I live in an area that has long had really bad internet but..........we now have fiber and all that brings with it.
We have 100 but can get 1 Gig if we want and it would help. The problem is that in far away areas of our home it's nowhere like it is near the router. I've added several of those extenders you plug in and have to code to various devices. Looking online it looks like the Powerline extenders do more with much less effort. I'm talking about the ones that use your household wiring to carry the signal.
Most of the info about them is sales stuff so I thought someone here must have already done the research and have some real world experience.
I kind of know how they work. Do they really work as well as the ad's say, are the connections reliable, is there a brand to get or stay away from, etc.?

I used to use a pair of powerline adapters to get internet into a back bedroom that was just too far from my router. They seemed to work pretty well, though I never did any speed tests back there. I 'believe' the adapters are dependent on how well or poorly your home is wired. Do they work pretty well. Yes. Are there better more expensive options. Yes. It all depends on your budget and goals.

I've been using these for years, not a bad option.
There may be more packet loss/resends due to the fact that there is no real proper shielding... not interested enough to "Fluke" the home network.

But not of any consequence for general home use.
haven't run servers/applications at home in too many years to remember.

Although it may outpace your internet connection, faster is always better.

I'm partial to NetGear, though I am sure other brands could be just as good.

One thing to check on, I had some older NetGear units exhibit what I would think is excessive heat. Dumped them and bought the next generation.

Hope this helps.

How big in Sq ft is the house.

I would first tryout a mesh network first.

I have used and tested a bunch and settled on recommending TP-link.

They have two or three models and all work well.

They now have a power-line and WiFi combo unit that would also work for your application.

I tried powerline adapters when we lived in an apartment due to all the Wi-Fi congestion. It didn't work for us because the wiring was so old that there was too much signal loss.

If you have newer wiring and a clean-ish panel you should be OK. If you have older wiring and a lot of sub panels or rat nest like runs you may have issues.

I’d get a TP-Link mesh router and a repeater or two before I did powerline Ethernet.

I tried it years ago and it worked just OK but I can’t think the signal is going to be great or reliable having to travel over the same wire with AC current.
