我有一台运行 Ubuntu 19.10 的联想 X1 Carbon
大约一个月前，我的 wifi 开始随机断线。断线时，Wifi 仍显示已连接状态。
当这种情况发生时，为了修复它我需要sudo service network-manager restart每 5 分钟左右执行一次。
我尝试过的事情：
- 禁用 ipv6
- 禁用 wifi 电源管理（https://askubuntu.com/a/1077559/1072078）
sudo apt install backport-iwlwifi-dkms- 还有一些我记不清的事情
sudo lshw -C network输出结果如下：
*-network

有什么想法可以解决这个问题吗？这让我有点抓狂。
