更新或重新安装后，您的Windows计算机上的(Windows)Wi-Fi 信号强度是否较低(low Wi-Fi signal strength)？这篇文章讨论了一些解决此问题并克服计算机信号强度低的方法。
随着我们的认知革命，我们的设备连接方式也发生了变化。大多数设备使用一种或其他无线技术与其他设备连接。所有无线技术对范围和信号强度都有某种限制。当您从计算机连接到 Wi-Fi 网络时，您可能会遇到类似的情况。当您来自更新或重新安装时，通常会发生这种情况。继续阅读以找出导致 Wi-Fi 信号低的原因和可能的解决方案。
Windows 11/10 上的 Wi-Fi(Wi-Fi)信号强度低
只需查看Wi-Fi(Wi-Fi)图标中的信号条即可识别低Wi-Fi信号强度。(Wi-Fi)或通过测量Wi-Fi强度。这个问题的范围很广，可能有数百种可能性。在这篇文章中，我们试图涵盖可能对大多数人有帮助的最常见的情况。
- 运行网络适配器疑难解答
- 使用设备管理器
- 更改 WiFi 漫游灵敏度
- 无线网络范围。
让我们详细看看这些建议。
1]运行网络适配器疑难解答(Run Network Adapter Troubleshooter)
如果几天前或在更新或重新安装之前范围和信号是完美的，那么可能某些配置已更改。更新随附的最新配置与笔记本电脑随附的配置不一致。克服这种情况的最简单和最简单的方法是运行Network Adapter Troubleshooter。
要开始故障排除，请右键单击系统托盘中的 Wi-Fi 图标，然后选择故障排除(Troubleshoot)。运行疑难解答程序可能需要一段时间，一旦完成，它将向您显示网络适配器的所有问题。它还将在后台修复它们，但同样存在一些需要手动操作的问题。如果疑难解答程序无法识别并解决您的问题，那么您必须遵循更有针对性的解决方案。

2]使用设备管理器
要解决所有与硬件相关的问题，我们需要借助设备管理器。(Device Manager. )打开设备管理器，在网络适配器(Network Adapters)下找到您的 Wi-Fi 适配器。右键单击它，然后打开Properties。现在在驱动程序选项卡下，您可以看到与驱动程序相关的所有操作。您可以尝试更新(update)或回滚(rollback)驱动程序。或者您可以禁用并重新启用设备(disable and re-enable the device)以查看您的问题是否已解决。
如果没有任何帮助，那么您需要深入研究高级设置。从这一点开始，理解这些术语及其配置也变得有些复杂。您可以尝试在线搜索您的 Wi-Fi 适配器并尝试按照其中提到的说明进行操作。
例如，RT3290 无线适配器(RT3290 Wireless Adapter)的一个特殊修复是更改高级选项卡中的灵敏度选项。或者另一个修复方法是将默认天线类型更改为Auxiliary。这些是您必须在计算机上尝试的一些内容。您可以搜索互联网，看看其他遇到同样问题的人做了什么。在对系统进行任何更改之前，请(Make)确保您已创建系统还原点。
3]更改WiFi漫游灵敏度
如果您希望改善Windows PC 上的 Wi-Fi 接收和性能，您可能需要考虑更改 WiFi Roaming Sensitivity 或 Aggressiveness(changing the WiFi Roaming Sensitivity or Aggressiveness)。漫游灵敏度(Sensitivity)是您的设备选择并切换到最近的可用接入点的速率，从而提供更好的信号。它基于信号强度和质量，而不是与WiFi点的距离。
4] Wi-Fi范围
这是一种可能，这与您的硬件或驱动程序无关，而是您的计算机相对于 Wi-Fi 路由器的位置。您的实际位置可能是信号强度低的问题。也许您想阅读我们关于如何提高 WiFi 速度和信号强度和覆盖区域(increase WiFi Speed and Signal strength and coverage area)的帖子。

Low Wi-Fi signal strength on Windows 11/10.
Do you face low Wi-Fi signal strength on your Windows computer after an update or re-installation? This post talks about a few methods to fix this issue and overcome low signal strength on your computer.
With our cognitive revolution, the way our devices connect has evolved too. Most of the devices use one or other wireless technology to connect with other devices. All wireless tech has some sort of limitation on the range and signal strength. And you might have faced something similar while connecting to a Wi-Fi network from your computer. This usually happens when you are coming from an update or reinstallation. Read on to find out what is causing low Wi-Fi signal and possible solutions.
Low Wi-Fi signal strength on Windows 11/10
Low Wi-Fi signal strength can be identified by simply having a look at the signal bars in the Wi-Fi icon. or by measuring the Wi-Fi strength. This problem has a very wide scope, there could be hundreds of possibilities. In this post, we’ve tried to cover the most generic situations that might help most of the people.
- Run Network Adapter Troubleshooter
- Use the Device Manager
- Change WiFi Roaming Sensitivity
- Wi-Fi Range.
Let us take a look at the suggestions in detail.
1] Run Network Adapter Troubleshooter
If the range and signal were perfect a few days ago or before an update or reinstall, then probably some configuration has been changed. The latest configuration that came with the update is not aligned with the config that came with your laptop. The easiest and simplest way to overcome this situation is running Network Adapter Troubleshooter.
To start troubleshooting, right-click the Wi-Fi icon from the system tray and select Troubleshoot problems. It might take a while to run the troubleshooter and once it is done, it will display you all the problems with your network adapter. It will also fix them in the background but again there are some problems that will require manual action. If the troubleshooter was not able to identify and fix your problem, then you must follow a more targeted solution.

2] Use the Device Manager
To solve all hardware related issues, we need to take the help of Device Manager. Open the device manager, and under Network Adapters find your Wi-Fi adapter. Right-click it and then open Properties. Now under the driver tab, you can see all actions related to drivers. You can try to update or rollback the driver. Or you can disable and re-enable the device to see if your problem has been solved.
If nothing helps, then you need to dig into advanced settings. From this point onwards, it gets a little complex to understand the terms and their configuration as well. You can try searching online for your Wi-Fi adapter and try to follow the instructions mentioned there.
For example, a peculiar fix for RT3290 Wireless Adapter is changing the sensibility option in the advanced tab. Or another fix is changing the default antenna type to Auxiliary. These are some of the things that you will have to try on your computer. You can search the internet and see what other people did who faced the same issue. Make sure you have created a system restore point, before making any changes to your system.
3] Change WiFi Roaming Sensitivity
If you wish to improve the Wi-Fi reception and performance on your Windows PC, you may want to consider changing the WiFi Roaming Sensitivity or Aggressiveness. Roaming Sensitivity is the rate at which your device selects and switches to the nearest available point of access, offering a better signal. It is based on the signal strength and quality – and not on the distance to the WiFi point.
4] Wi-Fi Range
This is one possibility that this has nothing to do with your hardware or drivers but rather the position of your computer with respect to the Wi-Fi router. Your physical location might be an issue for low signal strength. Maybe you want to read our post on how to increase WiFi Speed and Signal strength and coverage area.
