I have a TP LINK RE200 Range Extender. 

it used to work fine but recently it's just stopped working. 

the LED light will keep on blinking, then all the lights turn green for half a second, then the Wi-Fi led turns red and then the power led is solid for 5 seconds before it starts blinking again and the whole sequence keeps restarting. 

I have moved to a different power points, even right next to my router. 

I have pressed and held the reset button for 5/10/15/20/25/30 seconds multiple times but the power led just does not turn solid. 

I've used the extender for few months but this issue came up a week ago and isn't going.
