New BE6500, when gaming and someone uploads anything at all. My ping spikes and i get constant packetloss which is incredibly annoying.

I have 1000/100 fibre, all connected via ethernet.

I have tried limit the upload to every number possible, it doesn't help, infact qos makes my bufferbloat worse.

The thing is they aren't even using all of my 100mpbs upload, just like 1-10mpbs.

I even changed ISP to see if that would help, didnt..

 Please someone save me from this packetloss suffering
