问题描述
你的情况
-
您已成功安装Ubuntu。
-
您刚刚下载并启动了Ubuntu Live媒体。最新的LTS(另请参阅HWE)或最新的non-LTS版本是首选。查看当前支持的Ubuntu releases列表。)
-
您将Ubuntu安装升级到软件更新程序为您提供的最新版本。 WiFi工作之前，但现在不在新版本中。
你的问题
-
您的笔记本电脑或台式机无线无法使用。您尝试关闭和打开无线开关，并尝试重新启动多次，但您没有看到任何WiFi接入点。
-
您可以看到您的无线接入点，但无法建立连接。
-
你想分析问题，但你不知道从哪里开始，或者你可以提供什么信息。
这个问题和答案是为人们提供无线脚本，它将提供大多数情况下需要的信息来诊断他们的无线问题。

最佳解决方案
无线信息脚本
收集信息以帮助诊断无线问题的最简单和最全面的方法是运行我们在Ubuntu论坛创建的wireless info script，以收集所有最常见的信息，同时屏蔽所有敏感数据。
使用Ctrl + Alt + T打开终端并运行以下命令：
wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info &&
chmod +x wireless-info &&
./wireless-info
这将在它运行的位置创建文件”wireless-info.txt”，并根据其大小另外创建一个名为”wireless-info.tar.gz”的归档文件。 MAC地址和WPA /WEP密钥等敏感信息会自动屏蔽。
如果无法通过受影响的系统连接到互联网，包括通过有线连接，则必须在连接到互联网的系统和它之间移动文件。 USB棒可能是最简单的方法。
将结果发布到paste.ubuntu.com或pastebin.com上，并在您的问题中链接到此处。
脚本的更多细节：GitHub page。
以下是脚本将收集的信息的示例：

########## wireless info END ############次佳解决方案
我会希望在这个脚本中的一切：
wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info && ./wireless-info
它汇集了我想看到的所有信息，并且在大多数情况下可以纠正任何无线问题。
第三种解决方案
我们需要什么信息？这个：
-
你有什么尝试？当你尝试时发生了什么？
-
你的意思是“不起作用”？指示器小程序似乎显示连接但您无法访问任何网页？指示器小程序被冻结？不存在？您可以从指示器小程序中选择一个连接，但该连接的密码不起作用？
-
你的机器是什么以及你运行的是哪个版本的Ubuntu？
-
它曾经工作过吗？ (即，它工作了一段时间并停止工作？它在Windows下工作，但不在Ubuntu下工作？它在12.04下工作，但不是13.10下工作？)
Ubuntu Wireless Troubleshooting Guide似乎是最新的，所以这可能是一个开始的地方。一些有用的命令：
如果您的无线之前曾在此安装过程中工作过，并且您想对连接进行故障诊断：
-
nm-tool将为您提供网络管理器和任何连接设备的状态报告。 -
rfkill将启用或禁用网络设备。rfkill --list将列出所有可用设备并提供其状态的一些线索。您可能需要run this as root。 -
ifdown和ifup将使网络接口上下。如果您更改了设置，停止并以ifdown wlan0和ifup wlan0开始(以root身份)可能会有所帮助。 -
不确定你的网络接口甚至被称为？试试
ifconfig -a
如果您不确定是否安装了驱动程序，请参阅lshw了解您的无线网卡是否内置，或者lspci(用于PCI卡 – 最近不太可能)或lsusb(用于USB无线设备)。 lshw -C network将显示”network”类中的硬件细节，这正是您想要的。再次，您可能需要run this as root。
