Hello there, I have a Wn802Tv2, and purchased a USB to TTL cable using pinouts that another user had success with. 

Thing is, Putty opens but will not let me type anything in the terminal window, and I cannot ping the device.

I have used the config suggested, checked COM port numbers etc but there seems to be something preventing it fully communicating. 

Would you be able to help me in any way or suggest something to try/check please? 

All I am getting is a flashing green cursor.

I work with these things and I would love to be able to do this as it would save me so much money and stress! 

Many thanks, David
