Ok, I'm a little confused (you know me). I have Airport 9.52, according to my computer. I do have problems sometimes not picking up signals when others show a strong signal. Do the wi-fi cards just slip in and work, or is there a lot of setup? Is the Airport version I have the same as everyone else's with a 500 Ti?
