My main question is 1-"Do I need to have an active internet service to have a closed wireless network running " ? I just want to have a private wireless security camera setup and I do not understand from another forum why everyone thinks I need an active internet service to have my own network . I am Not broadcasting to anything . Nor am I wanting to retrieve any pictures over the net in any way. 2-Does my router send out a signal regardless if I have a active internet service ? 3- Can I send out my own signal from the router ?
