I was shocked to find out that my children were just typing in telstra gateway and they had complete access to the home gateway no siging in at all required. I to tried and there it was password, all devices on my wifi. How do i stop this, has it been set up wrong please help. Partenal Control is useless when they have control of the gateway so easy.
Smart kids. I am assuming that they were at home when they did this and not down at the shops.
You need to log in to the modem and change the admin password for the modem (not the wifi password).
