我在这周安装了Ubuntu 18.04 LTS,现在我的wifi连接有问题。WiFi连接每5-10分钟自动断开连接,但wifi信号仍然良好。
我进行了搜索,找到了旧版Ubuntu的一些答案,并尝试了一下,但问题仍未解决。
这是我的无线适配器信息:

man journalctl
。该--follow

resolvconf
软件包,添加nameserver 8.8.8.8
到/etc/resolvconf/resolv.conf.d/tail
文件并/etc/resolv.conf
使用sudo resolvconf -u
命令重新生成文件。第二个是编辑/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
文件并更改wifi.powersave = 3
为wifi.powersave = 0
。
journalctl --follow
在终端窗口中运行来获取更多信息。然后,当您的WiFi掉线时,查看消息。
