断电重启下试下，

还是不行，试了好多遍了。应该怎么排查？

现在是显示出来的，但是根本扫描不到任何wifi，这也太奇怪了吧

ifconfig -a
wlan0     Link encap:Ethernet  HWaddr 00:E0:4C:6D:E8:1B
          BROADCAST MULTICAST  MTU:1500  Metric:1

wpa_cli -i wlan0 scan
OK
wpa_cli -i wlan0 scan_result

只支持2.4G wifi，不支持5G

我也是遇到这样的问题，使用micropython时能连上，断电重启，重刷系统都不行：

[root@canaan ~ ]#sta.sh wlan0 T 00001111

+ ssid=T

+ grep wpa_supplicant
+ grep -v grep
+
+ killall wpa_supplicant
+
+ sleep 10
+ wpa_supplicant -D nl80211 -i wlan0 -c /etc/wpa_supplicant.conf -B
