change AP name
use ONLY WPA2-PSK with AES
Turn off remote port admin
Turn off WIfi Admin
No that's the trick...
Save your settings in Admin menu (settings.bin) in your computer, THEN
TURN OFF ALL ADMIN login options (no login even in plugin LAN port)!!!
All is left for 'break-in' to tamper your setting is RESET BUTTON , but after reset, you can notice your wifi won't work, (wrong AP name, wrong SSID & wrong WPA2 password), the ALARM is rang
