Ethernet Switch- what's the point?

@nonoise you are misrepresenting what happened. You made a bunch of claims and linked to a guy building his own RF detection device and claimed this guy was a genius and knows everything about RF. I pointed out to you that EMI/RF devices cost $20 on Amazon, and this guy didn’t know anything more than average Joe. 
then you went on to post a bunch of links that contradicted your claims, a while stating that they support your claims, and finally you admitted you actually have no knowledge of the subject at hand. For which I give you kudos, no one else has admitted in the face of facts that they actually don’t know anything.

but you are correct in that I have tried a few Ethernet cables, I still have one in my box of cables, and I have tired the etherregen. I also said why I tried, which was there is no way these should work, what am I missing? 

@recklesskelly  people are literally saying to spend thousands of dollars in the thread…

thanks for your comment on my grammar, it matters a lot. 

@fredrik222 I have seen a range of $1349.00 (recommendation on LHY SW10) and $89.00 on an isolator switch. You should change your moniker to Chicken Little. Again why should you care if I spend $20K on a switch? It is our money not yours.

I think you’re confusing me with someone else as I don’t recall stating that. What I did talk about was how TV signals show that it’s not such a clean and sure thing and you shot me down by saying it was a different medium so it didn’t apply.

I also linked to someone who spoke of the issue that nothing really performs at the levels intended at a consistent rate and that IT companies intentionally throttle down to compensate for traffic resulting in less than perfect transmission, which you also dismissed.

All the best,
Nonoise

Question is very simple. If you are using a very unefficient protocol like https, which relies on heavy buffering, all is reduced to the quality of client (the webplayer most likely). So, which switch/router/cable to use is no sense question.

If you are changing router/switch/cable and you hear big differences, logic says you are using a UDP like protocol, or the https client is extremely poor.

My 2 eurocents.
