To test the WIFI Performance of ASUS DSL-AC68U we used LAN Speed Test (Lite) installed on ASUS X99 Deluxe test-bench and Sony Laptop connected directly to router Ethernet port via a patch cable. This testing was done on the 2.4GHz and 5GHz bands at three different locations with Router Laptop and test-bench apart at :

  • Short – approx. 3m distance
  • Medium – approx. 10m distance
  • Long - approx 25m distance (for this took router and laptop to a neighbors building)

Power Consumption

Wattage reading as per displayed by APC Pro 1000VA (Model no. BR1000G-IN) UPS.
