Dont have that much money and time to hack all my walls and do this now
Most of the times I would be doing my work & spending my times at the living room & got a TV box. But, would be ideal if i just could cover other bedrooms with WiFi signals since other family members spend their most their time in there.
I do agree on the health reasons too.
You don't need much money to run direct ethernet cables concealed in cable covers along the walls just like your electrical cables.
Since you mentioned that connectivity in bedrooms are just for convenience, you don't need wiring to cover all rooms then. Stick with your original plan of relocating the router opposite the dining table as you've marked. Run just a single ethernet wire under cable covers along the wall further down the walkway leading to the bedrooms to somewhere right in the middle of all 4 rooms.Make sure you have a electrical socket nearby for convenience. Place just an AP there either wall mounted or on a small rack. Turn it on/off only when you need to access internet from your room on demand. That should be good enough to cover all 4 rooms.
The AP/mesh unit works just like a wired switch except its connects to your devices wirelessly. All routing functions will still be handled by the main router which you plan to place at the hall.
For your tv box, you might also want to run a cable across the wall to provide a port for your tv rack.
You probably need 2X 10M of CAT6E cables for both the bedroom area AP and TV box. That should leave you with 2 more spare ports on your router for other purposes maybe a closeby workstation PC.
Under RM300 should be more than enough if you can get reliable contractor or friend or DIY.
