Hi @Trixynsw
Welcome to the Community!
Using your community details, I was able to check your account and find out that you've already spoken with our Technical Team earlier. From what I gathered, they were able to get you WIFI working again by performing a modem reset.
As for setting up Parental Controls, I suggest that you visit the following community threads:

Let me know if we can be of further assistance.
