Do u want 2 be sharing files&document btw d 2 pc without internet or u want d 2 pc to be on internet? if its sharing ur documents,file&printer without internet btw d 2pc then u must get a cross-cable. But if u want d 2 pc on internet then u hv to configure router so tht it serve as ur gateway, by setting ip given by ur ISP as ur default gateway&create and ip for d 2 pc. for example
COMPUTER 1

COMPUTER 2
