Wi-Fi not connecting (well, getting instantly deauthed due to
AP-STA-POSSIBLE-PSK-MISMATCH after connecting)
is apparently a relatively
common problem with IoT devices.
And most people seem to point to ESP8266-based ones.
Well, I’ve never had a problem with ESP, but today I’ve been setting up an
RTL8711AF based device (Xiaomi
qmi.powerstrip.v1) and it was failing just like that.
Turns out this device just completely fails when 802.11w Management Frame Protection is on (even optionally). Ugh. Thanks Realtek.
