GL.INET AR-300M I2C

Hello to all Im new here.

Documentation says that some early device of AR300m wont work with I2C .
" Note: I2C is not working in some early version of the router."

Ive already tested the default I2C pin which is GPIO 17 and 16 .But i cant detect any address with
i2cdetect command.

Can someone till me if my hardware version works with I2C ?
Im using AR300m with hardware version GL-AR300m-V1.5.2 .

Regards ,
Dave
