Why is it so hard to make an 802.11ac Wireless Router with USB 3.0 when clearly an 802.11n router already exists with a USB 3.0 connection? That is exactly why I'm not buying this, yet.
It is a processing bottleneck. Even high end routers with USB2 have a slow 5-10MB/s throughput because the CPUs that they use are slow and merely 'good enough' to get things done. Moving a wireless router up to USB3 may be faster... but it is not going to be anything near what you would expect USB3 to have in performance.
I think the problem with Wireless-AC is that its still in its infancy and everyone knows it. Its hard to justify buying a new router over a Wireless-N with 450mbps when you know that router will be shoveled aside for the next Wireless-AC product in a couple months.
When you do the next review of ac routers, can you do some tests with a mix of adapter protocols? All the reviews I find only have ac routers with ac adapters. I will have PS3 (g), Wii (g?), cell phones (g), tablets (g/n), laptops (g/n/ac), etc. I am worried that this mix of signals will effect the performance of of the router. A mix of 5 GHz n and 5 GHz ac adapters seems most likely to cause problems.
