Aironet 1562E Poor download speed 802.11ac

Hi. I`ve setup 1562E on wlc 5500, i connect to AP 866.7-780Mbps. But the transfer speed is awful.

Download speed vary from 2-7mb/s, when working in 802.11n i get better download speeds 12-14 mb/s

Transmit is somewhere around 20 mb/s

Re: Aironet 1562E Poor download speed 802.11ac

What is the wireless NIC that is doing this so-called "speed test" and what wireless driver is the wireless NIC loaded with?
Provide the complete model number of the wireless NIC.
What firmware is the WLC running on?
