My broadband went down at 1pm today and hasn't came back on yet. The TV has been working fine but has now started to display the connection problem pop up which won't go away, meaning not only do we not have any Internet but we can't watch TV either now. I've tried rebooting the hub (hub 4) and the 360 box and nothing is taking this message away. Does anyone have any workaround or suggestions? Tearing my hair out here.
