英特尔无线控制器 8260 在 Ubuntu 15.10 上无人认领

在新的 Thinkpad carbon 上安装 Ubuntu 15.10 后，我必须添加两个内核参数i915.preliminary_hw_support=1才能nolapic使 Ubuntu 正常运行。安装似乎没问题，但 wifi 控制器不起作用。

以下是和的输出lshw -C network：lspci -nnk | grep 0280 -A2dmesg | grep iwl

sudo modprobe iwlwifi没有返回任何内容，以太网连接正常。所以看起来我的 wifi 控制器固件有问题。我已经做了一些更新，并尝试了其他帖子中的建议，但都没有成功。

那么有人能解决我的问题吗？提前谢谢！

无线控制器不再无人认领，但它仍然无法工作。dmesg | grep iwl现在的输出是

有趣的是，当我跑步时，sudo modprobe -r iwlwifi我sudo modprobe iwlwifi的笔记本会冻结，我必须按下电源按钮才能关闭。重新启动后，就可以sudo modprobe iwlwifi正常工作了。

答案1

您缺少最新固件。您可以打开终端并执行以下操作来安装它：

sudo apt-get update
sudo apt-get install git
git clone https://github.com/OpenELEC/iwlwifi-firmware.git
cd iwlwifi-firmware/firmware
sudo cp iwlwifi-8000*  /lib/firmware
sudo modprobe -r iwlwifi
sudo modprobe iwlwifi

你的无线网络应该可以正常工作。不过可能需要重新启动。

如果此固件无效，请尝试：

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.157_all.deb
sudo dpkg -i linux-firmware*.deb

重启。

我建议我们暂时尝试使用较新版本的驱动程序。请将此文件下载到您的桌面：https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v4.4.2/backports-4.4.2-1.tar.gz右键单击它并选择“在此处提取”。现在返回终端：

cd ~/Desktop/backports-4.4.2-1
make defconfig-iwlwifi
make
sudo make install

重启。如果这个和固件都有效，我建议我们安装整个 4.4.6 内核。

注意：假设您的安装是英文的；如果不是英文，并且桌面名称不同，请用上面的内容替换。例如：

cd ~/Escritorio/backports-4.4.2-1

让我们尝试更新的固件文件：

cd /lib/firmware
sudo wget https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/linux-firmware.git/plain/iwlwifi-8000C-19.ucode
sudo wget https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/linux-firmware.git/plain/iwlwifi-8000C-21.ucode

重启。然后再次粘贴：

dmesg | grep iwl

回顾你上次的贴子，我非常关心这一点：

[2.678204]iwlwifi 0000：04：00.0：pci_enable_msi 失败（0Xffffffda）

我认为这个错误报告与以下相关：https://bugzilla.kernel.org/show_bug.cgi?id=114101建议添加启动选项中断轮询。

请执行以下操作：

gksudo gedit /etc/default/grub

如果您没有文本编辑器 gedit，请使用 nano 或 kate 或 leafpad。找到以 GRUB_CMDLINE_LINUX_DEFAULT 开头的行，并将 irqpoll 添加到末尾。结果应类似于：

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash irqpoll"

仔细校对，保存并关闭文本编辑器。现在执行以下操作：

sudo update-grub

重新启动并再次显示：

dmesg | grep iwl
