为什么我无法连接无线网络?

为什么我无法连接无线网络?

似乎是一个重复的问题,但我无法在问题数据库中找到答案,所以我将从我拥有的适配器开始:

lspci | grep Network

06:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

iwconfig eth1

eth1      IEEE 802.11abg  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

lsb_release -a

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 12.04.2 LTS
Release:    12.04
Codename:   precise

编辑 3:检测到无线网络,但无法连接任何网络。

编辑4:我有 Windows 7/XP 和 Ubuntu 双启动,两个 Windows 都可以正常连接到任何无线。

配置共享 WEP 密钥后连接到多个 WEP 连接 / 更新后似乎破坏了身份验证,并且它总是不断询问密钥,即使它是正确的。我可以使用“安装时更新”功能完美地使用基本 12.04 安装连接到无线。

我已经激活了 jockey Broadcom STA 驱动程序。

怎么了?

编辑4:第一次编辑的来源:如何安装 Broadcom / STA 无线网卡(BCM43XX)

编辑:bcmwl 内核源已经是最新版本;linux-libc-dev、libc6-dev、linux-headers-generic、linux-headers 也是如此;使用 ndiswrapper 进行黑名单也无济于事;使用 modprobe 删除也不起作用

编辑 2:重新安装 bcmwl-kernel-source,如如何让我的 BCM43228 卡在主线内核 3.4 或更高版本中工作?输出:

sudo apt-get install --reinstall bcmwl-kernel-source
