Ubuntu wifi 问题

您好，我在电脑实机上装了Ubuntu 24.04。

问题：电脑开机后使用一段时间，会出现提醒 “Activation of network connection failed“。然后，右上角的wifi标志会消失，在设置中搜索不到任何一个wifi。

尝试解决：我试了重启NetworkManager (sudo service NetworkManager restart)，没有效果。只有重启电脑才可以解决这个问题。

日志：我用journalctl抓取了问题发生时的日志，大概是jun 30 16:45 ~ 16:55。我看了这个日志，虽然我看不太懂，但是问题大概发生在16:49:22左右。这是日志的链接：[](【腾讯文档】journalctl_log

请根据日志帮我找到问题的原因，并推荐给我解决的方案，非常感谢！

    从您提供的日志来看，问题可能出在您的网络连接配置文件中。这可能是由于系统启动时没有正确地加载这些配置而导致的问题。为了更好地诊断问题，您可以尝试以下步骤：

    1. 检查网络服务状态：

      • 首先，确认network.service是否正在运行。 
        systemctl status network.service

      如果它不在运行状态，可以尝试重启网络服务。

      systemctl restart network.service

    2. 检查DNS服务器配置：

      • 检查 /etc/resolv.conf 文件中的DNS记录是否有错误。
      • 使用 dig 命令查看DNS解析情况： 
        dig www.google.com @8.8.8.8

      如果出现解析失败的情况，可能是因为DNS服务器配置有误。

    3. 检查防火墙设置：

      • 确认防火墙规则没有阻止您的网络连接。 
        firewall-cmd --state

      可能需要关闭不必要的防火墙规则。

    4. 重新安装或更新软件包：

      • 清除所有已安装的网络相关的软件包。 
        apt-get autoremove network-manager*
apt-get clean

      然后尝试安装最新的版本。

    5. 手动添加网络设备：

      • 如果上述方法都不能解决问题，考虑手动添加网络设备。
