你能帮忙工作吗？
答案1
您将需要 12.04 版中该卡的反向移植
sudo apt-get install linux-headers-generic build-essential
wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.19-rc1/backports-3.19-rc1-1.tar.gz
tar -zxvf backports-3.19-rc1-1.tar.gz
cd backports-3.19-rc1-1
make defconfig-iwlwifi
make
sudo make install
你需要固件
wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-7260-ucode-23.15.10.0.tgz
tar zxvf iwlwifi-7260-ucode-23.15.10.0.tgz
sudo cp iwlwifi-*.ucode /lib/firmware
重启
如果你发现你的 wifi 以后无法使用，很可能是内核更新了，你需要
cd backports-3.19-rc1-1
make clean
make defconfig-iwlwifi
make
sudo make install
重启 wifi
