}I'd like to chime in on your point 2). (thankyou). I also loose the link

}blasted thing with a timer - crude but could be very effective.

Well... as a starter hack:

 while true; do
    traceroute IP_OF_PROVIDER_GATEWAY 2>&1 | grep "^ 2" >/dev/null
    result="$?"
    if test "$result" -ne 0; then
        if test "$state" = "up"; then
            echo DSL appears to be down at `date`
            state=down
        fi
    elif test "$result" -eq 0; then
        if test "$state" = "down"; then
            echo DSL appears to be back up at `date`
            state=up
        fi
    fi
    sleep 60
 done
