An internet-less wireless local network: I'm looking to build a simple wireless local network comprised of the following: 1. A wireless N router or access point 2. One or more PCs wired to the router that will act as NAS 3. A tablet that will allow me to access and work with the files anywhere in the office. [I have a nice 64G Toshiba already] Wired/Wireless security are key here. I do not want the router or any wired PC to be connected to the internet. No Internet Access via this router! Can a router work like this without being connected to the internet? the wireless router should only allow specific devices to connect to it (i.e. only my tablet) Can I specify on router settings what Mac Addresses are allowed to connect? I want a fast connection so I do not necessarily want to encrypt all wireless traffic. Any ideas on an Android App that will best enable me to access shared files on a local network? Thanks for sharing your expertise!
