Advice 2 : How to temporarily block Internet
The natural desire of parents is to ensure the information security of the child, limit the websites he can visit. The simplest solution is to lock the Internet at the time of the absence of parents at home.
First, create a separate account for your children with the minimum number of rights. In the "children's" accounts limit the ability to delete and install programs and create additional Internet connections and change the settings that I have at the moment. Remove the connection if it is. If you connect to the network using dsl connection, set connection to the computer only for the main account. If you are using a wi-fi router, set a password and disable its preservation in computer memory, and automatic connection. Don't forget to turn off the computer when you leave home.
You can also limit the access time to the Internet using special programs, for example, Kaspersky CRYSTAL. A feature of this, is that you can set the exact time at which Internet access is prohibited, and users, to be subject to this limitation. The easy option is also the setting of the password is guaranteed to protect you from changing the settings and connect to the Internet in your absence.

Alternative to software techniques is the blocking insulation of equipment with which you access the Internet, modem, router or cables for power and computer connection - from the child in your absence.
