My internet has dropped out entirely since last night. After ringing Snap I've changed the modem's location and DSL cable, and did a factory reset but still no luck. This same issue has been happening on and off for the last week but this is the first time it's taken more than an hour to fix itself after rebooting.

The modem log shows this. After this the ppp1 stuff loops with the odd ACK/REQUEST messages thrown in

Is it the modem that's buggered? The line?
