Internet suddenly out

[#1]

Our internet has suddenly gone down. The wifi light is lit, the broadband light is flickering and the internet light is out.

Nothing has changed, as far as I know. It's been working for some years and just suddenly ceased. I tried unplugging the modem a few times. I checked the phone wire and it seems okay (the phone in the same socket is working).

What do I try next?
