[语境]
我正在我的新电脑上安装 Debian：uname -a是Linux myname 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3+deb7u1 x86_64 GNU/Linux。
我正在尝试使用我的 wifi，lspci结果显示02:00.0 Network controller: Intel Corporation Centrino Wireless-N 135 (rev c4)。非免费软件包iwlwifi已安装并iwlwifi-135-6.ucode位于/lib/firmware。我的版本是 18.168.6.1，因为http://wireless.kernel.org/en/users/Drivers/iwlwifi
网络管理器设法查看网络几秒钟，尝试连接，然后断开连接，然后尝试再次连接......以下是摘要dmesg：

如果我输入sudo modprobe -r iwlwifi ;sudo modprobe -a iwlwifi
，我会得到（在 dmesg 中）：

由于问题似乎来自 rfkill，我尝试了类似 的方法sudo rfkill unblock all
。但是，每当我输入 时sudo rfkill list all，我都会得到：
1: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
3: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
看来硬件交换机没有问题...我还监控了 rfkill() 事件sudo rfkill event，得到了以下结果：
1400772407.995946: idx 3 type 1 op 2 soft 0 hard 0
1400772410.003509: idx 3 type 1 op 2 soft 0 hard 1
1400772410.004361: idx 3 type 1 op 2 soft 0 hard 0
1400772412.012073: idx 3 type 1 op 2 soft 0 hard 1
1400772412.013314: idx 3 type 1 op 2 soft 0 hard 0
仅当尝试连接时才会切换 rfkill。
这可能是与飞行模式有关的问题，但我电脑上的灯不亮。我试图按 fn+f11 来打开它，但灯一直没有亮...我看不到任何与电脑上的 wifi 相关的机械开关或 fn+...。遇到与飞行模式相关的问题的人似乎通过启动 ubuntu 10.10 来解决这个问题...安装 debian squeeze 或 Ubuntu 能解决这个问题吗？
[问题]
以下是我的问题：
这看起来像是硬件问题吗？火焰喷射器是解决这个问题的正确工具吗？
我如何找到不时阻止 rfkill 的原因？固件可能是导致此问题的根源吗？
你会尝试什么？我可以尝试什么？
任何意见将是有益的 ！
答案1
我正在回答我自己的问题，因为其他人可能有同样的麻烦，并且我有一个解决方案可以建议...它对我有用，所以......
我没有完全理解我的问题，但最后，我下载了 ubuntu 14.04 LTS，http://www.ubuntu.com/download/desktop我将图像复制到了 USB 棒上。
我在 USB 上启动。系统提示我选择试用版还是安装版。我选择了试用版。在试用版中，我设法在不到 3 分钟的时间内连接了我的 wifi...我关闭了 ubuntu 并重新启动了 debian。问题解决了！
我正在通过无线连接写这篇文章。我想我会在身边放两个 USB 插槽：一个用于强大的 Debian，另一个用于出色的 ubuntu！
