Disconnections/Slower DSL speed

[classna]

My DSL phone line is directly connected from DP to my modem/router and every now and then my internet gets slower and i get frequent disconnections because my SNR Margin and other values drop. To get the values back to normal, i connect the phone cable to my landline and then call myself from my cell phone. I then reconnect the cable to my modem and restart it. This get the values back to normal and my internet connection stays stable for a few hours before i have to repeat the same action. My dsl stats when normal are:

Downstream / Upstream
SNR Margin : 26.1 / 9.4 db
Line Attenuation: 25.9 / 16.4 db
Data Rate: 9216 / 1090 kbps
Max Rate: 21088 / 1109 kbps
CRC: 0 / 0

These values go worse after sometime like my SNR Margin gets as low as 7 or 6 and data rate drops to 2000 downstream etc.
I have checked my phone/dsl cable and it doesn't have any joints and i don't use my landline phone so i connected the cable directly to my modem. I tried using splitter but that didn't fix this issue. I am guessing this might be static or some kind of interference around my cable that develops overtime and calling my landline fixes it. Please help.

You might want to call your DSL provider. Have them test there could be something wrong with their line.

I already called them so many times but their support is very poor and unfortunately thats the only DSL provider in my area. I hope someone here can help me diagnose this issue.

Well you can try plugging a computer straight to the modem and checking for any physical damage to the phone lines themselves. If you still have a problem then the issue is either on your DSL providers side (can't help you there) or your house phone lines (you can replace them) no real way to test them without the right equipment though.
