Wireless Performance Explained

Advertised Speeds

This model advertises speeds of 2166.5 mbps on 5Ghz band. However, they are advertising 1024-QAM (which is 25% faster than 256-QAM), which is not part of 802.11ac specification. Since there are no client devices that support this, we can skip these claims. Realistic speeds are listed below!

Advertised Speed of 5Ghz band

Theoretical 802.11ac speed on 5Ghz band (using 80Mhz channel, 256-QAM, 400 ns GI):

  • 4 spatial streams x 433.3 mbps/stream = 1733.2 mbps


This is classified as a “Top-Performer” and therefore the fastest 802.11ac wifi system.


  • WPA2-Personal (128-bit encryption)
  • WPA2-Enterprise (128-bit encryption)
