My NETGEAR WNR854T died and I am looking for a replacement. I do a lot of online gaming and HD video streaming, and have several wired and wireless devices in the home network. I also have been thinking of getting a shared backup hard drive. I started looking at the NETGEAR WNDR3700 unit, but there are a lot of people complaining about dropped connections. So, I am now looking for an Apple Airport Extreme. During my research, I found also the Apple Time Capsule. Is there any advantage to getting the Time Capsule? Or should the Airport Extreme be better by adding any external hard drive to the USB port? Also, is model number MC340LL/A the correct one for the Apple Airport Extreme? Thanks!
