linux wlan0 网络禁用(错误 siocsifflags 操作不允许)，如何启用它？

Question

我是 Linux 新手，正在回溯，我刚刚配置了我的 USB 网络适配器 tp link 725 n 作为 wlan2。命令(lshw)显示 wlan2 的网络已禁用，我尝试了几个 rfkill 命令，但它们没有显示任何输出。

命令“ifconfig wlan2 up”给出的输出为“siocsifflags 操作不允许”。

root@bt:~# lshw -c
Hardware Lister (lshw) - B.02.14
usage: lshw [-format] [-options ...]
   lshw -version

-version        print program version (B.02.14)

format can be
-html           output hardware tree as HTML
-xml            output hardware tree as XML
-short          output hardware paths
-businfo        output bus information

options can be
-class CLASS    only show a certain class of hardware
-C CLASS        same as '-class CLASS'
-c CLASS        same as '-class CLASS'
-disable TEST   disable a test (like pci, isapnp, cpuid, etc. )
-enable TEST    enable a test (like pci, isapnp, cpuid, etc. )
-quiet          don't display status
-sanitize       sanitize output (remove sensitive information like serial          numbers, etc.)
-numeric        output numeric IDs (for PCI, USB, etc.)

执行 ifconfig 命令时您似乎不是 root...
