Looks like a lost connection between hop 2 and hop 3. I'm not an expert on modem "retrains", but that looks a lot like what's happening here. You're completely losing connectivity between 2 and 3 for about 10 seconds at a time - and then it repeats itself a few times.

This should be "catchable" by your provider - maybe send them a copy of the attached images, and see if they can look at their logs during the periods here (1:53.30am).

You lost connectivity in Netflix. You capture a picture of the problem directly that shows the loss at hop 3, but not hop 2 - and also at the final destination. This is "textbook" - either a bad modem (obviously not, or 3 wouldn't be bad), bad wiring (or wiring related problems), or bad equipment/configuration at hop 3. You don't have a lot of tools to find the problem in more detail, and your provider should be able to help. The problem lies somewhere between the DSL modem and the device inside your provider's complex at hop 3. Lots of territory there, but your provider should also have some decent tools to narrow it down further.

Good luck. Let us know what you find here.
