last night I bit the bullet and decided to finally get 802.11ac in our house. Plus, the wife has been complaining about Wi-Fi signal at one end of the house, so I needed something that would deliver a better result than our current stock router.
In addition, because the kids are getting to the point where they will in a couple of years need their own backup systems for their data, I ended up opting for a 3TB Airport Time Capsule. It'll do backup for the wife and kids (I have my own more complex backup system, as I have many terabytes of data), as well as doing 802.11ac and other Wi-Fi around the house etc.
In Sydney the Wi-Fi congestion would have been an issue, and I actually needed two routers for our smallish apartment, but in suburban Canberra signals are few and far between, so we can get away with one.
The upshot is that I will be shortly testing 802.11ac speeds around the house. And, conveniently, I now have an iMac that can support those speeds Timing is everything ...
I'll let you guys know how it goes. Should be able to set it up tonight.
(I know a lot of people will disapprove of the Wi-Fi router choice. I did a lot of research, and the Airport Extreme offered about middle of the road performance. Considering its other backup features, it ended up being worth it).
