N/AC- or AC/N-Mixed; but it would help to see basic and advanced wireless settings that you've set to see if something (else) is not optimal. _________________ "The woods are lovely, dark and deep,

The 1300Mbps is theoretical and mainly advertising. It may be the maximum throughput for several wireless devices. With my RAX45 router (Netgear firmware) the maximum wireless is about 650Mbps. With my R7000P (DD-WRT) the maximum is over 600Mbps. Mu setup is SFE and CFT + FA. On my setup SFE works better CFA seems initially better but after several minutes it slows down to speeds less than SFE.
This is the maximum link / PHY rate for 80Mhz channel width with 256-QAM modulation and 3 spatial streams.
The maximum possible throughput is ~70% of this.
And of course a router with 1Gbit LAN ports can't reach over 1Gbit.
So if we assume a PHY rate of 1300Mbit then the radios can't reach more than ~910Mbit of real throughput - and that as said only to clients that have 3 antennas and can handle 3 data streams.
For clients with 2 antennas the maximum throughput is ~610Mbit.
The maximum link / PHY rate is as said significantly higher than what can be transmitted as payload.
400Mbit is a strange number in any case
Either you didn't tell us the rate correctly or your router is set to 40Mhz and has only 2 antennas

I've got my R6700 V3 operating at 950Mbps Wired.
Now, the question is:
How can I get my 5Ghz radio rate above 400Mbits/s (400Mbps)?
I can't seem to get the 1300Mbps possible with this router.
I'm set to 802.11ac only.
Have tried frame burst, etc.
Can't get the rate in the Status -> Wireless above 400Mbps
Ok so you’re talking about the wireless link, i faced this issue with iPhone XS and R6700v3. Now the R6700v3 is at a remote location so i cannot test with my new phone regularly. Is this 400mbps link for all of your devices? What type of clients?
The other client is a Samsung S21 Ultra, according to Samsung's site here: https://www.samsung.com/global/galaxy/galaxy-s21-5g/specs/
Wi-Fi 802.11 a/b/g/n/ac/ax 2.4G+5GHz+6GHz, HE160, MIMO,
1024-QAM Up to 2.4Gbps Download / Up to 2.4Gbps Upload
...so not sure how many spacial streams here because I'm not sure which bands the 1024-QAM applies to, etc.
My guess is that 2x2 vs. the router's 3x3 has some kind of least common denominator.

My suggestion is to use a WiFi analyzer app which is available for your smartphone. You can also try a short preamble. Take the DD-WRT off of auto and select a channel which has minimal interference from your neighbors.
