“do you set up wifi for computers? I have a desk top computer from my cousin. It has a lot of programs, etc., and I would like to use it fori Internet searches and research as well as email and social network functions. I don't know what year it is, but since I am not able to find a brand name, and he had the machine for awhile, I can't say what it is or the memory size or any other specific guidelines. I can tell you that I have a Samsung tablet that currently works on wifi, and someone gave me a doohickie that's supposed to be a wifi adapter for the pc. So, can you help me?”
