无无线网络，BCM4313

刚买了这台华硕 10 英寸笔记本电脑，附带 Ubuntu 12.04。我家里的一切都很好：无线识别并连接。

我一到女友家，麻烦就开始了。

我无法连接到无线（身份验证...超时并要求身份验证）

我开始在网上搜索，尝试了使用终端命令在网上发布的一些解决方案。没有解决方案。我决定升级到 12.10-13.04，这给我带来了更糟糕的问题：我再也看不到任何网络了。

无线网卡已打开，毫无疑问。有线连接正常。

我一直在摸索各种驱动程序版本，但毫无进展，也不知道我当前运行的是哪个驱动程序

我对于要运行哪些终端线路有一个模糊的想法：

我是新手，很高兴开始我的 Ubuntu 和 Linux 生活，我确信这只是我遇到的几个小问题中的第一个！:) 感谢大家

现在重启

答案1

请尝试：

sudo apt-get purge bcmwl-kernel-source
sudo modprobe -rv wl
sudo modprobe -v brcmsmac

如果有任何错误，请继续执行命令然后重新启动。如果您没有安装除 wl 驱动程序之外的任何其他驱动程序，那么您的无线应该可以正常工作。

答案2

在 Ubuntu 13.04 中，我相信默认的 bcmwl-kernel-source 将无法在您的 Broadcom 4313 上正常工作。我建议您获取临时的有线以太网连接并打开终端：

sudo apt-get remove --purge bcmwl-kernel-source
wget http://us.archive.ubuntu.com/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_5.100.82.112+bdcom-0ubuntu3_amd64.deb

或者，如果你的系统是 32 位：

wget http://us.archive.ubuntu.com/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_5.100.82.112+bdcom-0ubuntu3_i386.deb

确认 32 位或 64 位：

arch

然后做：

sudo dpkg -i bcmwl*.deb

重新启动并向我们提供您的报告。

断开以太网。wl 模块是否已加载？

lsmod | grep wl

如果没有，则明确加载：

sudo modprobe wl

现在怎么样？接口扫描了吗？

sudo iwlist eth1 scan
