Use lan cable, pay wiring guy to do proper wiring to your room, that's will solve the problem

Mesh router/extender is bullshit la

Its not magic, its basically a wifi extender only. Without a solid backbone (aka ethernet/lan cable), the speed will be halved due to laws of physics. Now even have routers advertise using the 6ghz band for the backbone to solve this issue but 6ghz band is even worse at penetrating walls, so it's another bullshit gimmick.

You need a single high powered router smack in the middle, either tp link top router or Asus top router which will cost you few k, if u wish for 80% speed meaning 400mbps

Are you using one of the router you mentioned? Which model is that? Care to share 🐝🐝🐝

i just DIY and wire it in. of course neither this nor wiring guy will solve "ugly" or "dust" issue

If using android, I suggest this app for checking wifi signal:
https://play.google.com/store/apps/details?...em.wifianalyzer

No ads, easy to use, it also show details about other wifi signal in the area. You can then adjust wifi settings on your router to avoid congested channels.

Along the years, I have accumulated routers from internet subscription. What I do is just connect a lan cable from main router, then plug into the wan port in another router near my room. So I will connect to my room router wifi instead. I don't even need to spend a dime, except buying lan cable 20M cat8. I can't figure out why people want to waste money on mesh.

For your case, If u going my way, I believe u can route the lan cable behind your tv cabinet from the floor, then up to your balcony curtain hiding the wires behind the rail, then come back down on the floor edge and go to master room.
Or u can go further over the door edge to your bedroom 2.

If u have false ceiling that has opening, easier to hide the cable

Hi I need advise on my home Wifi network coverage in 1000sqft condo

Problem : In living room using 5Ghz network  I can get full speed 500mbps, but when I moved to Bedroom 2 or Master room I can only get <10% of the speed even with full Wifi signal with help from Mesh extender RE305 connected via WPS. Even with 2.4Ghz netowork I observed more than 50% drop in speed when I use it at bedroom 2 or master bedroom.

Current machine : Unifi provided D-link AX3000 @ Living room TV area marked in red
Extender : TP-link RE305 plugged at Bedroom 2 marked in red

I tried seek opinion from TP-link official store in Lazada, they suggested to me to get TP-Link Deco X20 or X50 2 units, 1 put next to main modem and another replacing the position in my bedroom 2, but before I actually invest in to this which may cost me about RM600+ anyone can give some opinion about this setup? I don't want to end up spent half k with no convincing result, I'm aiming at 80% speed at those dead zone if that is realistic.

i use a tplink ax73 /500mbps line    place in  house center / near stairs of my double storey  24x70 
and getting about  300mbps  and higher  on wifi  .
There are 4 antennas  for  AX/AC  band .  so  2 focus on 1 st floor , 2 focus on ground .

i am sure the Asus AX6000  or RT-AX86U Pro  can do the job too.  but cost is bit  higher .

Currently im using standard tm unifi router, not sure what model or brand but lately thinking to get a good router but my max budget not more than rm1.5k, at the same time didnt know which one is the best and powerful since im not expert in this matter 🐝🐝🐝

whats your house configuration .
2 storey ? 
or Apartment or ? 
floor plan

Router placement in critical.
what speed ur fiber ?

2 storey average size bungalow house, 500mbps, all bed room on the 2nd floor, usually all family members will be using or surfing net at 2nd floor which the router located, only sometimes on the 1st floor

Router on 2nd floor, centre facing all room

As  u did not mention any speed issues , or  weak signal/low speed  location.
i assume u ok.

i guess u  getting  about  300 mbps  in rooms on second floor
and about 200 on the ground floor .
use your best fastest phone to test . 

if above is about true speed  figures then go for the Asus  Asus AX6000  or RT-AX86U Pro
you may get  about 50 to 100 mbps on top of old router

you can consider using celcomdigi 1Gbps to get free FTTR. TIME also offers it if not wrong.

fibre to the room, they'll use super thin fibre line and you get basically full speed entire house.

best position for 1 strong wifi router to cover whole house
