When it comes to wireless performance we used LAN Speed Test to check the performance of the included the included $699.00 shipped. This is one of Intel’s latest 802.11agn Wi-Fi and Bluetooth cards for mainstream applications. The card is socketed and replaceable, so you could always change it out down the road with an 802.11ac card if that was something you were interested in doing. This card is a dual-band 2×2 wireless card (TX/RX Streams), so it has a peak theoretical peak speed rating of 300 Mbps. It also supports Bluetooth 4.0 devices as well as Intel Wireless Display (WiDi)!
We used a desktop with Gigabit Ethernet to run LAN Speed Server that was hard connected to the ASUS RT-AC68U 802.11AC wireless router on the 2.4GHz band and moved it 15-feet away from the NUC test machine to check out performance with both 1MB and 100MB packets. We ran LAN Speed Test and looked at performance with 1MB and 100MB files on the 5GHz band.
On the 1MB packet size test we found 89Mbps (11.1MB/s) average write speeds and 114Mbps (14.25MB/s) average read speeds. With the larger 100MB packets the performance jumped up to 148Mbps (18.5MB/s) average write speeds and 215Mbps (26.88MB/s) average read speeds. Not bad performance for 802.11n, but certainly not as good as one would get with an 802.11ac solution.
