Assalam O Alikum,
Recently i had problem which i was unable to solve .... now i finally connected my phone line (Black copper wire) into the ethernet wire and from there i split telephone and modem through splitter.. I am still receiving the same snr which i was receiving while my concealed line was connected. 8.0/8.0 it sometimes gets 9.0/34.0 that happened in concealed line too . I am still confused what could be the problem.
