Having migrated to the fiber I wanted to exploit the full potential of my box and as the wifi is ready to eat 15% of the performance I chose to take a cable ETHERNET I do pass through a wall for it going to my office. The cable is long, very white, it is the cat.6, the connectors are robust. After nearly a week of use everything works nickel chrome!
I peaked at 96Mbits while with wifi TP-LINK TL-WN822N USB I was at 68Mbits.
My workstation is found in a "hole" where wifi with the internal wifi (normal antenna TP Link) I had virtually no network 3Mbits with this adapter I could reach to pick "68-70Mbits" Remember that Mbits must always be divided by 8 to get the actual theoretical speed: 70/8 = 8.75 Mbytes per second, but in reality I would say we are at max 6megabytes per second.
The adapter is very compact, so perfect really small and lightweight for carrying in your pocket or bag. The USB cable is really stiff and high quality!
I do not know what use WPS, since I have not installed the utility directly but the drivers I think that walking with the utility to allow connection "SECURE".
Only point of criticism: It's not perfect, but I do not see, for the price of your investment pays 12 to 100%.
I would recommend it to a friend!
