Hello, I am sure this has been asked but I couldn't find any threads (maybe my searching sucks!). I am in the market for an Apple Airport Extreme (or Netgear WNDR3800/4500, but I dislike Netgear). Everyone says that the 5th gen is much more powerful, etc. My house is not very big, consisting of a basement and an upstairs (router is placed in basement). I just want/need a good router with gigabit ethernet ports and a decent WiFi signal, to cover my house. It seems the 5th gen is much mower powerful at transmitting WiFi signal, but I'm not sure if i'll need that. The 4th I could pick up for much cheaper. Is there any other real benefit for getting the 5th vs the 4th?
