How to add an extra router to connect a DS to the internet? - the internet opticianscode

I already have a wireless network in my house, but a WAP instead of WEP key, so you can not come through it together, but I wonder if I could make a 2 plug the router is connected to a WAP key or keyless could then connect to the Internet, if the current connection. How can I do?

Thanks in advance!
