mystic @ problem.

mystic bought himself yesterday a new pc. So he already had a pc(his dad's) with working internet but he wants internet on his new pc too. He's using wireless (dad's & new) But on his dad's its working and on his it's not. Already tried several things but nothing worked out. It's saying: "cant find network adress" or "Not able 2 connect " Can somebody tell him step for step how 2 setup that new wireless connection 2 his router?? thanks in advance.! <3

mystic will play 1o1 vs u if u fix this!
