我的无线无法连接到 Ubuntu 12.04 LTS,新安装在我的 Dell Inspiron 1525 上

我的无线无法连接到 Ubuntu 12.04 LTS,新安装在我的 Dell Inspiron 1525 上

我是 Ubuntu 的新用户(我之前的所有经验都是在 Windows 上)。我最近为了工作开始使用双启动,所以我在 Dell Inspiron 1525 上安装了 Ubuntu 12.04。它拥有 Broadcom BCM4312 无线网卡。我可以轻松连接以太网,但我的无线网络表现得很奇怪。我可以看到所有可用的网络(显然包括我自己的网络),但每当我尝试连接它时,它都会反复要求我验证连接。我非常肯定我输入了正确的密码(WPA 安全设置),但它拒绝连接。我浏览并尝试了其他响应,但无济于事,但我对 Ubuntu 完全陌生,不知道某些终端命令实际上在做什么,所以可能是用户错误。有人愿意给我一些帮助吗?谢谢。

如果您开始遇到更多问题,您可以在终端中尝试此命令。

sudo apt-get install firmware-b43-installer

它可以在一台较旧的 HP 笔记本电脑上运行。
