Hi,

DD-WRT v3.0-r43099 std (05/09/20)

Anyone have Night Mode working on their R6700v3 by chance?

Netgear AC1750 R6700v3:

https://wiki.dd-wrt.com/wiki/index.php/Netgear_R6700v3

(nearly identical to r6400v2)

https://wiki.dd-wrt.com/wiki/index.php/Netgear_R6400v2

I've looked over a few posts that may help lead the way, although they are for different routers:

For the R7000:

I've had some success with the following:

Code:

for i in 1 2 8 9 12 13 ; do gpio enable $i; done
for i in 10 11 ; do gpio disable $i ; done

I'll have to play around with the numbers a bit, however, as some are being shut off, whereas others are not.

I get an error with this:

Code:

for i in 1 2 8 9 12 13 ; do gpio enable $i; done
for i in 10 11 ; do gpio disable $i ; done
et robowr 0x0 0x16 0x0

/tmp/custom.sh: line 3: et: not found

This is a work in progress. I'll update again after more discovery and testing.

Lights in order from left to right based on router itself

Code:

GPIO # LED    Notes
0
1    Power    Enable/Disable LED (gpio enable 1 turns led off)
2    Power    Toggle Led Coler (White/Amber)
3
4
5    Reset    Full Reset (gpio disable 5 resets router - or maybe it was enable, I forget now; requires user/password update; not an led, obviously)
6    Internet Enable/Disable Led (gpio enable 6 turns led off)
7    Internet Toggle Led Color (White/Amber)

?    Ethernet 1
?    Ethernet 2
?    Ethernet 3
?    Ethernet 4

8    2.4 GHz    Enable/Disable Led (gpio enable 8 turns led off)
9    5 GHz    Enable/Disable Led (gpio enable 9 turns led off)
12    Guest WiFi Enable/Disable Led (gpio enable 12 turns led off)
13    USB 3.0    Enable/Disable Led (gpio enable 13 turns led off)
10    WiFi On/Off Enable/Disable Led (gpio disable 10 turns led off)
11    WPS       Enable/Disable Led (gpio disable 11 turns led off)

Put this in your startup script on the Administration / Commands tab

Save and reboot.

Cheers

Thanks jxm!

I submitted my last before I saw your post. Going to give this a go.

Okay, This is what's working so far, based on my above discovery:

Code:

#!/bin/sh
#
for i in 1 6 8 9 12 13 ; do gpio enable $i ; done
for i in 10 11 ; do gpio disable $i ; done

The following still gives me errors:

Code:

et robowr 0x0 0x18 0x1ff
et robowr 0x0 0x18 0x0
et robowr 0x0 0x1a 0x0
et robowr 0x0 0x16 0x0

I assume those are for the Eth. ports 1-4? I've yet to get those turned off.

@jxm enable 17, 18 and disable 14, 15 did nothing.

Since et wasn't included in the build I'm using (and why my initial error), I grabbed it from here:

https://forum.dd-wrt.com/phpBB2/viewtopic.php?p=1181821 (I'm attaching a copy for convenience and future reference.)

Initially I tried installing et to /tmp but, it was gone on reboot so, I turned on and cleaned JFFS and rebooted per the following instructions (I had plenty of space)

https://wiki.dd-wrt.com/wiki/index.php/JFFS_File_System#Directions_for_.28normal.29_users:_using_Web-GUI_Interface

After wget the et file into the /jffs directory and chmod +x it and setting the path in the startup script etc. all seems to be working well:

Code:

#!/bin/sh
#
for i in 1 6 8 9 12 13 ; do gpio enable $i ; done
for i in 10 11 ; do gpio disable $i ; done
/jffs/et robowr 0x0 0x18 0x1ff
/jffs/et robowr 0x0 0x18 0x0
/jffs/et robowr 0x0 0x1a 0x0
/jffs/et robowr 0x0 0x16 0x0

Posted: Sun Aug 09, 2020 3:26 Post subject: LAN1 light neved goes OFF

Connect your ethernet cable to LAN connection 1. Let the light be ON indicating that there is a connection.

