video game routing at its cheapest

I've got a ps2 that I want to route a cable internet connection to via wireless to my basement. The only problem is I am cheap and dont want to buy a 300 dollars worth of gaming routers and adaptors. I need a cheap way to accomplish my task. First off i would like to say that i found a decent speed dsl router/modem just sitting in my basement unused (http://www.walmart.com/catalog/product.do?product_id=5703842) and i was wondering if i could just use the router feature even though my connection is cable based. I already have a cable modem. Also, i was wondering, since most adaptors are very expensive for what little work they do i was wondering if i could buy a cheaper linksys router for 20 dollars less then most good gaming adaptors and use it as an adaptor rather then as a router.

If you guys have any better suggestions as to how to do this then shout out cause i am up for anything effective and cheap. The only thing I wont do is wire it because that is too much construction work to do to my house.

thanks

 

You can spend less than $50 and get a very good ethernet wired router frm Linksys.
