我在 Ubuntu (16.04) 中定义了一个连接，使用配置为热点的 WiFi 将我的以太网连接共享给其他设备。直到今天，它都运行良好。每次我尝试连接到我的电脑时，WiFi 都会中断，并出现一条消息，提示“已断开连接”并消失，单击网络图标会告诉我 WiFi 网络尚未准备好。谷歌搜索后，我发现我可以使用以下方法重置它：sudo service network-manager restart。重置（或重新启动）后，WiFi 似乎可以正常工作，但如果我尝试共享我的以太网连接，它又会中断。
可能是周末的更新破坏了该功能。
我该怎么办？我应该运行哪个命令来为您提供更多信息？
执行dmesg这是我所知道的唯一检查 Linux 问题的命令，它告诉我一个分段错误：

您可以看到，我断开了之前的 WiFi 连接，并且当我尝试从设备连接时，连接就中断了。
谢谢。
