我的笔记本电脑上的 wifi 适配器有两个问题。
- Ubuntu 20.4.3
- 网络控制器：Intel Corporation Wireless 3165（rev 81）
当我关闭 wifi 或打开飞行模式时，我无法重新打开 wifi。它无法识别适配器。当我关闭并再次打开时，它就可以正常工作。
有时 wifi 连接会突然断开。我旁边的调制解调器信号功率很好。它不会连接另一个网络，日志记录如下所示：（当我关闭并再次打开时，它就可以正常工作。）

我不确定，但当我使用浏览器 vpn 扩展（firefox 和 opera 上的 cyberghost）时，我似乎遇到了“问题 2”。也许这可以给你一些线索。我不知道。

答案1
您的数据表明您需要安装另一个驱动程序才能使 WiFi 正常工作。
如果你有这些文件：
iwlwifi-7265D-13.ucode and iwlwifi-7265-13.ucode
将其重命名为：
iwlwifi-3165-9.ucode and iwlwifi-3165-13.ucode
之后重启
