2021.08 R6250 LED are Amber

[Yick Xie]

Power & Internet LED both are amber, and “led diag on/off” make no difference. They are green on the stock firmware.

how do you use your router? AP mode only?

try led “white” → for WAN LED

‌

check your router for supported LEDs

root@R7000:/tmp/home/root# led
led <wlan/diag/white/dmz/aoss/bridge/usb/usb3/5g> <on/off> [...]
root@R7000:/tmp/home/root#

‌

Basic setup: PPPoe + WIFI 2.4/5 + CTF .

Led white on/off actually turns Internet led on/off, while aoss does logo. But diag changes nothing.

root@R6250:/tmp/home/root# led
led <wlan/diag/white/aoss/usb> <on/off> [...]
root@R6250:/tmp/home/root#

please use led cmd for every available led and report back what colors you see for each mode (On or Off). Will be helpful to see if something is wrong in our led table. thx

led wlan on → result

led wlan off → result

….

[Yick Xie]

led wlan on → WLAN blue

led wlan off → WLAN off

led white on → WAN blinking amber

led white off → WAN off

led aoss on → LOGO white

led aoss on → LOGO off

led usb on → USB blue

led usb off → USB off

Actually as described in manual https://www.downloads.netgear.com/files/GDC/R6250/R6250_UM_17July2013.pdf

Power led shall turn from solid amber to soild green once the router is ready.

WAN led shall turn from solid amber to solid green once the Internet is ready.

After I double-checked, led diag on → off indeed changed “Power led“ dim amber → brighter yellow. Because it is very difficult to tell difference, I cannt say that as for blinking WAN led.

‌

In addition, can I just stop WAN led from blinking?

[M_ars]

I do not know the command or setting for blinking control for LED (Netgear default setup) . There is no datasheet.

But if i understand you right. All LEDs do something, including Diag-LED. Maybe you can find the disable LED blinking cmd at google / dd wrt / or other router forums ?

I have seen using ps aux - a blink command/process running

blink eth1 wlan 10 8192

blink eth2 5g 10 8192

Unclear if this may/not be something useful. This is barely all I know:

root@r7000:/tmp/home/root# blink --help
usage: blink interface led rate threshold

[Yick Xie]

Thank you for your answers.

I guess blinking could be controlled by the blob driver. Some of them may be loaded from CFE, e.g. “ledbh“, and values are defined in wlioctl.h. However I don’t know how they are mapped in the FT led table.

In my router, “nvram show | grep ledbh” shows

pci/1/1/ledbh12=11
pci/1/1/ledbh0=255
pci/1/1/ledbh1=255
pci/1/1/ledbh2=255
pci/1/1/ledbh3=131

So here “ledbh3”=131=0x83, means WL_LED_AL_MASK | WL_LED_RADIO; 255 means GPIO is not available.

you can turn off or on wireless lan blinking via GUI (see admin-buttons.asp). WAN blinking control is not available via GUI

I do not see the issue? (except no WAN blinking control → enhancement)

I think can be closed now
