|You shouldn't have started a whole new thread. You should have continued with this question in your other thread.|
But, since you have....
If I'm reading this, and the other thread correctly, you already have a SOHO Router in place that provides bother wired and wireless access to the network. You wish to connect a second router to the first via wireless. Is this correct?
If it is, then one of the two routers in question will need to be connected in "bridge" mode and the second router configured with TCP/IP settings that are in the same subnet as the first router.
If this is what you're after, do not come back here and ask us for a detailed guide to doing this. That's what manuals and your brain are for. The chances of any of the regular helpers here having done this setup with the exact equipment you're using is somewhere between slim and nonexistent. So you're either going to have to figure it out yourself, or if you can't, hire a qualified professional to help you.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
