Wi-Fi range extenders: any recommendations?

Here’s the situation I'm facing. I want to share my internet connection with some neighbors living in the apartment directly above me, but my Wi-Fi signal just isn't reaching them. I'm trying to figure out what the best hardware would be to boost the signal, and whether I should set it up in my own place or if it would make more sense to put it in theirs.

You know those guys who basically plug themselves into wall outlets? Or maybe something more like this ....if there's an antenna port on their PC's Wi-Fi card

I don't want to start a whole new thread, but I’m dealing with a massive networking headache. My router sits on the ground floor (running on 2.4 GHz), but my office is up in the attic, and there is just no way I'm tearing apart the walls to run Ethernet cables through the whole house. Right now, I’ve tried using Powerline adapters to send the signal through the electrical wiring. It works, technically, but it’s garbage. I’m getting huge packet loss whenever I try to stream anything through GeForce Now, and even switching over to standard Wi-Fi isn't much better. If I plug directly into the router with a cable, everything is flawless, but obviously, I can't do that from upstairs.

So, what am I looking at here? I need to get some kind of 5 GHz setup going—which is what everyone recommends—maybe paired with a signal booster, an extender, or whatever else actually works. Does anyone have any solid suggestions on what I should actually buy?

Also, can I actually recommend a specific router to use with fiber internet, or am I stuck using whatever junk the ISP provides?

It’s not actually your Wi-Fi speed holding you back; the real killer is just trying to push a signal through all those walls. Honestly, switching to 5GHz might even make things worse since that frequency struggles way more with physical obstacles.
You could try slapping an extender somewhere halfway between your router and your room, but just a heads-up: you're basically cutting your max speed in half and you'll probably deal with much higher ping.
Those Powerline adapters you have should work okay if you give them a shot... just try plugging them into different outlets in the room. Ideally, you want them on the same circuit (like the same phase), and definitely stay away from any outlet that's already powering your PC or gaming rig—that stuff usually messes with the Powerline signal.
If tweaking the channels doesn't work and you can't drill holes to run a LAN cable (or any wire with at least four strands), maybe see if there's a way to fish it through old phone lines, coaxial TV conduits, or even an unused chimney.

I think I might actually give what you're suggesting a shot. I’ll check out some other influencers too, and honestly, I hadn't even considered that whole chimney thing—that could actually be a killer option.

Does anyone know if I can actually pick up an adapter like eth > coaxial > eth around here? I looked online and found those MoCA adapters, but I can't find anything available locally in the States. I'm currently running a powerline adapter that uses AV, so maybe switching to AV2 would be a better move? I guess maybe that's where I'm hitting a wall—I just can't seem to get the speeds I'm actually looking for.

sry, but that was a total rookie mistake on my part. I had the router and its power adapter plugged into the same outlet strip that had a built-in USB port—which was actually powering the router. Once I finally separated them, boom. Everything's working fine now.
