无法连接 wpa_supplicant

我尝试使用 wpa_supplicant 连接 wifi（WPA2）

有任何想法吗？

谢谢！

答案1

您正在关联，然后在完成四次握手之前断开连接（我没有看到 802.11 身份验证步骤，但这可能是因为没有它您就无法关联）。
我大胆猜测这是由以下原因之一造成的：

1) 您的 PSK 不正确（很可能）。2
) 由于某种原因，您已被 AP 列入黑名单（尝试重新启动 AP，或等待一段时间）。3
) AP 上存在错误。目前尚不清楚 DISCONNECT 事件是否是因为 AP 正在解除您的关联/取消认证，还是请求者本身正在断开连接。如果请求者在超时内未收到握手的 M1，则可能会这样做，而这又可能是因为 AP 处于奇怪的状态。再次重置它以清除。

一次 wireshark 捕获，最好是从监控模式下的独立 wifi 卡获取的空中跟踪，或者最坏的情况下是从 bamt-miner 机器本身获取的捕获，捕获其 wifi 接口将有助于更好地了解正在发生的事情。您还可以在 dmesg 中获得一些有用的驱动程序日志。
希望对您有所帮助！
