Hi,

Does anybody know GPIO combination for RT-AC88U?
How many GPIO there?
Is somewhere official list of them?
Especially I am interested in how to enable/disable GREEN LED for WAN, because WAN has RED and GREEN LEDs. I suppose it can be right combination of two GPIO.

By experimental way I found these:

gpio disable 2 Router hangs. Light up "NETWORK" LED
gpio enable 3 "Power" LED OFF
gpio disable 3 "Power" LED ON
gpio enable 5 "WAN" LED ON (RED)
gpio disable 5 "WAN" LED OFF
gpio enable 16 "USB 2.0" LED OFF
gpio disable 16 "USB 2.0" LED ON
gpio enable 17 "USB 3.0" LED OFF
gpio disable 17 "USB 3.0" LED ON
gpio disable 19 Router hangs.
gpio disable 21 "NETWORK" LED ON
gpio enable 40 "WAN" LED OFF
gpio disable 40 "WAN" LED OFF

Also, GPIO like 140, 55 and other similar combinations have impaction on the “WAN” LED (RED). I don’t understand how it works.

The main aim to set “WAN” LED (GREEN) when Internet access is available and “WAN” LED (RED) when Internet access is unavailable. Now, by default “WAN” LED (RED) when link to ISP is up.
