Trusty Tahr上的英特尔无线Wifi Link 5100无法正常工作
嗨，我是linux新手并使用trustry tahr。 早在Windows上，wifi曾经正常工作，但最近当我切换到ubuntu 14.04时，即使显示可用网络列表，它也无法连接到任何网络。 我在这个网站上发布了很多答案，但是没有任何效果。 我发布了一些命令的输出。 提前致谢。

这更像是对你的问题的一般性回答，并不自称是一个上师。 我正在运行14.04LTS，从输出中可以看出硬件是由Ubuntu看到的。 我在网络上发现的是，任何使用MAC地址的安全机制都没有真正起作用，我怀疑我的mac地址没有传输到路由器。 当我有更多时间时，我需要进一步研究这个问题。
我在其他安全性之上使用mac地址过滤。 在认为是驱动程序等和OEM支持问题后，我通过删除所有安全性（请参阅下面的注释）并尝试连接来解决问题。 幸运的是它确实如此，因此以更兼容的方式保护网络。
请注意 ，我的方法是计算风险 。 我的互联网调制解调器仍然有’防火墙到位，我的笔记本电脑没有任何文件共享，我的路由器（管理员）受密码保护，但请记住，您的路由器可以在那时访问。
我怀疑我遇到的问题是使用相对较旧的路由器，如上所述，传输mac地址。
我希望这可以帮助您导航解决方案。 问候
