软件更新后 Broadcom BCM4360 无法工作

我正在运行 ubuntu 18.04，在最近的软件更新导致我的 wifi 消失之前，我的 wifi 一直没有出现任何问题。我尝试清除并重新安装 bcmwl-kernel-source 并重新启动了几次，并尝试安装该卡的特定驱动程序，但无济于事。我已验证安全启动仍处于关闭状态。

以下是

有什么想法吗？提前谢谢您！

编辑：

显然最近的内核更新破坏了 bcmwl。有一个修复程序这里，不幸的是它对我没有用，而且我仍然遇到同样的问题。

答案1

该5.3内核尚未在 Ubuntu-18.04 上得到官方支持。您手动或使用linux-generic-hwe-18.04-edge软件包安装了此内核。

这就是为什么bcmwl-kernel-sourcefrom bionicrepo 无法在您的系统上构建的原因。

bcmwl-kernel-source可以通过安装与内核版本非 LTS 版本对应的补丁来修复此问题。在这种情况下eoan。

您可以从存储库下载并安装该包eoan。 http://mirrors.kernel.org/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu5_amd64.deb
