installed the deco m5 succesfully on first try then went out of country for a while but when i came back the m5 is now blinking red with no wifi. i already tried unplugging and plugging it but it still blinks red after a steady yellow. i also tried resetting it from the back but it keeps on blinking yellow for hours already. is it supposed to blink yellow for longer than that? or am i doing something wrong. please help
