我有一台戴尔 XPS 15 9570 笔记本电脑。过去两年我一直在使用 Ubuntu（18、19 和 20）。除了 wifi 会随机停止工作外，其他一切都运行良好。有时我只需关闭并打开 wifi，它就会继续工作，直到下一次随机崩溃。但是，其他时候，当这种情况发生时，我无法关闭 wifi，好像系统崩溃了，我必须硬关机笔记本电脑，然后启动后它才能再次工作。
当前 ubuntu 版本：
20.04 LTS
核心：
5.4.0-26-generic
BIOS 版本（sudo dmidecode -s bios-version）：
1.15.0
这是输出sudo lshw -class network
