步骤，您可以使用这些步骤检查您的笔记本电脑是否支持2.4 或 5 GHz Wi-Fi。

哪个 WiFi 更好，2.4 还是 5 GHz？

如果在完成规定的步骤后您意识到您的计算机同时具有WiFi 2.4和 5 GHz，那么您可能想知道哪个更好。这里没有明显的赢家，因为他们都有自己的优点和缺点。

• 一方面，2.4 GHz覆盖的区域很大，它们的波通常可以穿透墙壁或任何固体物体。
• 另一方面，5 GHz为您提供了大约 1 Gbps的疯狂速度。而且由于支持该频率的设备较少，因此不会像 2.4 GHz^(GHz)那样受到拥塞的影响。

因此，这是个人喜好的问题。如果您想覆盖大面积区域，则 2.4 GHz更好，但如果您想要快速快速的互联网，则5 GHz更好。^(GHz)

如何检查笔记本电脑是否支持 2.4 或 5 GHz WiFi

要检查Windows笔记本电脑是否支持 2.4 或 5 GHz，我们将使用命令提示符^{(Command Prompt)}。

因此，使用WinX 菜单^{(WinX Menu)}打开命令提示符^{(Command Prompt)}，键入以下命令并按Enter。

netsh wlan show drivers

现在，查找Radio types supported。

1. 如果它显示802.11g和802.11n ，那么您的笔记本电脑仅支持 2.4 GHz。
2. 如果它显示802.11n、802.11g和802.11b ，那么您的笔记本电脑仅支持 2.4 GHz。
3. 如果它显示一串包含802.11a或802.11ac的频段，则您的计算机支持5 GHz。因此，它将支持两个频段，因为没有笔记本电脑仅支持 5GHz 频段。

例如，您可以查看图像，这台计算机有802.11n、802.11g和802.11b频段，因此它仅支持 2.4 GHz。

顺便说一句，如果您需要，您可以随时 在 2.4 GHz 和 5 GHz Wi-Fi 频段之间轻松切换^{(switch between 2.4 GHz and 5 GHz Wi-Fi bands)}。

希望这篇文章对您有所帮助。

How to check if Windows laptop supports 2.4 or 5 GHz WiFi

So, you looking to buy a Router bυt are not sure whether your Windows 11/10 laptop supports 2.4 GHz or 5 GHz WiFi. In this article, we are going to show you some simple steps using which you can check if your laptop supports 2.4 or 5 GHz Wi-Fi.

Which WiFi is better, 2.4 or 5 GHz?

If after going through the prescribed steps you realized that your computer has both WiFi 2.4 and 5 GHz then you might want to know which one is better. There is no clear winner here as both of them have their own pros and cons.

• On one hand, 2.4 GHz covers a large area and their wave can penetrate walls or any solid object in general.
• On the other hand, 5 GHz gives you that crazy speed of about 1 Gbps. And since there are fewer devices supporting this frequency, it won’t be affected by congestion, unlike 2.4 GHz.

Therefore, it is a matter of personal preference. If you want to cover a large area then 2.4 GHz is better but 5 GHz is better if you want rapid fast internet.

How to check if laptop supports 2.4 or 5 GHz WiFi

To check if a Windows laptop supports 2.4 or 5 GHz, we are going to use the Command Prompt.

So open Command Prompt using the WinX Menu, type the following command and hit Enter.

netsh wlan show drivers

Now, look for Radio types supported.

1. If it displays 802.11g and 802.11n then your laptop only supports 2.4 GHz.
2. If it displays 802.11n, 802.11g, and 802.11b then your laptop only supports 2.4 GHz.
3. If it displays a string of bands that contains 802.11a or 802.11ac then your computer supports 5 GHz. Therefore, it will support both bands as no laptop supports just the 5GHz band.

As an example, you can check the image, this computer has 802.11n, 802.11g, and 802.11b bands, therefore it only supports 2.4 GHz.

Incidentally, should you need to, you can always easily switch between 2.4 GHz and 5 GHz Wi-Fi bands.

Hopefully, this post will help you.
