Welp Mikhailmark - you missed pretty much everything about my post. FWIW - I’m personally skeptical a LPS on a modem or router will make a difference, but I guess I need to repeat/clarify a few things.
1) Nobody is suggesting a change in the data quality, quantity or timing.
2) So Ethernet transmission is designed for nuclear war. Let us all hope that robustness is never needed. Not relevant to the discussion. See point 1.
3) How well you understand network protocols is actually interfering with your ability to think critically and ask “what don’t I know?”
4) I’m skeptical, but don’t have experience so I don’t know. You don’t have experience yet are speaking in absolutes.
5) I’m not saying you’re wrong. I’m saying you don’t know. What you’re asserting as fact is actually just speculation.
Chill.
Maybe try it out of exasperation and tell us what you found out. I’ll happily accept you heard no difference and why you think you didn’t hear a difference if that’s your experience.
