I did try that before - didn't help.
try to disable the Wi-Fi Direct
Suddenly my Phaser 3052 dissappear from my local network and I can't get it back there. USB connection works fine but when try Easy Wireless Setup it can't connect. It says that security settings doesn't match but they do. Look at the screenshots:
Of course I tried different settings on both router and printer without any success. I've also tried to connect with WiFi Direct from Android phone - it found printer but couldn't connect.
Any suggestion how can I debug this issue? Maybe there are some detailed logs that are generated during setup?
