I had my internet appointment yesterday and still no internet

I had my internet setup yesterday and chose to do the Manual setup followed the steps on the sheet, but I can't get passed the 3rd step. My modem/router only has the power light ON and nothing else lights up, I tried the reset behind for 10 seconds and that didn't help either. Left it plugged all night for maybe an update and woke up this morning onyl to see the power light still ON by its own.
