this is related to my other thread about opnsense/pfsense (
https://forum.kitz.co.uk/index.php/topic,27390.0.html)
i recently moved from a fairly new build 2 storey house (all internal walls plaster board/wooden stud walls) where my existing router (ASUS RT-AX88U) covered all area of the house very well (both floors), so a 1930's bottom floor flat where all the internal walls are thick brick and my WIFI is now barely leaving the room where the ASUS router is.
my temp solution is that I've installed a TP-link powerline adaptor to add WIFI coverage in the furthest away part of the flat (which actually is probably only about 40 feet max).
this is not what i want the permanent solution to be though.
so I've decided to go away from the "all-in-one" solution of the Asus RT-AX88U (which is actually a very good router but can't handle thick brick walls), to a separate device solution (hence the opnsense thread).
so my question is about WIFI APs.
if money was no object i'd go full Unifi (dream machine pro router, Unifi APs, Unifi switch etc), but money is an object.
so I'm looking for recommendations/suggests about APs that i can put in place to give me back the proper WIFI coverage. I'm probably going to need at least 2. and ideally they are PoE powered so i only have to worry about getting an ethernet cable to them. i can mount them either on ceiling or high up on the walls (i will need to drill holes for the ethernet).
they have to be at least AC WIFI 5, my laptop has AX WIFI 6 but in reality it never uses.
see attached floorplan.
the virgin modem and ASUS router are currently in the office (marked in red).
the tplink WIFI extender is in bedroom 1 (marked in red). if the wasn't there the WIFI coverage in that room would be virtually zero.
in the living room my Nvidia shield has no WIFI connectivity (although i haven't tested it yet with a full 4K HDR BRRIP, which it didn't have a problem with in the old house), but my iPhone will keep losing and reconnecting to the WIFI in that room.
all the walls are brick, with the wall between the living room and bedroom thicker as it used to be a chimney stack.
