Performance Wireless 802.11ac WIFI

Most enthusiast class motherboards these days have integrated WIFI, and there are so many standards. One of the more interesting ones is Wireless AC AKA 802.11ac and 802.11ad. Motherboards that have such a unit will now be tested here at Guru3D.com Wireless AC draft 802.11ac technology was developed to optimize video streaming experiences. Providing Gigabit Wi-Fi speeds allows content to download faster and large video or music files to sync more quickly. With an increasing number of Wi-Fi devices in the home leading to greater internet consumption, this new wireless draft 802.11ac standard will help you achieve better wireless speeds.

• Our source router is a D-Link DIR-868L compatible with 802.11a, 802.11ac, 802.11b, 802.11g, 802.11n.
• 802.11ac on the Netgear router can achieve a theoretical 1.75Gbps
• The router is located one floor below the office at roughly 10 Meters distance. 
   

Obviously, WIFI is not nearly as fast as wired Ethernet as many factors like error-correction will bring down that speed. This test should give you a rough estimation of what you can expect on both the 2.4 and 5 GHz bands.

Single band 2.4G WIFI performance (average speed)

Single band 5G WIFI performance (average speed)

We can precisely map and measure throughput by measuring multiple times per second during a test run of 60 seconds, this is true sustained throughput. Above, the WIFI throughput over a single 5 GHz connection, which averages out at 178 Mbit/s. We are close to ten meters away from the router and one level higher with a concrete steel reinforced floor.
