bcmwl-kernel-source 在内核上损坏：5.8.0-7630-generic

我的无线网卡出现了几个问题。

重新启动后（我认为是在内核更新后）我在网络设置中看不到网卡，但可以使用来看到它lspci。

遵循本指南安装 Broadcom 无线驱动程序

这对我的 PCI.ID - 14e4:4331 (rev 02) 建议：

sudo apt install firmware-b43-installer

sudo apt install linux-firmware

似乎部分起作用了。Wifi 可用，但仅限 2.4GHz 信道。

所以我也尝试了 bcmwl-kernel-source。

问题似乎在于 bcmwl-kernel-source 无法在最新内核 5.8.0-7630-generic 上正确编译。（尝试从“附加驱动程序”安装时会获得类似结果）：

有没有什么办法可以在这个内核上修复这个问题？

lshw -class network以下是有帮助的结果：

答案1

作为临时修复，我启动了 5.4.0-59-generic 内核。

  1. 在启动期间，在 Grub 屏幕上，选择选项＃2（ubuntu 的高级选项）。
  2. 然后选择第三个选项（“Ubuntu，带有 Linux 5.8.0-34-generic”）

重新启动后，您的系统应该可以接收 wifi 适配器。

要使启动进入 5.4.0-39-generic 成为默认选项：

  1. sudo emacs /etc/default/grub # 或者使用您喜欢的编辑器
  2. 编辑 GRUB_DEFAULT 行以读取GRUB_DEFAULT="1>2"
  3. 保存并退出编辑器
  4. sudo update-grub

这GRUB_DEFAULT="1>2"告诉 Grub 菜单在第一个屏幕上选择第二个选项（从 0 开始计数）（即“Ubuntu 的高级选项”），然后在第二个屏幕上选择第三个选项（也从 0 开始计数）。您可以让 Grub 屏幕超时或按两次回车键，这样就可以将您引导到内核版本 5.4.0-39-generic。

正如我所说，这是我的临时解决方案。我认为永久解决方案可能需要供应商提供驱动程序更新。

答案2

为 5.8.0-7630-generic 构建初始模块

Ubuntu 存储库中包含的默认驱动程序包显然无法编写为支持每个内核版本（例如 5.8.0-7630）。但是，它确实支持默认的 Ubuntu 内核版本。例如，从我的机器上：

$ uname -r
5.8.0-34-generic

和：

$ sudo dpkg -s bcmwl-kernel-source
Package: bcmwl-kernel-source
Status: install ok installed

我建议您恢复到标准的 Ubuntu 内核和头文件版本。然后软件包应该可以干净地安装。

然而，如果它支持 5 gHz 通道，我会感到非常惊讶。

答案3

我所做的只是删除 5.8.0-34-generic 内核，现在它运行完全正常。

我没有寻找任何其他解决方案，因为我有一个计算机科学项目需要在两天内完成。
