Check tplink be600 or asus RT-BE92U There are many, check amazon
Yeah it works great, i have tested both. Only issue woth asus is they dont have a tri band extender like RE653BE from tplink.
Yeah honestly that would work just fine. Im a big propieter of MESH only because where i lived I wanted to be hardwired to the devices (pc and console) in my room and I was able to do that by having a wifi Node in my room on top of the base node (router) in the living room. That and years ago they had way better customizable options and UI on their fancy apps. For what you are trying to accomplish I think you'd be fine with the tp-link but double check you can actually just plop it in the middle of the house based off your fiber run! I use EERO, I love it, have had the same mesh for like 7 years and still running great.
Bro this sounds like a basic residential setup, if OP needed a more sophisticated setup he would have a made more "technical" post in asking. You want to recommend this guy dropping cables when he just wants his phones and tv's connected more than likely. If he owned equipment that needed more, im sure he would be aware of their requirements. You are being **hella** extra even stating "Mesh is a solution when you absolutely can't wire" 90% of homes use wifi. Mesh is a great wifi solution. **OP literally asked for suggestions** so I give a example solution that worked for me and that was and has been amazing. All of a sudden I have no technical background based off god knows what assumptions you are making, you literally offered zero context in any of your replies. You clearly have no people skills.
TP-Link BE9700 has been good for me.
Really? Mine has been running flawlessly thank goodness. Speeds and range are perfect for my house. Whole house is connected and do not have any drops or slow spot in the house at all. Hope it stays that way, I lose my mind on slow wifi
Your plan is solid, that router more than capable to handle the load you stated. Are you going to drop the fiber or ethernet cable from the ceiling in the middle of the house? My concern is if not , and running the line on the floor, someone who drag their feet sooner or later will trip and pull all the equipment onto the ground & break.
Sent the BE9700 back after 7 days of random drop outs both wired and wireslessy.
