I have an older ASUS AC66U (Dark Knight) and I get ~60-70 down and about 5-6 up. I'll check it again later. I am going to upgrade my router next to the newest ASUS, now that I stepped up to the faster modem.
I have done some research into the 802.11 standards. Boy, I thought Dell would have some answers about the n and ac. After 30 minutes, back to sq 1.
I finally went on line to a couple of informative web sites.
Discovered that the ac standard only affects, for the better, the 5gH band. One laptop to router has 433 Mbs speed indicated on the local area connection window. And it clocks 120 down
The n standard covers the 2.4gh and 5gH band but it is at 150 to router but max on line speed check is
only around 75-85mbs. AC also has wider bandwidth, higher speed.
Also discovered that the laptop has specs of 1x1, 2x2, etc, n on the wi-fi spec section. That applies to the number of antennas for each band in the laptop that has higher on line speed but perhaps not the connection speed to the wi-fi router.
Next upgrades are ac and subsets.
What a trip to get to the bottom of all this.
I will be looking for those better specs on my next laptop, just because.
