ESP32 Forum

版本: esp32 idf v4.4
ssid和密码都是正确的，大部分情况下能够连接上wifi，但有时连接不上，失败reason,有时是 14,有时是 25,
有人遇到过没有？

把所有日志全打开后的打印如下：

WiFi 是 2.4G/5G 双频的 WiFi 吗，如果是的话，是否两个频段的 SSID 和密码是相同的？

你好，请问这个问题你这边解决了吗？怎么解决的呢？

请检查路由器是否启用了 2.4G 和 5G，并检查是否使用了相同的 SSID，如果还是遇到改问题，请提供复现的示例或链接。

是路由器的问题，不是esp32的问题，已经解决。

楼主的路由器是什么问题
