问题描述
我有一台运行 Ubuntu 13.10 的戴尔 XPS 12，但它似乎没有发现它是无线的。我已经尝试了 here 的建议，但它们没有任何区别

我发现它似乎正在加载旧版本的固件，但我不知道如何或为什么
peter@xps:/lib/firmware$ modinfo iwlwifi | grep 7260
firmware: iwlwifi-7260-6.ucode
peter@xps:/lib/firmware$ ls *7260-6*
ls: cannot access *7260-6*: No such file or directory
任何有关如何获得此设置的建议都非常受欢迎。
最佳答案
我建议你把它下载到你的桌面： http://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.11-rc3/backports-3.11-rc3-1.tar.bz2 右键单击它并选择 ‘Extract Here.’ 现在打开一个终端并执行：
cd Desktop/backports-3.11-rc3-1/
make defconfig-iwlwifi
make
sudo make install
现在在此处下载所需的固件：https://git.kernel.org/cgit/linux/kernel/git/egrumbach/linux-firmware.git/plain/iwlwifi-7260-7.ucode 现在打开一个终端并执行以下操作：
sudo cp ~/Desktop/iwlwifi-7260-7.ucode /lib/firmware/ <--or wherever you downloaded it
sudo modprobe -r iwldvm <--If it is not loaded, OK, please proceed
sudo modprobe -r iwlwifi <--If it is not loaded, OK, please proceed
sudo modprobe iwlwifi
您的无线现在应该可以工作了。
