It's good and easy, had to move the living room where I don't have an additional ethernet plug. My phone has 700Mbps wifi and macbook goes 800Mbps+. This is on 5GHz, however the stick only goes to 250-270Mbps, which I'm ok with for now. But definitely does not reach the 800Mbps advertised.

Small size, decent speed, decent reception.I bought this after I spilled water into my 2012 MacBook Air and crippled the wifi hardware.The driver CD only had Windows software, so most Mac users will have to use a USB stick or an ethernet cable to load the software.There are 2 wifi router units in the house, and the T3U Nano connected easily to one of them, However, the second network didn't appear on the wifi network list, even when within centimetres of the router, and WPS wouldn't connect it.

I'm not a heavy video user, but I was able to watch an ABC iView show from a room 10 metres from the router, going through about 2–3 walls. I can browse easily from 13m away.One issue which I haven't resolved yet it that I'm getting disconnected from the file server if I swap from one wifi network to another, but I expect I'll find the solution in the settings somewhere.
