I would like to raise the level of my security. Often, I use my Sony E2303 like a wifi hotspot, but I don't know how to turn off WPS pin implementation.
Android 5.0 lolipop (root) patch level secured:2015-11-01 Compilation: 26.1.A.3.111.
Ok, I solved it by turn on Invisible Mode (BSSID) after the first connection to my hotspot. (next will be automaticly if you use auto-connect Network settings in your PC, or if you know BSSID you still can connect from your terminal).This is in Tethering/Hotspot settings on your android smartfon.
