Increase range on multi level dwelling question

[GGG]

Need some product advice on a top end AP for my house please.

I have triple story home, with open entertainment decks on each level.
There is no way to run cables to various AP on each level, so I was hoping to use an outdoor LR/HP AP that will improve my range and coverage.
I have a TP-link TD W8970 modem sited on the first floor.
This gives good coverage on the first floor, but I only have coverage immediately above the room where the modem is sited on the ground and second floor.
If anyone has some product ideas it would assist

Powerline adapter ? You get ones with WIFI that have their own AP, have not tested so cannot say.

Have a look at the Ubiquity range.

Thanks, I have three Ubiquiti LR AP's inside one of my houses, do they also make an outdoor?
My house is at the coast.