Then run your commands.Does the LAN1 LED go off?
Have you checked this? (Because when no cable is connected, this light is naturally off, and the commands will seem to work.)

This light never goes off - even after running the commands you posted and that is my specific problem for past 2 years. Not a big problem, but something I am yet to see a solution for.

And if you are using Kong's dd-wrt, et is included by default.

I think you're right about Lan Port 1. It's orange and flashing when something is plugged in, where as the other 3 are turned off.

Can I assume this is the line for the first lan port?

Code:

/jffs/et robowr 0x0 0x18 0x1ff

Perhaps it's not correct? Would be nice to have it turned off as well but, currently I'm only using three ports, so I lucked out.

I'm using DD-WRT v3.0-r43099 std (05/09/20) and if I remember correctly, why I had to add et manually.

I recently updated to the latest build on my r6700v3 and had some issues getting the Ethernet leds to turn off at all, so I did some testing and I think I have it working really well now. Including the shut off of Ethernet Port 1 Led too, which is awesome! - I can use that port again lol.

Anyway, here is a gist of my discovery, including comments (which gives more context to what I'm writing here)

https://gist.github.com/Natetronn/1dbfaa6831796440bb8c2c6da14455fa

---

Changes for the et robowr commands:

What I was using in the past looked like the following, although Eth port 1 led never shut off:

Code:

/jffs/et robowr 0x0 0x18 0x1ff
/jffs/et robowr 0x0 0x18 0x0
/jffs/et robowr 0x0 0x1a 0x0
/jffs/et robowr 0x0 0x16 0x0

For this latest build (netgear-r6700v3-webflash-11-05-2021-r47618.bin) I'm now only using these two lines like so, and Eth Port 1 shuts off (hurray!):

Code:

/jffs/et robowr 0x0 0x18 0x0
/jffs/et robowr 0x0 0x1a 0x0

Note: /jffs/et robowr 0x0 0x18 0x0 - makes all 4 eth ports start to quickly flash white and this /jffs/et robowr 0x0 0x1a 0x0 turned them all off, including eth port 1.

Also note: this new two line method may work on the previous builds (I was on netgear-r6700v3-webflash-05-09-2020-r43099.bin previously) but, I didn't test it and can't say.

gpio changes:

Things that change between the above discoveries listed in this thread and this new gist that I'm linking to now...

Either the above lists were wrong and this new gist was right or stuff got flipped at some point between builds.

6 and 7 got flipped (7 now used in place of 6 in the for loop)
8 and 9 got flipped (no actual change to the for loops)
10 and 11 got flipped (no actual change to the for loop)

Anyway, the gist I linked to above has the updated commands for those looking for full night mode.

Some additional information might be found here: https://github.com/mirror/dd-wrt/blob/bacd5befcbbd942b77d6e1e791fc8cfdd19edbb4/src/router/libutils/libutils/ledconfig.c "ledconfig.c" is in charge for mapping LEDs in DD-WRT. Maybe useful?

For the r6700v3 (r6400 and r6400v2), these lines in particular: https://github.com/mirror/dd-wrt/blob/bacd5befcbbd942b77d6e1e791fc8cfdd19edbb4/src/router/libutils/libutils/ledconfig.c#L1568-L1581 I'm not familiar with ledconfig.c, how it works or what it does. Are those cfg's now available to run from the terminal or something?

This config describes how a gpio has to be set to enable or disable a LED e.g To disable the Power LED on my R7800 I have to issue: gpio disable 0 to enable it again, I issue gpio enable 0.

I see. I guess I assumed gpio itself was all that was needed for the commands to work, similar to how I assumed et and its command were working.

This also works for the R7000 as long as you download et and place it in /jffs.
