Help me understand better solutions for ethernet


I've been reading quite a bit lately here and elsewhere about ethernet cables picking up noise and how to mitigate that. The three main options I've come across seem to be:

1. An audio-grade switch box like Uptone's etherREGEN that uses their "moat" technology to clean/block noise.
Pros: fairly straightforward
Cons: extra gear in the chain

2. Converting the ethernet to optical to block the noise such as the direction Small Green Computer takes.
Pros: optical blocks the hash carried by ethernet
Cons: There's only one streamer/dac that I know of (Lumin X1) that allows for Optical in so again even more gear in the chain to convert to optical then convert back to feed ethernet to the steamer/dac.

3. Wifi - just go wireless and remove the ethernet cable completely (well mostly). 
Pros: Certainly the cheapest, easiest and tidy route
Cons:???

Very curious to hear from others your ACTUAL experiences (not your theories based off god know what...)

I had 75’ of Ethernet from the router to the stereo room which went to the bridge of my PS Audio Directstream Jr. I never thought anything of it and in fact I always assumed an Ethernet connection was better than WiFi. The DSJ has no WiFi capabilities. Like you, I started reading about noise in a hardwired Ethernet connection and decided to try a WiFi repeater that has an Ethernet port. So basically I program this WiFi repeater to connect to my existing WiFi then plug the Ethernet from the DSJ into the repeater. I was stunned at the difference between Ethernet and WiFi in my application. I’m definitely hearing deeper into the recordings, plus it was dirt cheap. I spent 50 bucks on a Linksys. You can get something like that from bestbuy and give it a shot and see if it helps in your application. If not, take it back. Best of luck.
Jond - You'd think the rural setting would be a huge plus, but living 3 miles from a top secret underground military facility who knows what's floating around out there. Stranger Things playing out in my backyard. LOL.

Thank you all for thanking the time to reply.

I think the best route is to order up versions of all three solutions and test/listen. Most come with 30 day trials so can't lose. 

Latitk - I will certainly add Eno to the list as I do like the passive route.

Arch2 - I have just received a TP Link access point that Upscale audio recommends but it's giving me fits trying to setup in client mode. I agree for $25 if it sucks I can use it elsewhere around the house. 
ENO works.

So does the Etherregen

I run fiber but never really listened for benefit-it helps me sleep at night not worrying,
 but I think I have the wrong SFP modules, so waiting for modules and cable from Sonore.  will test for benefit soon

Added a clock to the Etherregen and LPS- both helped, the clock more
also have SOtM cDBL CAT7w/filter-definitely better than standard ethernet cable

it's a very deep rabbit hole but worth exploring
Well it took a 1.5 hour visit from my internet provider/IT tech guy (he arrived on 20 mins notice at 8:30 pm on a Saturday night while snowing = amazing customer service!) to setup my TP Link access point. What should have been an easy 5 min install by me turned into anything but.
Tomorrow when I have some time off I'll A/B simple wired CAT 7 vs. wireless. I'm not sure there will be much difference only because my internet comes to me wireless via an ATT tower here on the mountain. Currently no one out here has a hard fiber line except the govt, who has five separate independent lines but their not sharing...  From there will continue deeper down the rabbit hole as you say.
