my R9000 is covering good its floor but downstairs signal is too weak (2 walls, 2 doors and a stair in between). I have already tied some LAN cables connecting floors for wired network outlets, so I was thinking to place an AP using a LAN cable together with a POE injector to get both network and power from upper floor (where DD-WRT router is placed). I'd like to have a "seamless" wifi connection as if I was connected directly to the main router: same SSID, same password, same behaviour, like on a mesh (please correct me in case of mistake).
I was thinking at UniFi APs freesbies (Lite, LR, Pro): maybe they are good for the job?
I would accept any suggestion, even about configuration....

|Is it safe to assume you're using Italy as your regulatory domain on your wifi settings?
If so, Italy only allows weak dBm:
|country IT: DFS-ETSI
(2402 - 2482 @ 40), (20)
(5170 - 5250 @ 80), (20), AUTO-BW, wmmrule=ETSI

# 60g band

# channels 1-6 EIRP=40dBm(43dBm peak)
(57240 - 71000 @ 2160), (40)
every 3dBm is 50% power +/-.
Both radio domains have to be the same, or the router won't broadcast.
choose your 5ghz channel wisely. see my signature for some useful links on this topic.
