从昨天开始,我就遇到了无法在笔记本电脑上使用 W-LAN 或蓝牙的问题。我从其他线程运行了几个命令(见下文),但都无济于事。最后,我用安装的另一个内核启动了系统,最后 W-LAN 又恢复了工作。

今天,昨天的问题又出现了,但这次我不知道该怎么解决。任何帮助都非常感谢。

这里,错误输出看起来与我得到的类似,但执行命令rmmodmodprobe没有帮助。 也没什么帮助。

系统操作系统:Ubuntu 20.04.3 LTS使用内核5.4.0-89-通用 x86_64

按照@unbi-rabka 的回答并没有解决问题。我仍然没有无线连接

我还尝试在当前安装的同时安装全新的 Ubuntu-18.04。但这也无济于事。

答案1

我最近(2022 年 8 月)才遇到这个问题,之前使用英特尔 3160 wlp2s0 多年都没有问题。我怀疑这是 20.04 的增量升级之一。我通过升级到 22.04 解决了这个问题

答案2

我使用 kubuntu 20.04 和 Wifi 6E AX210

更新操作系统后我遇到了同样的问题,所以我在我的电脑上尝试了这个,并且成功了

mv /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm.bak

重命名后,你必须重新启动电脑

答案3

对于来这里寻找解决方案的其他人,我也遇到过类似的问题,我的笔记本电脑20.04, 与英特尔 9461适配器。

在我看来,这是内核/驱动程序/固件不匹配。我可以通过升级linux-firmware软件包来解决这个问题。为此,我查看了这一页查看此包的可用版本20.04更新发布。

我下载了最新版本,但问题依然没有解决,因此我尝试了比现有版本更新的版本。20.04,来自21.04(希尔套房)并且是版本1.197。 这充分解决了问题,并且不应该被更新破坏,假设任何linux-firmware更新20.04维护其版本方案。任何对此软件包的更新焦点存储库将被版本化1.187.x > 1.187.29,其版本将高于当前版本,但总是低于1.197...

以下是链接到镜像页面直接下载1.197该版本的linux-firmware软件包。

编辑:划掉!看起来wpa-supplicant.service已经重启了期间的 apt 安装1.197,并且恰好在 中存在唯一可用的固件文件时发生这种情况/lib/firmware/。随后,降级版本1.187正在提供一个有效的组合。

我已将该包固定到该1.187版本,现在它实际上可以运行,即使在重新启动后也是如此。

这是我所做的20.04
