Internet and TV going out

My internet and TV lose signal always at the same time, and about 3-5 times a day. Each time it happens they are only down about two minutes, but its pretty annoying. A tech has already come out and couldnt find any major issues, he said the line quality seems decent.

I dont understand why its going down, because my internet latency is always very good and the TV image quality is always good. There is no indication that there is a problem until everything comes to a complete stop.
