即使外部开关已打开,联想 v570 ubuntu 12.04 无线仍被硬阻止

即使外部开关已打开,联想 v570 ubuntu 12.04 无线仍被硬阻止

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

0: Ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

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。


@belacqua

是的,当我这样做的时候,它变成了这样

0: Ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

进入这个

0: Ideapad_wlan: Wireless LAN
Soft blocked: yes
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: yes

外部无线开关将其设置为

0: Ideapad_wlan: Wireless LAN
Soft blocked: yes
Hard blocked: yes
1: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: yes

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。
