I live in apt complex where the wireless Internet is built into the price. I want to connect a router to the wireless via the WAN port and then have my computers on a separate LAN than the rest of the apartment complex. Do they make a router that will take wireless in and out?
The issue with this is that you will not be able to connect to the WAN (the Internet) if you do that. You can put on a wifi extender but you will still be on the same IP range and settings as the rest of the computers.
You can't take a router, and configure it for your own settings and connect to the internet through a second router. Remember that the router will give out a NATed IP range to the internal network, which is what your router will pick up on it's WAN port, not the ISP settings.
the other thing would be to use a router that can be upgraded with DD-WRT firmware, program the wireless lan port via Virtual LAN to become a WAN port; however, this will still only give you LAN ports to connect to and no wifi.
