Okay, So I purchased an Airport Extreme Base Station in 2008. This makes it either a 2nd, or possible first generation model (after the round versions) I am wondering what the current (5th gen) or Time Capsule (4th gen) would do for my network. My current setup does not extend to my whole house so I had to purchase an Airport Express extender. My question is: do the newer generations have substantially faster wifi access or do they have much greater range? I am debating a new Time Capsule purchase for backup AND updated wifi base station over another hard drive only expansion option... ---------- I noticed in the specs that my base station has only SINGLE 2.4Ghz or 5Ghz. And it sets it at the lowest device, so I am probably running 2.4Ghz Radio. The new ones do Dual Band (both radio frequencies) so I wonder if this would make a difference since I have: Early 2009 Mac Mini, iPhone 5, iPhone 4s, iPad original, iPad 3rd, and a Dell Laptop PC all using my wireless network.
