我有一台装有 Ubuntu（已更新）的 10 年旧笔记本电脑，到目前为止一切似乎都运行正常。我的 WiFi 网络会随机断开连接并开始要求输入密码。首先，这个问题发生在我连接 5-10 分钟时。但现在它一次又一次地没有连接。以下是一些信息：

我尝试过更新到最新版本，重新安装网络管理器，无法使用 ipv6，安装 iwlwifi dkms 和很多我甚至不知道它们是干什么用的，但问题仍然存在。我甚至没有触碰我的路由器接入点的任何东西。虽然我尝试过，但步骤已发布在此链接中https://forums.linuxmint.com/viewtopic.php?t=268914

所以请帮忙！！！
答案1
一切都解决了。我不知道问题到底是什么。我收到了这条消息，“原因：15=4WAY_HANDSHAKE_TIMEOUT”，所以我尝试了以下命令：
'须藤modprobe -r ath9k须藤modprobe ath9k nohwcrypt = 1'
现在一切似乎都好了。感谢您的关注
