Hello i am needing some help with my new internet connection. I have comcast and am wired directly via ethernet. My speedtests are getting 130Mbps-180Mbps with about 20-50 MS. however when i open up task manager and check ethernet i notice that there are times the send and or receive will drop to 0 and then can shoot up. My pages will load and it never shows i actually drop internet. however any online games i play the MS will spike to over 4k for a few seconds then drop right down, or sometimes it will kick me. So my question is should the send and recieve actively ever reach 0 or should it always be at something? I have tried Google DNS on my desktop and also reset the modem and tried different ethernet cables. please help with any ideas. Also when i run a ping test i dont have any packet loss

It greatly depends on the application. If you were to watch youtube 4k videos you will see it send huge blocks of data and then send nothing and then send huge blocks of data. Even file transfers tend to work this way, it is part of what is called TCP windows size.

Games are or maybe live stream video are a little different. They send data a fixed rates constantly even though they too burst the data the bursts are just much smaller.

This problem could be buffer bloat in the ISP network. Since you are not doing transfers it is unlikely it is your machine causing the bloat. This means it is your data combined with your neighbors. Some router have QoS settings that will fix the buffer bloat but only when it is caused by...

Some router have QoS settings that will fix the buffer bloat but only when it is caused by something in your house. There is no way to fix the ISP. A good indication it is a ISP issue is if it does this more during prime usage hours. Try very early in the morning and see if the problem happens.
