我在使用 Raspberry Pi 连接特定 WiFi 时遇到问题。这是我检查时的输出/var/log/syslog：
Jun 19 09:44:52 raspberrypi wpa_supplicant[447]: wlan0: Trying to associate with 86:2a:a8:2d:35:ea (SSID='XXXX Wi-Fi' freq=2462 MHz)

但当我连接到其他wifi时，它可以成功连接：

我已经搜索了很长时间，但似乎找不到可行的解决方案。在这种情况下，可能的问题在于路由器或接入点，但在我的智能手机上，我能够连接到“XXXX Wi-Fi”。所以现在我没有主意了。任何帮助都将不胜感激。

我遇到了这个问题，这个答案帮助了。换句话说，我做到了
rmmod brcmfmac
modprobe brcmfmac roamoff=1 feature_disable=0x82000
然后wpa_supplicant像正常一样，它连接了。
