无法连接到WiFi – 英特尔公司无线3160
我最近买了一台新笔记本电脑，自14.04开始拒绝工作，12.04有点过时我安装了Ubuntu 15.04 Beta 2.无论如何，我一直在环顾四周，找不到连接wifi的方法。 它试图连接一段时间，但过了一会儿就放弃了。 以太网工作和BT Hub 1工作，但我不能再尝试使用该集线器。 Hub 2和3不起作用。 我尝试按照本指南进行操作，但它仍然存在同样的问题。 我也在某些时候运行了一些类型的脚本。 也许这对某人来说意味着什么？ ：

要解决此问题，需要粘贴sudo mv /lib/firmware/iwlwifi-3160-12.ucode /lib/firmware/iwlwifi-3160-10.ucode 。 除了重新启动之外，不确定是否还需要其他任何东西。
禁用蓝牙并重启。 这对我有用。 （Intel Wireless 3160（rev 93），内核3.19.0-18，Linux Mint 17.1）
我通过启动开始菜单并输入“bluetooth”来禁用蓝牙。 然后出现蓝牙设置程序。
这个： sudo mv /lib/firmware/iwlwifi-3160-12.ucode /lib/firmware/iwlwifi-3160-10.ucode对我来说没有任何影响。 （并且没有使用15而不是10作为评论建议。）
这是一个关于一个显然是问题根源的错误的问题（至少在我的情况下）：
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1442411
[解决方法]
蓝牙启动已关闭。 如果计算机在蓝牙打开的情况下启动，即使您首先关闭蓝牙，wifi也无法正常工作。 需要重启。
现在出现下一个问题：暂停后如何使蓝牙保持禁用状态？ 这是一个关于它的问题，但它已被关闭太本地化： 如何设置蓝牙在暂停后保持禁用？ – 我认为它不再太局部化了。 …我现在正在测试这个： http ： //ubuntuforums.org/showthread.php？t = 1387211＆p = 9155208＃post9155208 – 编辑：它工作正常，如此:(这不完全是他们在论坛 – 看起来好像我不得不改变它，并在恢复后block不unblock ）

与Ubuntu 14.04和内核3.19.5有同样的问题（我知道，不支持……不幸的是，我可以调整psmouse / synaptics模块以与我的Thinkpad T450上的Trackpoint按钮配合使用的唯一内核 – 请参阅https：// bug .launchpad.net / ubuntu / + source / linux / + bug / 1414930 ）。
我在/ lib / modules下有两个固件文件：iwlwifi-7265D-10.ucode和iwlwifi-7265D-12.ucode）。 “lshw -c network”显示已加载固件= 25.16.12.0，但连接到WiFi无法使用“身份validation超时”。
删除“/lib/modules/iwlwifi-7265D-10.ucode”并将“/lib/modules/iwlwifi-7265D-12.ucode”复制到/lib/modules/iwlwifi-7265D-10.ucode后，它再次开始工作！ 很奇怪….
我更新到15.04并检测到同样的问题。
禁用和重新启用wifi设备为我恢复了wifi。
基本上：
sudo ifconfig wlan0 down sudo ifconfig wlan0 up
所提到的解决方案都不适合我。 幸运的是，我已经修复了我的Lenovo T440p笔记本电脑中的wifi问题，只需将我的linux内核升级到4.x，如下面的post所述 – 安装Linux内核4.0.3
