联想 Wifi RTL8822BE 无法在 Ubuntu 18.04 上运行

我是 Linux 新手，我在笔记本电脑上使用 Linux，但唯一的问题是，在笔记本电脑安装 Windows 之前，WiFi 无法使用，而现在 WiFi 可以工作

我认为这些信息可以帮助找到解决方案

如果我sudo modprobe rtwpci什么也没返回。

如果我做 lsmod | grep rtw

返回

rtwpci                 24576  0
rtw88                 610304  1 rtwpci
mac80211              851968  2 rtwpci,rtw88 
cfg80211              712704  2 mac80211,rtw8

如果我这么做 lspci -nnk | grep 0280 -A3

我明白了
