1. 2 storey house, approx 30x60 build up
2. Router will be placed in the front end of the house on ground floor, which is in the living room
3. Currently facing problem on my desktop, as wifi adapter is weak as well. My room is at the back end of the house on second floor. So basically is from 1 end to the other. I think the total number of devices will be around 10.
4. Using Unifi 50mbps
My room is on different floor. If thats the case what kind of antenna should I be looking for?
For point 4, yea someone in my house is torrenting chinese show most of the time but not as hardcore as you said
At first I thought of changing my adapter but then again might as well change the router so I wont the problem for other devices. I have tried wireless AP with a TP-Link AP before. But for me seems like not very stable as my device cant connect to the AP most of the time and will revert back to the original router but not sure if its my TP-Link AP problem or not.
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.
