Hello friends

I have a problem I can not solve

You can watch the videos I send to the echo.

WAN PPPOE client is a problem.

As the internet goes on the normal course, the speed suddenly goes down.

After 15-20 seconds it rises again in the chart.

By the way i am pinging example google.com.

Ping time out goes down when speed is zero

You can review the video in detail

Could the problem be my own local network?

what is your opinion ?
