I have an old Dell PC Desktop and a Mac laptop. I already have an Wireless router and account connected to the TV in the living room. This allows me to take my laptop anywhere in the house and have wireless internet and this also allows me to be connected to netflix on the TV in the living room. But i have a very old PC desktop in the bedroom and would like to be connected on the internet, mostly for downloading music via limewire. Problem is i can find the wireless option on my Mac laptop (upper left corner) but where do i find that option on my Desktop PC? i dont believe it exsists because it is too old. Is there a wireless software i need? If so what do you suggest? Or instead of limewire any other extremely safe free software for downloading music?
