Hi there. When I bought this 2 years ago, only first few months, it worked good. But as it kept lost connection, I stopped using it.

Now I want to use it again. However the whole LED light kept blinking and I can't go next step. Only power light is stable though. 

I use same router/password from 2 years ago. I pressed reset botton on extender too. 

What can I do to reconnect? Pls help me. Thank you
