Asus RT-AC51U - problem with LEDs

Installing and Using OpenWrt
1

Today I installed version 18.06.1 (stable release) on my Asus RT-AC51U - it is working fine (I know that 5GHz isn't supported at all) but except the power-LED no LED is working (especially the wifi-LED).

My configuration is:

config led 'led_wifi'
        option default '0'
        option sysfs 'rt-ac51u:blue:wifi'
        option trigger 'netdev'
        option dev 'wlan0'
        option mode 'tx rx'
        option name 'WIFI'

and I additionaly installed kmod-ledtrig-netdev. Does anyone have an idea why the wifi-LED is not working? If I put the power led into the configuration it flashes on network traffic.

Now supported in snapshot build

Great news :+1: I assume it will be integrated in the next service release.

According the LEDs I checked the values in gpios:

root@OpenWrt:/sys/firmware/devicetree/base/gpio-leds# ls
compatible  name        power       usb         wifi
root@OpenWrt:/sys/firmware/devicetree/base/gpio-leds# cd power
root@OpenWrt:/sys/firmware/devicetree/base/gpio-leds/power# hexdump -C gpios
00000000  00 00 00 10 00 00 00 09  00 00 00 01              |............|
0000000c
root@OpenWrt:/sys/firmware/devicetree/base/gpio-leds/power# cd ..
root@OpenWrt:/sys/firmware/devicetree/base/gpio-leds# cd usb
root@OpenWrt:/sys/firmware/devicetree/base/gpio-leds/usb# hexdump -C gpios
00000000  00 00 00 10 00 00 00 0e  00 00 00 01              |............|
0000000c
root@OpenWrt:/sys/firmware/devicetree/base/gpio-leds/usb# cd ..
root@OpenWrt:/sys/firmware/devicetree/base/gpio-leds# cd wifi
root@OpenWrt:/sys/firmware/devicetree/base/gpio-leds/wifi# hexdump -C gpios
00000000  00 00 00 11 00 00 00 00  00 00 00 01              |............|
0000000c

How can I verify if these are correct? Power is working but USB and Wifi not.

Will this change be included in service release 18.06.2 or in future releases?

Hi Yogi43, did you find a solution meanwhile. I have the same problem.

7

Hi, no I have not found any solution yet.

8

Hi. Same problem here with leds. Did anyone find a solution? Thanks

@githubGF, welcome to the communiuty!

Did you install Snapshot, per the information above?

10

Yes, Snapshot

11

bump is anyone looking into this? Or maybe have some information on how I can fix it myself? This issue still persists in the latest OpenWrt snapshot.

I see someone submitted a bug report also: https://bugs.openwrt.org/index.php?do=details&task_id=2109&pagenum=3

Why is the problem with led not being solved?

I bought an Asus RT-AC51U a few weeks ago and installed version 19.07.5 (unfortunately I don't have the build tag anymore). I had the same problem described here. I didn't try to configure leds and just got used to the situation.

A few moments ago I realized that version 19.07.6 (r11278-8055e38794) was available, and proceeded to install it.

The update process when smoothly and after that I had leds are working as expected. Here's the configuration (actually, the default one):

config led 'led_wifi_led'
	option name 'wifi'
	option sysfs 'rt-ac51u:blue:wifi'
	option trigger 'netdev'
	option mode 'link tx rx'
	option dev 'wlan0'

Thus, updating to version 19.07.6 may solve the same problem in different cases.

Greetings
