buy another gigabit router.
pull a physical LAN cable from main router to the 2nd router downstairs.

buy multiple wireless APs is the way to go.
also please note that mobile phone wifi hardware are not much good to start with, even if you get 20-30mbps on the different floor is pretty much good.

using mimo capable router with 3-4 antenna might help improve the speed, if you choose to do single single router setup.

+1
ayam using m5 also...good enough for me...no more ip conflicts, no more dead zones

Repeater and extender are usually shit. a powerline + a 2nd router or change everything to mesh wifi is better.

btw 9 mbps your dad can feel slow something else is wrong, more like instability of the wifi

Actually how do we connect the two nodes? Through wifi signal as well or through Ethernet port (say both floors got port, is it connected?).

Sorry me buta IT.

Multi repeater setup - this is cheapest solution.

Another solution is more costly, but both works well.

im using both, pull 1 LAN cable to 1 room, and another room use powerline adapter, best result if u pull the LAN cable.

Put additional AP in your parent's room. Set the SSID and password to be identical with the main router.

most ideal will be via ethernet port.
but wireless AP as a wifi client is not bad la, can say it is different level compared to what your laptop/semakphone have, so you can still enjoy high internet speed as long as the distance between those two router are not far with wireless connectivity between two routers.

Use repeater or extender.

If u have more budget, go for mesh, get 2 unit mesh will fix it

is either you go for mesh or add in additional repeater

Thanks.

Normally if the developer provided one ethernet port each floor, does the two ethernet port readily connected? For double storey house, is using 2 wifi mesh adequate? Floor area approximately 2300sqft.

~Park for updates too~

Will it work fine if I get Deco M5 and just try to set it up in the areas where the connection seems weak, i.e, at the kitchen/upstairs area?

since alrady have ethernet port, then can be easier. try trace where is the wire goes. potentially hidden in the stair case store room or near by the tv area.

if is connected, then just plug your cable into the router lan port, and the other side your laptop. once confirmed, plug in another router on your upstairs.

How big is the house? I only need a single router (Asus RT-AC86U) to cover my double storey house (20x70). Placement of the router is very important - try to find a centralized place for maximum coverage. I was planning for mesh too but wasn't sure if I really need one. So I bought an Asus which is Aimesh-ready, thinking I can get another one and link them together if needed. Turn out 1 is enough for me.

What's your budget and plan speed.

Thanks.

Use wiremesh for seamless connection.
