My PTCL 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:
These values drop significantly 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. I will appreciate any help you can offer.
