我有一台 System 76 serval。wifi 经常停止工作，需要重新启动网络管理器服务。它会自行死机，但可以通过切换 wifi 3 次（有时更多，有时更少）来触发！
当它工作时，我有：
% usr/bin/sudo nmcli device
DEVICE TYPE STATE CONNECTION
wlp62s0 wifi connected ATT964
p2p-dev-wlp62s0 wifi-p2p disconnected --
enp59s0 ethernet unavailable --

如果我使用任务栏上的选择网络命令在两个 wifi 路由器之间切换三次（有时更多次），wifi 就会停止工作。
发出上述命令会产生以下差异：
% /usr/bin/sudo nmcli device

enp59s0 ethernet unavailable --
wlp62s0 wifi unavailable --
