Frequent Disconnection

hello everyone i am using 1 mb ptcl broadband.few days ago i started facing a problem my router restarted every 5 mins and its happening daily now can anyone tell the solution pls

here are my line stats:

is there any distortion in your line?

Your SNR Margin is on the borderline, this could be the issue. Check your phone line for noise. There should be no patches between the phone box at home and PTCL DP outside.

there is no telephone so i cant check any distortion i have registered a complaint by calling at 1218 hope they fix it soon :/
