Ok, got an Airport Express g and have had it for about 5 years. Still works, but thinking of getting the Extreme with n since I now have an n card, and my roomie has g. I've reading getting the n with extend range but what about internet connection speed? The internet comes in at 10Mbps goes to cable modem then to Express router. Does it then to go our computers at g speed (54Mbps)?? If yes, then a Extreme n router would sent the internet to my computer at n speeds (300 Mbps). In real life would I feel a difference? My other option would be to have the cable company re-wire the cable modem to where my Mac is located. In that case, would the internet connection leave the cable modem at 1Gbps speed via a CAT6 into my Mac? BTWm how long does a typical Express router lasts? Perhaps I am better off waiting until it simply breaks down in getting a new Extreme n router. Thanks in advance.
