Sorry for being technically challenged, but I have what may sound like a stupid question. I'm contemplating getting either the late 2013 MBP 15" or the Mid 2014 MBP 15". I see that for wireless they use 802.11ac Wi-Fi. Does that mean I need to get a new router, or will my old Linksys 802.11a/b/g still work? If my old one will still work with this new computer, will there be a drawback? Thanks for being willing to help this old fart out! ---------- So sorry, but I think I just found the answer....If I understand it correctly, the new computer would still be comparable with my old router. Please let me know if I'm wrong.
