Eh?
The guy mentioned that he switched from using the built-in antenna on his laptop to a honking external antenna and now gets 720mbit/s performance anywhere in his house. That's quite constructive. I guess the only way it could get more constructive is if he mentioned the model of hardware involved... but I expect that you'd get similar results with any AP capable of 720mbit/s transfer to a single client. If your AP is fast enough, then it's all about SNR.
>but I expect that you'd get similar results with any AP capable of 720mbit/s transfer to a single client.
One should expect that, but almost no one uses wireless that way. If you have just a single client the most efficient method is to run a cat5 cable and get 1000mbit/s at a much lower cost than putting in expensive AC equipment, barring an expensive engineering issue of making a cable reach that place. The problem with wireless is everybody has to play nice and be able to see each other or it quickly falls to the 20% actual usable bandwidth rather quickly. Do you have neighbors with a wide bandwidth AC router and healthy streaming video habit? Don't expect to get max data transfer rates. Do you have lots of portable devices, especially cell phones that like to go into low power mode, or get set in places where they can reach the router but become hidden nodes to other clients in the network?
