So you have a usb drive attached to the router? I have a seagate 1tb drive attached to 3.0 usb and I get about 5MB/s over samba with ddwrt.

With this signal strength and adapter you should get more than 54M and definitely more than 600KB/s. The settings according to the screenshot look ok.

Only setting I don't see here is, if you disabled wmm, which would explain the problem. If you did not mess with it, then it is most likely an issue in the build.


There is definitely something wrong with a (broadcom?) driver for the R6400.

With original Netgear fw I get much higher rates while copying (see image).

Pitty for dd-wrt, I will have to live with Netgear fw.

Cheers


You are using an unsupported third party build, not ported or tested by a dd-wrt developer.

Our supported builds for netgear units provide the same or better wireless throughput compared to netgear firmware.

With 2.4 Ghz? I only get that when I put dd-wrt R6400 close to my laptop (1 or 2 mtr). Not over bigger distance, then only 1 or 2 MB/s. Must be a problem with handling antenna signals.
I have seen peaks of 10MB/s with Netgear firmware on 2.4Ghz on bigger distance (10 mtr with 1 wall in between).

As Kong wrote there is only third party fw for R6400.

I hope one day there will be native fw support. I can wait.

I just did some recent tests. So I have a Seagate backup plus slim 1tb connected to the USB 3.0 port, I'm 20 feets and I'm 20 feets away from the router on 2.4Ghz (single stream, so 72Mbps link) and I'm getting 5.5 to 6MB/s.

You must be lucky then. I tried every wireless setting to get more speed. Nothing helped. Maybe different hw revision?

According to this wiki it has some Skyworks signal boosters. These are configured in nvram using the pci/1/1 parameters. I will compare the dd-wrt with the Netgear settings. I will attach them both.

Cheers

EDIT: from the original /sbin/routerinfo executable (link to acos_service) I found the ledddown and ledup commands:

Nice to add to your startup script if you want them off.

To enable telnet on original Netgear firmware: http://<routerIP>/debug.htm and enable telnet Wink Maybe this works for other series too.

Thanks for your screenshots (first 2 don't show
and the rest could be smaller !tip!)

Are you really using this?

562mW for 2.4Ghz
668mW for 5Ghz

The default is 71-80 mW! This is almost 10x more power.

After some more testing with dd-wrt on the R6400 I found where the problem is: Country Settings

Only with Country "United States" it performs good (up to 10MB/s over 10 mtr) on 2.4Ghz. "Europe" is less and "Netherlands" where I live is worst.

Can anyone confirm this?

How can we fix this? I want to use CH13.

I just picked up a R6400 and was wondering which to use, Tathagata 27261 or Kong's K3_R6400?

Thanks in advance!

Personally, I would start with a true dd-wrt developer/ed build: http://desipro.de/ddwrt/K3-AC-Arm/dd-wrt.K3_R6400.chk or ftp://ftp.dd-wrt.com/betas/2016/ starting with the folder dated 6/17/2016 and more recent.

How do I flash one of those firmwares??

The one from desipro.de, all I have to do is to hard-reset the router and flash the file?

What about the one from dd-wrt, it has two files. Should I hard-reset and flash the bin file?? The chk is for what??

Limit yourself to not post the same question on different threads or at least wait more than 20 minutes before trying in a different thread. And by what it looks like on the other thread it seems you haven't read a single line from the forum before asking.

I've run without issues on Tathagata 27261 for over 3 months before Kong port his builds so I hardly recommend to get his builds. I'm running on 30645 for over a week now and it's stable.

To go back to stock, can I just flash the netgear firmware?

LOL, are you asking seriously? Yes you can.
