设置 wifi 网络配置文件/etc/netctl/并运行后netctl start [my_network_profile]，我收到以下消息：
Job for netctl@wlp2s0\x2d[my_network].service failed because the control process exited with error code.
另外，我安装了 gnome 桌面环境，但 wifi 没有显示在设置或系统托盘中，就像它根本不存在一样。
输出为lspci

这是输出dmesg | grep iwl

..这是输出sudo modprobe iwlwifi

另外，当我使用时wifi-menu（在我的理解中使用 netctl），它确实运行并发现 wifi 网络，但它从未连接。
答案1
我设法通过以下方式连接它网络配置arch wiki 安装指南中的超链接（我在安装过程中跳过了），最终引导我到达此链接https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi我可以在其中下载适用于我的英特尔无线 7260 的 iwlwifi 固件，然后只需按照README 文件中的说明将iwlwifi-7260-16.ucode文件复制到目录中即可安装它。/lib/firmware/
现在它工作正常，并且在重新启动时也会自动连接。
