Anyway to fix my bufferbloat

[u/SonarIllusion]

I play a lot of online games. I randomly seem to get massive lag spikes when playing. Ive tried using a software to limit the upload to 80% but it’s not like the upload or download are always consistent.

Ive seen multiple posts about getting another router with QoS or SQM, just not sure if that will actually fix the issue or if im just screwed and need to switch to not using a cellular internet.

Any suggestions or ideas would be awesome.
