If you have two wireless routers you'll need to create a bridge between the two as routers can only route between two seperate networks otherwise. this is pretty straightford tho but a bit of a pain and something we try to avoid in comms.
My wirless router works fine over large distances, I live in a grpoup of thick walled barn conversions and my friends accross the large courtyard can use my internet connection with no real problems.
I't try a router and see how you get on...some are better than others
