当我从笔记本电脑连接时，我可以成功连接，如果我不输入任何内容，连接将保持打开状态。但是，任何按键都会导致连接中断，并显示以下消息qpacket_write_wait: Connection to {ip} port 22: Broken pipe
当我搜索此错误时，所有结果都与不活动有关。在我的例子中，它不是不活动，而是发送到服务器的任何击键。
我可以连接网络上的其他计算机并发出命令。我已经通过 Ubuntu bash 终端使用 Ubuntu 16.04 Desktop 和 Win 10 进行了测试。其他机器和我的笔记本电脑之间的唯一区别是它们是有线的，而笔记本电脑是无线的。
以下是使用时连接和按键的输出ssh -vvv

我不知道为什么这种连接在其他机器上有效，但在笔记本电脑上却不行。任何帮助或指导都非常感谢。
