我刚安装的 Ubuntu 14.04 出现了问题。我已下载并安装了固件 (iwlwifi-2030-6.ucode)，一切似乎都正常，但我仍然无法让它工作。它说 WiFi 已通过物理开关关闭，但事实并非如此。我的朋友建议我发布这些文件的输出并在此处提问。

我检查了 BIOS 设置，它看起来是正确的。我不是 IT 专家，所以如果您需要任何进一步的信息或日志，请告诉我。在 Google 上找到的常用解决方案没有帮助，而且我经常不完全理解它们。
先感谢您！
答案1
您的无线局域网已被硬封锁。要解除封锁 -
sudo rfkill unblock all
答案2
该特定型号上没有硬件开关，只有键盘上的一个可激活无线功能的键。
按 F9 启用或禁用无线功能。
