ubuntu 22.04 找不到 wifi 适配器

Question

按照这个解决方案 uname -f回来5.19.0-43-generic 后，我拔掉充电器，关闭机器，按下电源按钮，等了 5 分钟，打开它，然后就出现了 wifi。

现在，当我这样做时，sudo lshw -C network第二个条目已更改为

*-network

现在lspci输出

这在很大程度上是相似的，但是类似的事情 Network controller [0280]: MEDIATEK Corp. Device [14c3:7922] 已经改变了 Network controller [0280]: MEDIATEK Corp. Device 7922

如果有人知道为什么，请发表评论？
