Version 2 GL-USB150 led internet and vpn status indicator

credits to original script modified from keolafu for ar750

Here’s what it does GL-USB150 has two lights power and wwan.
by default the power stays on and wwan just flashes with traffic.
Here is what the scripts below change them too

power button is blinking when there is no internet connectivity and solid when internet is up

wlan button is solid when you are connected to openvpn with a default route of 10.8.x.x address and blinking when it is connected to wireguard with a default route of 10.0.x.x address.

  1. goto http://192.168.8.1/cgi-bin/luci/admin/system/leds and uncheck “default” and set both triggers to “none”

  2. grab a beer

    • upload the two scripts below (e.g. to /usr/bin/). If sftp does not work you can use in your ssh console: cat > full-path-and-filename and simply copy and paste the content of the script (use ctrl-d to get back to your prompt).:point_up: Be careful, the cat > command overwrites everything of the file. Check better twice the correct spelling of the filename before you enter into the command :wink:
    • chmod u+x full-path-and-filename
    • now you can check the scripts by calling them without arguments.
    • to let them call frequently by the system add the cron configuration with the glinet admin web tool or crontab -e

so I revisited these scripts and noticed a change where

vpn_led=/sys/devices/platform/leds-gpio/leds/gl-usb150:green:wlan/brightness
vpn_trig=/sys/devices/platform/leds-gpio/leds/gl-usb150:green:wlan/trigger

is now called

vpn_led=/sys/devices/platform/leds/leds/gl-usb150:orange:wlan/brightness
vpn_trig=/sys/devices/platform/leds/leds/gl-usb150:orange:wlan/trigger

and also you must go into http://192.168.22.1/cgi-bin/luci/admin/system/leds

and change ath9k-phy0 to gl-usb150:orange:wlan

this may be something different in the 3.2-19.07.7 or perhaps a gl-enhancement :wink: (we never call it a bug or a mistake to the good guys) both leds on the device are physically green and I don’t remember what version I wrote this for. if someone could please verify if theirs is green or orange for wlan that has done a fresh install. I believe mine was an upgrade.

and a quick note that */1 means every minute in the crontab so */5 means every five minutes. and one last note if your wireguard tunnel is something other than 10.0.x.x or openvpn tunnel is something other than 10.8.x.x you can change the the two instances of ‘’’

if [ "$first_hop" == "10.8" ] && [ "$enabled" == "1" ];then

to 

if [ "$first_hop" == "10.8" ] || [ "$enabled" == "1" ];then

and

elif [ "$first_hop" == "10.0" ] && [ "$wgenabled" == "1" ]; then

to

elif [ "$first_hop" == "10.0" ] || [ "$wgenabled" == "1" ]; then
