Hello,
I bought netgear 6400v2 in order to replace useless router from my ISP. ISP router is acting as fiber modem now (I have 1gpbs symetric agreement) and I have successfuly installed DD-WRT build 42914. My boardid: U12H332T30 so I used chk and bin file from here: ftp://ftp.dd-wrt.com/betas/2020/04-17-2020-r42914/netgear-r6400v2otp/
Shortcut Forwarding Engine is on.
Even though ISP router was really crap (can't change anything) I was able to reach 980mbps on cable and around 900 mpbs for WiFi. On netgear I couldn't get higher result then 330mps for cable and 250 for WiFi.
I made additional test with iper3. When I run iperf3 as a server on netgear my PC connected via gigabit cable is giving me 330mbps as max and my laptop no more then 250mpbs so local speed corresponds to the result with speed test over Internet.
When I make iperf3 between laptop (WiFi) and PC (cable) there is also ~250mbps.
Did I choose correct firmware? Or maybe I was wrong when choosing router and netgear 6400 is not able to achive higher speeds with ddwrt?
Especially cable speed is a pitty... Any help will be appriciated. Thanks in advance.

Thanks guys for advices. I do believe that I did "nvram erase && reboot" during first installation as it was stated in manual but I did it once again now. Unfortunately it didn't change anything. Internal speeds are the same. I can imagine that procesor is to weak for 1gbps routing, but internal speeds where frames are just exchanged? The cheapest tplink switch can do switching with 1gpbs speed.
Does it really cost to spend 200$ for 1gbps home router?

It is the WAN<>LAN throughput I am talking about, even the cheapest routers have gigabit switch ports.
Switching is done by the switching fabric of your router, software however can set certain values of the switch but it defaults to auto and should be set at 1 Gb/s but you can always check on the Setup/Switch tab, but I have never seen (and I installed a lot of those) or heard that it was anything else than auto (=1 Gb/s)

So if you have problems with LAN<>LAN check your cables, only yesterday someone was reporting not more than 100 Mb and that was due to a faulty cable
My bad, I didn't check that with dd-wrt the device is slower.
I believe I can exchange 6400 to 7000 in my shop. Is 7000 good enough to handle ~1gbps internal and external speed? Or do I really have to buy 7800?

The R7000 has the same CPU as the R6400v2 (dual core Arm A9 running at 1 GHz) so the speed is the same.
I was able to reach 980mbps on cable and around 900 mpbs for WiFi
may I ask what you have for a WLAN client?
900 mbit over WLAN is impossible with most clients
a 2x2 VHT80 client reaches a maximum of ~600Mbit
LAN <--> LAN Transfer runs purely via the switch and not via the CPU
Every router with a gigabit switch can do ~950Mbit
LAN <--> WLAN
runs again via the CPU
the R7800 manages 600Mbit (I don't have a faster WLAN client but the CPU utilization is already very high)
WAN <--> LAN/WLAN
also runs on the CPU, then there is NAT and/or QoS
the R7800 might manage 400Mbit with QoS (with smoking CPU)
with shortcut forward engine it reaches ~900mbit
well ... even the r7800 doesn't have enough power for a gigabit line
not if you do several things at the same time
LAN / WLAN transfer + multiple WAN / LAN download with QoS etc
you probably need something in the direction of Netgear RAX120 or x86 with core i5
if you want to make full use of a gigabit line with QoS etc

I'm not going to use QoS, just some PAT and configuration inside my local network like static dhcp etc. Router from my ISP didn't give me ability to change anything, but this was speedtest results with it. First was WiFi on 5y old thinkpad, second was with cable on 7y old PC. It will be enough for me if it will be like this.
