Would to ask I currently have Asus rt ac68u. What would be my options to setup a mesh WiFi? I am on Unifi 500.

thanks.

So you mean that if i have network cable to 2nd floor from my 68u down stairs, just adding a wired access point at 2nd floor would work better? No compromise to the wifi speed right? Both can set the same SSID so i can go up and down and my mobile can seamlessly switch between them?

Guys i need some input. Is Asus AX86u worth to get? Of course it's crazy expensive, does it really justify the price vs performance you get?
I am currently using AC68U, but recently notice it sometimes will suddenly have wifi connection issues until i need to reboot it.
I am thinking to get another router to replace it as main router, then move this to second floor and use wire to backhaul extend the wireless network.

Yes i know but is it overkill to get ax86u? or something like ax68u is good enough price vs performance.
I am planning wired backhauled aimesh if i get another router.

Oh sorry, I should have mentioned it in my ori post.

My Unifi is 500mbps. My router AC68u is currently in living hall.
Basically now only me and my wife in the house, and we are working from home now so a lot online calls during the day, and she complained bad connection a lot lately (she is furthest away from router on second floor back room) while i am also working in second floor living room and occasionally also experience bad connection and reboot router helps restore it.

Other uses include streaming Netflix at night, downloading stuffs. I occasionally also pubg mobile on ipad while wife is streaming netflix on TV.

I generally feels the router performance has degraded a bit but not sure whether internet also a factor. 5Ghz ssid sometimes also disappear, even when i am near to router.

Thanks for your reply, i will think about it. Maybe just 1 shot hentam 86u

Btw, if i use AX router as main router, then move my AC68u upstairs and setup wired aimesh, it can work right? Not too familiar with mesh network, but i suppose with an old AC node, it won't force the AX to downgrade to AC to maintain compatibility right?

Does it work like this, so if my wifi 6 client connect to AX router then connection is AX, and when it connects to AC node, then connection drop down to AC?
