I'm not sure if they exist but what I'm looking for is a way to convert a network card that was desined to work with a wired network to one that will work with a wirless network. I've looked for an attena that I could connect to the network card but I have been unable to find anything. Perferibly I would like something that is non-manufacture specfic since the group of computers I need to do this with came with network cards and I don't know who there manufacture is.
