Possible advice on bad DSL signal

Hello, I have century link dsl, which occasionally I face DSL connection issues, the tech that came to my house last week thinks it was interference from another jack in the house, and disabled it. But the signal keeps dropping, sometimes for a few secs, others for several hours, I have done many factory resets to my modem, as well as cleaned the wiring in the junction box outside my house. Here is the system log for part of my down time today,
