So I am looking to purchase an AirPort Express base station to go along with the MacBook Pro I bought about a week ago. My internet in my house is horribly slow and I wanted to buy this to intensify and speed up my slow connection. I already have a Linksys Wireless N router, and that has an ethernet cable so I was just wondering if the AirPort Express world require one too? Or, could I just set it up and use it wireless-ly? Anyone that is familiar with using AirPort please let me know and all other info about it is appreciated! Thank You
