下载此到桌面https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.18.1/backports-3.18.1-1.tar.xz 右键单击并选择在此处提取然后

sudo apt-get update
sudo apt-get install linux-headers-generic build-essential

cd ~/Desktop/backports-3.18-1
make defconfig-iwlwifi
make
sudo make install

重启后,如果你有固件,它应该可以工作,你可以这样做来检查ls /lib/firmware/ | grep iwlwifi-7260

我希望下一次内核更新能够在 14.10 中修复此问题,因为最近已对 14.04 内核进行了修补,以修复 (rev cb) 卡的问题
