我的 wifi 在内核 4.10 / 4.11 下无法正常工作。以下是内核 4.11 下的输出

以下是内核 4.4 的输出 - wifi 功能正常

有什么建议可以解决这个问题吗?
答案1
您可以使用以下方式安装缺失的固件
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
