更新到内核 4.10 / 4.11 后没有 wifi - Ubuntu 14.04

  • 772

我的 wifi 不再在内核 4.10 / 4.11 下工作。dmesg | grep iwl这是内核 4.11 下的输出

[    2.307045] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-7260-17.ucode failed with error -2
[    2.307049] iwlwifi 0000:02:00.0: no suitable firmware found!

这是内核 4.4 的输出 - wifi 功能正常

    您可以安装缺少的固件 

    cd /lib/firmware
    sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwlwifi-7260-17.ucode

    然后重启进入内核 4.10

    iwlwifi-7260-17.ucode 文件不在 14.04 的 linux-firmware 包中
