Right now, I have 2 of the new apple tvs connected via wireless n to a older apple extreme. The apple extreme has fast Ethernet and not gigabit Ethernet. On craigslist, I have been talking to a guy and he has agreed to sell me a 2tb time capsule for 250. If I buy the time capsule, I would be putting my older extreme on eBay but what I wanted to know was if I would notice any speed increase since the time capsule has gigabit Ethernet. From what I have seen online, it should be faster for wired devices but it is not clear if this carries over for wireless devices too. My iMac has gigabit Ethernet so I wont have any issues there. Thanks to anyone who can help.
