New Build from Tathagata Available

FYI - there's a new build from Tathagata available:

Has anyone tried this out yet?

Hi Peter,

Hi Peter,

Yes, I did on R8000

3 things found so far:

1. WAN issue yet to be fixed - when I rebooting router, I'm getting no WAN IP, but zeros. So using startup script as a workaround

2. For some reason, same place I've got a decent reception at home (front porch) on Kong build - cannot even get connected neither with Macbook nor with android to both 5.8Ghz radios. However, 2.4Ghz works excellent... That is strange

3. Router hung yesterday evening for no reason and had to restart... - need more time to check it out

Hope Tathagata will invest some time to fix those issues

Is there any other build apart of Tathagata or Kong ( from march) on the market?

Steer clear of this build on

Steer clear of this build on Netgear R8000.


There are many radio inconsistencies.  For the most part it is impossible to get both 5Ghz radios working.  


Most of the other functionality seems to work including VLAN's on LAN Ports and such.  Unfortunately for me I need the radio coverage as an AP...

I am trying to compile DD-WRT

I am trying to compile DD-WRT for my Netgear R8000, but I am having some issues compiling Zabbix. 

Can someone please provide any clues to whats failing? 

I have installed all of the requirements and libraries (or at least I think I do). 

OS: openSUSE 13.2 x64 
SVN: 27480 
Router: Netgear R8000 
Toolchain (6/22/15): toolchain-arm_cortex-a9_gcc-4.8-linaro_musl-1.1.5_eabi 
Config: .config_northstar 

Here is a link to the complete console log while I attempt to compile DD-WRT.

In addition, Tathagata would you be able to share your DD-WRT SRC folder? I would love to be able to help you with fixes for the R8000 since there is no love for this router on the DD-WRT forums. Thanks!

I agree - with Tal69 - flash

I agree - with Tal69 - flash with caution.


I flashed my R8000, everything worked super fast, MY accesspoints, hardwired "stuff". But when I connected to any wireless radio on my R8000, I could not access the internet. I could with my access points, no problem, and speed was super fast. Must be some radio issues still.

This version works great for

This version works great for me. If you upgrade to this version, please delete your NVRAM settings correctly. It is important that you do this so that old, bad NVRAM settings from past R8000 builds are cleared and reset. 

The only issue I have is that one of the AC networks, WL0, only works at sub-AC based speeds. WL2 works at 866mpbs.

By deleting my NVRAM settings correctly, my MAC address for my WAN is the correct MAC (not 00:00:00:00:00:02)

Please follow these instructions I posted on the How-To forum:

Flashed the software properly

Flashed the software properly cleared nrvram, etc., issue persists.

Kong's build seems more stable in my environment, no issue with AC speeds.

Works great with R6400. Way

Works great with R6400. Way better and faster than the stock firmware. Thank you!

Hi Tathagata!

Hi Tathagata!

First of all, thanks for your DD-WRT builds for Netgear devices! They worked great for me and I became really interested in creating my own build for experimenting with my devices.


Right now I'm experiencing an issue with the boot (wl.ko loads and causes a kernel panic). I'm trying to figure out the reason, but looks like I got stuck :(

Can you please share your .config file so I could compare contents with one I use? Should be there any modifications to the build process except for the obvious stuff described on the DD-WRT forum?

Thanks a lot again and I really looking forward to feedback :)
