我无法让英特尔 7260 cb (IWLWIFI) 工作，Kubuntu 14.04

我购买了一款配备英特尔 7260 无线网卡的新型华硕 Q302，因为“嘿，它应该开箱即可使用”，但事实并非如此。

这台电脑只有 wifi，没有以太网插孔。因此，无法使用 wifi。目前，我通过其中一个 USB 转以太网适配器将其连接到互联网。

过去三天我一直在网上搜索，并遵循了几乎所有我找到的建议。我已经重新安装了 Kubuntu 14.04（使用 3.13 内核）三次，从英特尔网站下载了最新的 .ucode（适用于 3.13 以上内核）并将其安装在 /lib/firmware 中，我也尝试从内核 3.11 构建固件（如本文所示）关于 Intel N 7260 无线网卡的论坛帖子) 但奇怪的是，蓝牙开箱后就能正常工作。

我的机器已经是最新的，我运行了 apt-get-update 多次。

lo        no wireless extensions.

我已经与此斗争了三天，但就是搞不清到底是怎么回事。多年来，我一直在笔记本电脑上使用 Wi-Fi，但我终于遇到了对手。

如果您有任何想法/主意/任何建议。如果我不能在接下来的一两天内让它工作，我将不得不退回机器......这很糟糕，因为我真的很喜欢它（除了 wifi）。

答案1

好吧，这样过了好几天，重新安装了几次 Kubuntu 14.04，安装了 Kubuntu 13.10，安装了 Linux Mint 17，安装了 Debian，升级到内核 3.14 和 3.15 以及从内核 3.16 安装 iwlwifi 固件，但都没有解决任何问题：仍然没有 WiFi。

因此，我放弃了，把笔记本电脑退回去。我会买一台没有 7260 卡的电脑。

个人感谢 User310767。我很感激你的帮助。

希望下一代笔记本电脑能够更加成功。

如果我是你，我无论如何都会买一台不同的笔记本电脑。我不知道你是否听说过，但 7260 在几乎所有操作系统上都存在大量问题。Windows 7、8、8.1、BSD、Arch、Gentoo、Ubuntu 等。前几天，我的装有 7260 的 XPS 13 不断断开连接，我打电话给英特尔进行更深入的调查。英特尔代表的回复听起来有点低调，表示他们正在努力修复以提供更稳定的连接，但没有预计到达时间。这张卡已经推出一年了。英特尔（根据我的经验）不会不及时修复这个问题，这让我怀疑这个问题深入到了硬件层面。

就我的问题而言，我的 7260 是 M.2 规格，我很难找到替代品。戴尔一直很棒，并向我提供了一台替换笔记本电脑，以替换没有 7260 的系统，因为根据戴尔的保修规定，除了 M.2 的 7260 之外，他们没有其他产品。7260 还提供半尺寸迷你 PCIE 规格，它有各种各样的替换选项（除非你不幸拥有一个可笑的联想或惠普系统，它们将他们的卡列入白名单，因此你无法更换它们。当我担任总统时，议程上的第一项就是将这种做法 100% 定为非法）

最让我担心的是这款卡在戴尔、联想甚至 System 76 上广泛销售。这究竟是怎么回事，我完全不明白，因为有些日子我每半小时就会断线十几次。有时我会连续 3 天不断线，但它出现故障的次数绝对会让它成为交易的障碍。

无论如何，如果您想了解更多信息，请在 Google 上搜索“7260 断开连接”之类的内容。那里有很多恼火的用户......对不起，我对此事持消极态度，但我宁愿用户意识到这一点，而不是像我一样头疼。

看看这个错误报告： https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1354975

本质上安装内核 3.13.0-37_3.13.0-37.64+iwlltr0001：http://people.canonical.com/~sforshee/iwl-ltr/trusty/

并安装linux-firmware 1.127.7。

如果不起作用，您可以尝试输入：

$echo "options iwlmvm power_scheme=1" | sudo tee /etc/modprobe.d/iwlmvm.conf
$echo "options iwlwifi bt_coex_active=N swcrypto=1 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
$sudo reboot

下载 7260，解压并移至固件文件夹。
