You need a client utilizing at least tri band wireless ac for your theoretical 1300 Mbps
dual band ac caps out at the theoretical 866 Mbps
(most laptop's, pc's & only 1 smartphone that I know of..SGS5)
single band ac caps out at the theoretical 400 Mbps
(most smartphone's that advertise ac.. sales gimmick)
This has all been well documented all over the internet for years now
So quick answer is get a better/more capable wireless card for your client
Though I suggest doing a little more research than you've done here before purchase
They are not all created equal and without issues
Nor is the real word speed close to the theoretical _________________ Location 1

I realize than most laptop cards and devices are dual band, I meant if any configuration needed to be done on the r6300v2 to take advantage of the three bands.
Under his settings he can select vht80 +80 I can't do that, I can only select vht80. I realize his router is the r7000 but they both claim 1300 mbs over 5ghz.
It is “streams” we’re talking about in this case, and not “bands”.
“Bands” is about Frequency band, i.e., 2.4GHz band, 5GHz band. If it has both, it is “dual-band”.
Streams refers to the number of streams possible for each band. This applies to Transmit (TX) and Receive (RX). The easiest way to validate for consumer class devices is to check how many antennae the device contains. So if you have 3 antennae, you have 3 multi-spatial streams. (3x3 [3TX x 3RX]) If you have two antennae, then you have two streams. (2x2) If you have 4 antennae on a consumer Wireless Router, you likely have a wave II 802.11ac device with 4 multi-spatial streams (4x4) and MU-MIMO. (R7800, etc.)
Channel width is how fat the pipe is for each stream...20MHz, 40MHz, 80MHz, 160MHz The bigger the channel width, the more data that can be pumped thru.
Only wave II 802.11ac devices can do 160MHz (contiguous) or 80+80 (non-contiguous) channel width. (There are not many clients that can do 160MHz/80+80 yet anyway.) An example of a Wave II 802.11ac router is the NETGEAR R7800 and R7500. R7000 is a Broadcom 802.11ac Wave 1 device, and cannot do 160Mhz/80+80. It is also a 3x3 multi-spatial stream device.
Finally, the numbers used for Wireless “bandwidth” are complete BS. They actually represent max PHY Link rate. PHY Link and actual throughput are not the same, and actual throughput will always be less...often much less. Anyway, the max PHY Link rates quoted above are for 802.11ac 5GHz 80MHz Channel width and various multi-spatial streams (3x3, 2x2, 1x1), and are correct.

On 802.11ac vht80 (channel width of 80 MHz) you theoretically can get 433Mb/s, tri stream (3 anntennas) 3 times 433 = 1300 Mb/s
But as others said that is pure theoretical even with a 3 antenna (stream) client you will not get more than around 800Mb/s actual throughput.
With a single stream client with 80 Mhz bandwith you are stuck at around 300 Mb/s actual throughput in optimal circumstances.
802.11n (2,4 GHz) has theoretically 72 Mb/s per stream per 20 MHz bandwith for 40 MHz bandwith it is 150 Mb/s (40 MHz is the maximum bandwith for 802.11n).
Theoretically 4 streams are possible thus theoretically 600 Mb/s is possiblle, in reality around 450 Mb/s.
But on a client with one stream (antenna) and 40 MHz channel width it will be actual around 100 Mb/s
So if your router is advertised as ac 1750 it is a 3 stream (antenna) router with theoretically 1300 Mb/s on 802.11ac and 450 Mb/s on 802.11n together = 1750 MB/s
