I figured out how to have the router boot with LED disabled; thought it might help others to post my step by step SSH in; log-in as root using webGUI password cd /usr/bin (change directory to where you will create your script, in my case to disable front LED) vi led\_off (edit a new file named led\_off) click a (append at current location) paste following #stop glinet control /etc/init.d/led stop /etc/init.d/led disable hit Esc, then :wq Enter (write file and exit vi editor) chmod +x led\_disable (make it executable) cd /etc vi rc\_local (edit rc\_local to add a call to your new script at boot) use arrows to move to the end of the last line of the file hit a (append at current location) Hit Enter 2x (move down and leave a blank line paste /usr/bin/led\_off & hit Esc, then :wq Enter (write file and exit vi editor) Reboot, and enjoy! ---

@alzhao can we get some more user friendly instructions as to how to use the i2cset instructions e.g. how to dim the led permanently ? ---

Just edit ```auto /usr/bin/mt1300_led ``` and modify the two lines. Change the last value to smaller number ```auto i2cset -f -y 0 0x30 0x06 0x3f i2cset -f -y 0 0x30 0x07 0x7f ``` ---

This is very helpful. But could we just have a setting in the firmware to turn off the light? Tape works, too. ---

Had errors in initial post and adding a bit of detail SSH in – I use Putty on Win10 (select 192.168.8.1 port 22 – hit enter) Log in using WebGUI credentials cd /usr/bin (change directory to where you will create your script, in my case to disable front LED) vi led\_off (edit a new file named led\_off) click a (append at current location) paste following #stop glinet control /etc/init.d/led stop /etc/init.d/led disable hit Esc, then :wq Enter (write file and exit vi editor) chmod +x led\_off (make it executable) cd /etc vi rc.local (edit rc.local to add a call to your new script at boot) use arrows to move to the end of the last line of the file hit a (append at current location) Hit Enter 2x (move down and leave a blank line paste /usr/bin/led\_off & hit Esc, then :wq Enter (write file and exit vi editor) Reboot, and enjoy! ---

You can turn the light off by pressing on the button very briefly ---

Hi, i bought this router to replace the GL-MT300N-V2, but the old one support the led costumization for example to turn on the middle ligh only if vpn is connected. Its possible have the same thing on this one? For example only show white light if vpn is connected? I already configurated the internet kill switch, but when the vpn drop the ligh not change to blue (no internet light) Thank you for your attention ---

> [@FMorgas](#): > > Its possible have the same thing on this one? For example only show white light if vpn is connected? Now, with VPN it is breathing white. Withut vpn it is solid white. Of course you can configure as you want but it is more complicated. You should find your script and then control the LED as in this instructions. ---

Hi thank you for your attention. I already tested and the light doesnt change… With VPN → solid white Without VPN → solid white There is some update/configuration that needs to be done for breathing white when VPN is on? ---

Maybe I misunderstand. The definition of the LED, does not show VPN status. Sorry for confusing. [Next page](https://forum.gl-inet.com/t/gl-mt1300-led-control-instructions/13338.md?page=2)
