Anecdote time (but in a more simple case): Like 15 years ago, I got tired of too many wires at home and I bought a wifi pci for my desktop computer. The problem was that the antenna was in the back, so the computer was blockink the signal. I bough a SMA extension to be able to put the antena on top of the computer and it worked like a charm. Best $5 ever.
