u need to describe "the house"...

how many storeys... how long, low wide...
where will router be placed.
what devices... how many... posiiton... ethernet or wifi...
what speed u use now...

there is no one big universal power router to serve all houses, all purposes...
give details, poepl can comment, suggest.

your problem is a typical "i hv bad wifi in my house".
countless threads, countless users struggle with it, with no obvious WIFI solutions.
factors are yr internet speed, distance, barriers, router, and device n application use.

fortunately, i have a lesser problem of such albeit similar.
.. your house is wide but not tall... i dun think it is worse than mine in terms of wifi reach.
.. 50mbps is fine but will help if u can upgrade to 100mbps.
.. becos of losses, base 100mbps can still give u decent net speed at the furthest corner.
.. better router will help, so will the pc wifi adaptor.
.. front lower right (left) to back upper left (right) will be the most challenging.
.. theoretically, the "balloon" coverage can be reshaped by tilting the antennae backwards to reach higher, but... i find it rather useless.

i am using asus rtac1300uhp; pc with asus usb-ac55 adaptor; 100mbps.
couldn't get good results with original 2.4ghz pc, but the 5ghz adaptor changes everything

router front lower left, pc back lower left, 55ft, 2 walls, wifi... this test is with 2 other devices doing heavy stuff:


with router at front lower level, all devices at same level are fine, great speed.
upper level, 5ghz devices can get 70-80% of the speed, except for the worst blind spots - these, u must avoid... move yr pc, table, bed, etc.
2.4ghz devices will get about 50% of the speed, which is good enough for most purposes.

i do not know if a router double or triple the price will do a much better wifi job or it will be a point of diminishing returns.

my router been on for 2.5 months... 24/7, latest firmware, no reboot.

2.4ghz has farther reach but losses are severe too.
for yr distance, 5ghz will get u more than 2.4.
but further than that, it will go to zero very quickly.

i dunno ac1200, but i suggest u do not save small money if buying new.
better spend a bit more so that u are covered now, as well as when u go 100mbps.

the longer u keep this issue open, the more confusion and "bright ideas" u will get.

i am glad i did not get exotic, do just something v simple.

really, my experience, just one good router, forget all the rest, yr house wifi will be fine.

it's not like it is a 3 storey 80x150ft footprint bungalow with 15 rooms.

all the best.

your main problem is wifi lower corner to upper other corner.
these 2 areas in any house are most unlikely to share the same phase of a 3 phase power supply.
hence homeplug will do nothing.

other options will involve laying cables, or repeater, extender, access point - more equipment, work, more money, more headaches.

your house is similar to mine, quite typical actually.
no need to fret, wifi tech with good new routers are good enough for that.
higher priced routers can do the job but rtac1300uhp is good enough.
and very consistent: 55ft 5ghz


if u buy at shop, might as well take your unifi id/pw with u, get it set up there with latest firmware, go home plug n play, easy.
remember if yr pc does not have 5ghz, best tobuy a dual band adaptor as the same time.
then u see the improvement in total.

if u get into difficulties, can post in asus thread, many asus users can help u, if u need.
my experience is in post #6739.
