I've just got a new ZYXEL NR510E Router from the Three shop & I've found that the DC connection is a different size to a previous ZTE router. That DC connector size was 5.5mm x 2.1mm. I have done some searching before coming on here to find out the size of the DC connector on this new router but I can't find anything. I would say that it is 5.5mm but the other size I don't know what it is. So, could anybody confirm the size/dimensions please?
