Using more than one router?

Ok I am going to be moving soon, to a much bigger house where the one wireless router will be at one end of the house, and my pc at the other which is on wireless at the moment. I have searched but I have a hard time understanding alot of this networking stuff. I'll try to explain what I would like to do if it's possible.

PC one is downstairs, wired to the router off the cable modem. Is it possible to wire my pc upstairs across the house to another router and use that as wireless instead of just using the card in my pc? If that can work I would like to do that instead, because I just bought another router. Nothing wrong with my old one, damn cable co. shut it off here when we had it turned on at the new house so I thought it was the router before I checked with them.

I have 2 Linksys routers by the way.

Please treat me as noob as possible here, I am not very good with networking. Thanks in advance for all the advice you can provide.

 

That is what wireless is for. But if you don't have a wireless network card in the PC & don't want to add one (either internally or USB externally) you need to create a bridge. You may want to google "wireless bridge linksys model"
