@holleyberry: I’m pretty sure it’s gone for good (the modem is dead, as you can see. No little green power light). Might have something to do with how it was installed (its hanging out of the wall and is only kept up by two cookie boxes), its age (it’s over 10 years old) or the fact that it is covered in dust (maybe it short-circuited?).

I will answer the other replies I got over the past few days the day after tomorrow when I’m at our vacation home in England. A queue is up and running and will supply you all with pictures for another week.
