So a access point won’t work. A new router won’t work. I wonder what will work.
w5jck offered very good advice in post #6. I'll just add a few things to it...
As shared in your other threads, ONE ethernet run from the existing router to the space you are renting will then open the door for you to have your own access point, router, etc. That should cost less than co-buying a new wifi6 router (and avoid that tech potentially being held hostage when you are ready to move on), even if you have to have a professional come in to find a way to get one ethernet run through a wall from landlords space to your space. From landlords perspective, this will add value to the rental space since the future tenants can use the direct connection too.
If the landlord's router is next to a
hollow wall, this is not a complicated process: tie a heavy something (fishing sinker, washer?) on a piece of cord, punch a small hole (no bigger than a quarter should be enough) in the hollow wall directly above the router location and a second hole next to the router, fish the sinker-weighted line down the hollow wall until the person downstairs can get hold of it and pull it through. You may have to do a little jiggling/swinging to help the other end get hold of it. Then, disconnect the sinker and attach ethernet cable to pull up (or down if you prefer) hole to hole. Patch up the hole around the ethernet cable. When it dries, touch up with matching paint. Boom: direct ethernet from landlord to renter with more bandwidth than you are likely to be able to use yourself. Given speed test speeds you've posted in other threads, that signal won't be affected when landlord is streaming video... unlike shared wifi.
If you want to do it a bit more professionally, use an ethernet plate at each hole. If you need to use a professional to do this for you, hire one who can find the (hollow) path, run the ethernet cable, install the plates at both ends, and connect and test the ethernet connections through both plates. Then it's just a patch (ethernet) cable on your end from plate to either AppleTV or extender, router, etc.
If it happens to be near your AppleTV, plug the ethernet into AppleTV and use existing wifi for Mac, etc. If it is not near the AppleTV, plug it into your own extender/router and create your own wifi network just for you (where you will have 100% of the bandwidth on your wifi channel).
If there are other things near the AppleTV that also have ethernet jacks (currently leaning on wifi), get an extender/router/switch with multiple jacks (out) so you can then directly connect AppleTV with ethernet, anything else in the area that can attach with ethernet and set up your own wifi network too. Every other thing that can direct connect with ethernet is one less thing in your space taking a bite out of your wifi bandwidth.
And again, I agree with w5jck that the most likely issue is the location of your AppleTV relative to landlords router, given that you perceive much better signal with other wifi devices. Perhaps try moving some things around to get the AppleTV in a different location? For instance, if AppleTV is on the South wall, what if you moved it to the West or East wall? Rotating a little furniture can be a very cheap solution to your problem if the wifi signal is good- just not good in one general spot. If you want to test this before moving any furniture, get yourself a LONG HDMI cable or use a small HDMI-capable TV and move AppleTV around to potential new spots and test connections. Once you find a better spot, work out furniture/AV equip rotations to make that spot work.
ONE MORE OPTION (probably mentioned to you in the other threads about this): those powerline ethernet connections can work pretty well.
For a relative with solid walls but needing ethernet instead of wifi for- coincidentally- stable AppleTV watching, an experiment with those yielded a fast enough connection with no wall holes/drilling. It's easy enough to try those first. Basically that would be:
- Landlord router ethernet jack: ethernet cable to one powerline ethernet box plugged into the wall.
- Sister powerline ethernet box plugged in in your space: ethernet cable out of it and into either AppleTV or your own extender or router... but you could test ethernet speed with your laptop.
If you try this and get it working, the next thing to try is moving your end of the connection to a plug perhaps close to your AppleTV and seeing if it works there too (with these things, some plugs can work and others won't). If so, that can deliver a wired ethernet connection to your AppleTV and your Mac, etc can continue to lean on the wifi that seems "good enough" (to you) on those other devices. I just took a peek at Amazon and none of those on the first page are more expensive than $120 with many with good ratings down below $50.
I would generally NOT expect that to work better than a direct ethernet connection and it may not work at all depending on how that place is wired... but that will be easy to try, perhaps BEFORE you drill holes and/or partner on a new router. AppleTV doesn't need super fast connections even to stream 4K video but it does need a relatively steady connection. So this might be a way to get "fast enough" WIRED without much expense or a true cable run.
