I have a linkseys wireless B - USB adapter for my new desktop computer but I dont have the instalation disk for it. Should I bother finding the drivers and what not or should I just get a new and more advanced one because it was made in 2005 and Im wondering if it might be outdated, Also, my computer is in my room on the third floor and my router is in the basement so they are kind of far away and I dont know if the current wireless adapter will be strong enough for a good signal.
