I'll be the counter comment. I absolutely despise my 3x Deco x55s. They are absolutely garbage and are a joke of a product.
At first I loved them, but then I started having what I believe are DHCP problems and memory leaks. I can't confirm this because they obfuscate everything through their app with hardly any administrative abilities. Basically I have devices that will just randomly drop and can't reconnect because they can't get an IP address. (I have maybe 50 devices...)
Oh, and if you don't have Internet your wifi basically craps out because it's all cloud based.
I can't custom configure different WiFi's in a way that is useful for my house, and can't really configure different vlans.
But worst of all there is simply no ability to troubleshoot when things are broken.
I'd love to put openwrt on them, but haven't been successful so far.
I really hate my Decos and I wish I never bought them
I've used the S4 AC1900 trio (older but worked well), along with the X55 trio. Still Wifi 6 but decent coverage.
The one failure was the Eero Mesh 6, stopped working but got a replacement set from Amazon and shipped the old set back. No problems since then.
If they can’t get a cable, have them do a mesh device. Turn the WiFi off on the router, and add a 2 or 3 mesh system like eero. I use TP-Link Deco myself. You hardware 1 to the router and put the other 1 or 2 strategically where you have power only.
Eero is going to be a bit spendy in comparison to TP Link.
[This TP Link is around $160](https://a.co/d/8VPQ1au)
I have the AC1900 Deco which is more around $120 but not as good. I bought that a couple years ago.
From a cost/quality/ease of setup TP Link Deco’s are definitely in the running. I have 3 in a 2600 sq/ft 1 floor house with no problems. Granted mine are all hardwired in AP mode but I imagine they would still work well in mesh.
With the limited info you provide, I would suggest going for two X55, located as you describe.
If you go for four, it is probably best to install the third and four in the middle of the floor, not at the far end.
