My son is at that age when he wants to explore the internet. We have a family PC he uses that is filtered for content. But he wants a laptop to do school work on, and needs wireless access to our home network to print and also use the network storage device. That is no problem, but we want to block any internet access that he may be able to connect to at a library, restaurant, coffee shop etc. Can I set up the laptop to allow only wireless home network access and not any internet access?
