Ubuntu Intel无线3160 AC不工作/慢/断开/不稳定
我刚买了一台带有intel无线3160AC模块的东芝l50-b-1q0。
我已经安装了ubuntu 12.04（我听说14 natty更糟）并尝试了不同的内核：3.12rc4,3.11,3.13.2,3.17。 但我总是遇到同样的问题。 无线连接要么很慢要么连接断开，但结果是它无法使用。 我也尝试使用后端版本3.16.1和3.13.2-1中的iwlwifi。 总是同样的问题。 此外，我已经尝试使用固件iwlwifi-3160-ucode-9，iwlwifi-3160-ucode-8，iwlwifi-3160-ucode-7作为内核3.11,3.13.2,3.12rc4。 没运气。 我也尝试过切换到wicd而不是网络管理器，但问题仍然是一样的。
目前我不知道该怎么办，这非常令人沮丧。 我不得不说我有一个全新的hp 15-n234sl与Realtek 8188ee无线模块有类似的问题。 我认为问题是Realtek芯片，我把它更改为东芝，因为它有英特尔无线模块应该更好。 我开始认为Ubuntu中存在新的无线模块问题，但没有人知道或理解它。
如果您有任何建议，请帮助我。

只是每个人使用英特尔无线3160ac的更新（我猜也是7260）。 阅读错误报告： https ： //bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1354975
我打开了Ubuntu 14.04并安装了内核3.13.0-37_3.13.0-37.64 + iwlltr0001来自： http ：//people.canonical.com/~sforshee/iwl-ltr/trusty/
然后我从backports3.16-1和intel固件iwlwifi-3160-9-ucode安装了最后一个iwlwifi。
之后，我输入了一个终端：
$echo "options iwlmvm power_scheme=1" | sudo tee /etc/modprobe.d/iwlmvm.conf
$echo "options iwlwifi bt_coex_active=Y swcrypto=1 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
$sudo reboot
目前，经过3个多小时的测试（连续导航），wifi连接稳定（没有断开连接），没有应有的速度，但似乎可以使用。 如果您对如何改善连接有任何想法，请告诉我。
我希望有人会发现这篇文章很有用。
我遇到了类似的问题。 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 / firmware中。 重启后一切正常。 我安装了linux-firmware和linux-firmaware-nonfree软件包，但我认为这些软件可能有旧版本的固件。
无论如何，我希望这可以帮助有类似问题的人。
使用“Intel Wireless 3160ac芯片组”，我无法与任何AP（接入点）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，因为我强迫使用较低的比特率。
经过一些额外的研究，我发现了问题 – 蓝牙。 它正在iwlwifi驱动程序中解决，因为WiFi / BT共存问题。
==== FIX ====
[超级简单] – 禁用bt_coex_active标志：
echo options iwlwifi bt_coex_active=0 | sudo tee /etc/modprobe.d/iwlwifi.conf
尝试关闭蓝牙（例如使用rfkill）。
从14.10升级到15.04后，我遇到了类似的问题。 我有一个碳X1，但它也使用iwlwifi。 我通过使用rfkill关闭蓝牙来解决问题。 iwlwifi驱动程序的页面表明同时运行wifi和蓝牙很困难。 我注意到该脚本报告您的蓝牙至少已启用。
有一些iwlwifi驱动程序参数可用于尝试使两者更好地协同工作，如果你真的需要蓝牙，你可以探索。 我没用它，所以我把它关掉了，一切都很好。
我对发生在我身上的事情的猜测：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，其中一个是蓝牙。 因此问题从未出现过。 然后当我升级时，某些ubuntu-basic-packages-we-figure-everyone-will-want元数据依赖于蓝牙，因此蓝牙被重新安装，从而产生了问题。 这似乎也可能发生在你身上。
