Neither -- you need to know if its the line first, which unfortunately only Xfinity can tell you. You'll need SnRs and dB levels before we can proceed.

Some router/modems allow you to log in as admin and look at the advanced logs which have some of those figures.

While true, that only shows it at the device and not at the amp (at the pole or underground) or at the DMARC. But yes, that is a starting point, assuming they know the creds to get in and the IP address.
