I recently had Verizon fiber optic installed, and they put in a D-Link 624 wireless router. I use a wireless adapter on the second computer. My network is visible to the neighbors, and my question is can I create a secure network, so nearby users can't use my bandwidth (or see my shared files....)?? Wondering if there's a way to include a network key, or some other form of authentication when trying to access my network. I'm kind of a network newbie, so i'm hoping there's an uncomplicated solution. Otherwise, I might have to re-think the wireless option. Thanks!
