只是想让大家知道,我已经解决了这个问题。不知怎么的,它在 Backtrack 5 中被关闭了,我能够使用 bt5 中的键盘命令打开无线功能。
当我跑步时
iwconfig
它说lo
没有eth0
无线扩展,但wlan0
它说
IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=off
Retry long limit:7 RTS the:off Fragment the:off
Power Management:off
我相信这就是我的问题,我只是不知道如何重新打开它
有什么帮助吗?
当我跑步的时候
lspci | grep Network
它给了我这个
02:00.0 Network controller: Intell Corporation Centrino Wireless -N +
WiMAX 6150 (rev 67)
我怎么知道我的无线被硬阻止了,因为当我运行
sudo rfkill list all
我明白了

当我跑步的时候
lshw -c network
我明白了。

我注意到的另一件事是我无法将计算机从飞行模式中移除。当我单击 Dash>Network 时,它告诉我飞行模式已打开,当我将其切换为关闭时,它说它已关闭,但我无法打开无线功能,当我关闭并重新打开网络窗口时,它又重新打开了。

进入这个

外部无线开关将其设置为

答案1
问题看起来是这样的:
ESSID:off/any
如果是这样...这将停止网络管理器:
sudo service network-manager stop
这将(手动)将 ESSID 添加到 wlan(将 $id 更改为您的无线网络名称):
sudo iwconfig wlan0 essid $id
sudo dhclient -v wlan0
这应该会让您获得一个 IP 地址。
