Hub not getting active, stays offline


Im a dutch guy with a UK ST Hub. So I have no idea where to get some support. But after having some ISP problem, my hub wil not get online. The 3 leds on the front give a solid white light. On my switch no ethernet light from the ST Hub also no ethernet light activity on the ST Hub. If I remove the batteries in the Hub put power on a ver faint white light starts blinking. Put batteries in 10 sec blinking white light and then solid.

I pust the reset button, no effect. 10 min no power, no effect. So who can help me? How has a idea?
