Ubuntu Intel无线3160 AC不工作/慢/断开/不稳定
Ubuntu Intel无线3160 AC不工作/慢/断开/不稳定
提问于 2014-10-23 12:40:35
我刚买了一个带有英特尔无线3160 a模块的东芝l50-b-1q0。
我安装了ubuntu12.04(听说14个更糟)，并尝试了不同的内核: 3.12rc4、3.11、3.13.2、3.17。但我总是有同样的问题。wifi连接要么是慢的，要么是一直断开，但结果是它无法使用。我也尝试使用iwlwifi从支持版本3.16.1和3.13.2-1。总是同样的问题。我还尝试了使用固件iwlwifi-3160-ucode-9，iwlwifi-3160-ucode-8，iwlwifi-3160-ucode-7内核3.11，3.13.2，3.12 rc4。不走运。我也尝试改用wicd，而不是网络管理器，但问题仍然是一样的。
目前我不知道该做什么，这是非常令人沮丧的。我不得不说，我有类似的问题，一个全新的惠普15-n234sl与Realtek 8188 hp无线模块。我认为问题是Realtek芯片，我把它换成了东芝，因为它有英特尔的无线模块，应该更好。我开始认为Ubuntu有一个新的无线模块的问题，但是没有人知道或理解它。
如果你有什么建议，请帮帮我。
目前，modinfo iwlwifi返回：

我有个类似的问题。我从这里下载了固件：http://wireless.kernel.org/en/users/Drivers/iwlwifi
并将.ucode文件复制到/lib/固件中。重新启动后一切正常。我已经安装了linux固件和非免费包，但我认为它们可能有旧版本的固件。
不管怎样，我希望这对有类似问题的人有帮助。

尝试关闭蓝牙(例如，使用rfkill )。
在从14.10升级到15.04之后，我也遇到了类似的问题。我有一个碳X1，但它也使用iwlwifi。我用rfkill关掉蓝牙解决了这个问题。iwlwifi驱动程序的页面显示，同时运行wifi和蓝牙是很困难的。我注意到脚本报告说您的蓝牙至少已启用。
有一些iwlwifi驱动程序参数可以用来使两者更好地一起工作，如果你真的需要蓝牙的话，你可以探索一下。我没有用，所以我把它关掉了，一切都很好。
我猜发生在我身上的事情:就在我安装了14.10之后，我删除了一堆我不需要的软件包。可能其中之一是蓝牙。因此，这个问题从未出现过。然后，当我升级时，某种元数据包依赖于蓝牙，所以蓝牙被重新安装，造成了问题。这似乎也可能是发生在你身上的事。

使用"Intel Wireless 3160 AP芯片组“，我无法与任何AP(接入点)相关联。
首先，我尝试了上面的补丁(禁用11n) -但我不喜欢这个解决方案，因为我被迫使用更低的比特率。
经过一些额外的研究，我发现了这个问题--蓝牙。由于WiFi/BT共存问题，iwlwifi驱动程序正在解决这一问题。
