Although D-Link did fairly well on the 5GHz band, its 802.11ac performance failed to match up to ASUS which blazed its way across the tested distances between 2 to 25 meters. The DIR-865L netted a peak average throughput of 138Mbps at close range, with a similar result of 135.341Mbps with WPA2-AES applied. Its downlink speed dipped slightly to 112.699Mbps when the range is extended to 10 meters, and 120.41Mbps at 25 meters. That's not too shoddy, considering it outdid Netgear's R6300 contender at every checkpoint. However, the DIR-865L pales in comparison to the unforgiving ASUS RT-AC66U, which maintained a steady throughput of 162Mbps (give or take) for all ranges. Transfer time for a 1GB file took 38 seconds, versus ASUS' timing of 32 seconds. Sadly, D-Link's average uplink figures were less impressive compared to its downlink results. It peaked at 108Mbps at 2 meters, with a final data rate of 89Mbps at 25 meters. If we had to nitpick, these numbers are closer to that of an 802.11n router rather than that of a souped-up AC alternative. It's also interesting to note that all three models are equipped with Broadcom wireless chipsets, which suggests ASUS' deployment  of external antennas might have something to do with its noteworthy 802.11ac performances.
