我无法在我的 Toshiba Satellite U200 上连接 Wi-Fi，尽管无线网卡似乎没有被阻止：
$ rfkill list
0: Toshiba Bluetooth: Bluetooth
Soft blocked: no
Hard blocked: yes
6: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
注意：当我启动它时是被阻止，但正在执行：
modprobe -rfv iwl3945
rfkill unblock all
modprobe -v iwl3945
解除阻塞。LED 不会亮起。使用硬件按键不会改变任何内容。
的输出lshw为：
$ sudo lshw -C network

[ 1336.470773] iwl3945 0000:02:00.0: Radio disabled by HW RF Kill switch
有人知道这是什么问题以及如何解决吗？
答案1
好的，我明白了。侧面有一个小的硬件开关，可以关闭。这通过以下方式指示dmesg：
[ 1336.469707] iwl3945 0000:02:00.0: Radio disabled by HW RF Kill switch
但是我不知道为什么rfkill list这么说hard blocked: no......
