我刚刚在同一台笔记本电脑 Dell Vostro 3560 上安装了 Ubuntu 12.04 和 Windows 7。现在,在 Windows 7 上我可以访问不同的 Wi-Fi 网络。但是,当我登录 Ubuntu 部分时(重新启动笔记本电脑后),出现了一条错误消息:
已断开连接-您现在处于离线状态
当我查看我的网络菜单(在屏幕上方栏中)时,我发现没有找到网络(并且我在该区域有几个网络)。
我尝试四处寻找,但确实找不到针对此特定问题的具体实用解决方案,如果任何人遇到并解决此问题,我将不胜感激。

- web-e 的建议搜索其他驱动程序没有显示任何内容
@WEB-E,您建议我执行以下操作:
1.检查其他驱动程序 - 没有显示任何相关结果
2.在终端中运行lspci -vvv命令。相关结果(通信 - 以太网等:

感谢 WEB-E 的持续评论,我将非常感激您的进一步回复 :-)
答案1
我无法从互联网上获取该型号的确切硬件详细信息。但是您应该检查以additional drivers
获取专有驱动程序。请按照以下步骤操作,
通过其他方法连接到互联网。
按Alt+ F2,输入
gksu jockey-gtk
按Enter
这将搜索需要安装的其他驱动程序。如果您在列表中看到 Wi-Fi 驱动程序,请安装它。
如果上述步骤不起作用。按Alt+ Ctrl+ 打开终端T,运行命令lspci -vvv
并发布结果。
您可以编辑您的问题以发布该结果。
答案2
可能是 wifi 驱动程序问题。
尝试这样
首先我们必须删除 bcmwl 内核源:sudo apt-get remove bcmwl-kernel-source
然后再次安装:sudo apt-get install bcmwl-kernel-source
答案3
试试这个。看看是否有帮助。只是一个建议。
打开终端窗口。输入以下内容:
sudo ubuntu 驱动程序
自动安装
sudo 重启
