Experia Box v10a shows red light after unplugging

Hey, 

The household I am living in is using the Experia Box v10a, I unplugged the box to connect it to a longer cable. This however did not seem to work as it kept on showing a red light. Even resetting had no affect. So I plugged the Box back into the original cable which now shows the same issues with a red light. Initially on a difference place that indicates a WiFi sign a blue light is blinking, this eventually turns off, but the main light continues to be red. Also after resetting or unplugging. What a can I do? Basically nothing has changed but the box has stopped working.
