Frequent disconnection every 15 or 30 mint

Its been just a week since I'm using my dsl connection over new fiber optic line, My conection is

1 mbps, things were going pretty smooth but since yesterday I have having frequent disconnection like after every 15 or 30 mints it goes away for 5 mints

below are the the stats can anyone look into it if anything wrong with these stats

Your stats look great, u shouldn't be havin any disconnection problems but just incase place a complain on 1218 or call ur exchange and have them take a look at it
