有人知道该怎么做吗？
答案1
消息“原因：15=4WAY_HANDSHAKE_TIMEOUT”表明密码有问题。我假设您已经仔细检查过在 Ubuntu 和 Windows 中输入的密码是否正确。请在路由器的管理页面中再次检查以验证。
接下来，有两种方法可以实现加密，硬件和软件。尝试禁用硬件加密，看看是否有帮助。请打开终端并执行以下操作：
sudo modprobe -r ath9k
sudo modprobe ath9k nohwcrypt=1
现在您可以连接了吗？如果可以，我们将使更改永久生效：
sudo -i
echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf
exit
如果仍然无法连接，请再次检查路由器中的加密密钥。仅使用数字和字母，不要使用符号或空格。重新启动路由器。
接下来我们看到：
ath：正在使用的国家 alpha2：AU
我建议明确设置你的监管范围。检查你的：
sudo iw reg get
如果您选择 00，则这是一个通用的设置。请在此处查找您的设置：http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2然后暂时设置一下：
sudo iw reg set IS
当然，如果不是冰岛，请替换您的国家代码。永久设置它：
gksudo gedit /etc/default/crda
如果您没有文本编辑器 gedit，请使用 nano 或 Kate 或 leafpad。
将最后一行改为：
REGDOMAIN=IS
仔细校对，保存并关闭文本编辑器。
答案2
我遇到了 4WAY_HANDSHAKE_TIMEOUT，因为站点尝试使用 WPA3，但接入点（带有 NetworkManager 的热点）仅支持 WPA2。修改站点/客户端配置以使用 WPA2 解决了该问题。
