安装 backport-iwlwifi-dkms 后网络密码被拒绝

  • 772

在新的联想 P53 上全新安装 Kubuntu 19.10。

起初 Wifi 网络正常工作，我可以使用常用密码连接到我家的 Wifi。

驱动程序管理器建议安装backport-iwlwifi-dkms，我这样做了，但现在密码被拒绝了。我也试过我的手机热点（有一个相当简单的密码），它也被拒绝了。如果我将其重新配置为无密码，我可以连接到手机热点。

可以显示密码并且没问题，我什至复制/粘贴了它。

来自 /var/log/syslog 的连接序列日志（似乎它首先尝试使用存储的密码进行连接，这很可能也是正确的密码）：

    无线网络工作。您安装了新的驱动程序。无线网络坏了。

    如何重新安装前一个（驱动程序）？

    dkms status
backport-iwlwifi, 7906, 5.3.0-26-generic, x86_64: installed

    要删除backport-iwlwifi-dkms驱动程序，并恢复为原始iwlwifi驱动程序...

    sudo dkms remove backport-iwlwifi/7906 -k 5.3.0-26-generic

    reboot

    注意：根据这篇文章，backport-iwlwifi-dkms 不能与内核 5.0.0+ 一起使用
