Wireless network w/access to the internet from another wireless network

Question

The complex I live in has a wireless network providing internet service to the whole complex. Trouble is, it only allows one device connected to it per apartment. To connect to it from a computer, you have to enter a code via your web browser before you can access the internet, then that device is registered on their system as your one authorized device.

I'd like to set up a wireless network in my apartment that:

• draws its access to the internet from the complex-wide wireless network
• is WPA-protected and firewall-protected, independently of any security that the complex's network offers between it and the outside world

Here's how it looks now:

And here's how I want it to be:

If it's important, I currently have a brand new Linksys N600 router available.

(And this isn't some way to try and cheat the complex's network rules; the manager actually suggested I set up my own local network, she just didn't know how one would do that.)

Answer 1

You need to purchase a router than offers both wireless (Wifi) WAN & LAN simultaneously. My favourite brand is TP-Link, affordable and reliable with a 3 year warranty.
