what do i need in order to setup a home wireless network?

bartathalon asked:


i am trying to set up a wireless network at home for me and my brothers and sisters so that when we are in our rooms on our laptops we can still message each other, help each other with homework, and send music and video to each other. This is NOT for internet. mom doesn’t let us have it b/c she says it will side track our studies. but every solution for wireless home networks that i have seen concerns an internet connection. it needs to work in a pretty big house on three floors so i don’t think just creating an ad hoc network between laptops would be suitable. is all we need a powerful wireless router? can it be used to just communicate between laptops?

thanks for any info!!
