Thanks for your reply bro.. I'm not really familiar with IT stuff but let me try my best to answer as much as I can.
1. Main router is D-Link DIR-X1860Z AX1800 Wifi 6 router. Mesh router is D-link DIR-X3000Z AX3000 Wifi 6 router as well
2. I tried login once and yes I remembered there's such option to check on the signal strength, let me check that again tonight.
3. Child node means "secondary MESH router" and master node means "main router" I guess? Is there a way to check whether is our device connected to which router since both are sharing the same SSID? My main and secondary router are connected to each other using 5Ghz network, but when I scan for network, it shows one 5GHz SSID which i assumed it is correct, but there are two 2.4GHz SSID which sounds a bit strange to me, not sure if this is something normal.
4. Ok got it, have to try from one place to another place then
5. Yes, I'm on U mobile fibre 100mbps plan. When I'm right in front of my main router, it gets quite a decent speed in between 95-103mbps on both d/l and u/l. However when I'm in my room which I have the secondary mesh right in front of the room, it shows me signal drop to half with speed fluctuates. Anyway, I should have test the secondary router in few places to see which location works the best. Thanks anyway.

1. If u model is dual-band and not tri-band, even with good signal between the master and child nodes. The speed will still not be maximum when u are connected to child node. So tri-band or not does make a difference.
2. Ya normally the portal of the mesh wifi routers should allow u to check the strength of the child node to master node.
3. Yes. That’s the meaning of master and child node.
The same portal u can access for the mesh wifi router should also allow u to see which node ur device is connected to, be it master or child.
SSID depending u are using the same name for 5GHz and 2.4GHz or u will use the same name for both. Ideally u should use different name so that u can ensure that ur device is connected to 5GHz always for fastest possible speed. So if separate u should only see two networks one is 5Ghz and one is 2.4Ghz when u do the scanning.
4 & 5. Yes location u placed the child node very important, it affects speed u can get. Ideally it should be within the coverage of the master node.
Like my child node, the signal strength is full bar so my speed while connected to the child node is not bad and latency is low. Ensure that no more than 1 wall between ur child and master node. But also be cautious that ur master and child node also cannot be too close to each other Becos ur device may not switch to the child node that may be physically closer but instead connect to ur master node that is further away and result in slow speed and high latency.
I had made the trial and error of the positioning of the nodes to get the most optimised result now. I am using 3 nodes (including master) for my apartment unit of 882 sq ft. Now everywhere in the apartment I can get perfect speed and latency.
Besides, my mesh system is tri-band so it can archive this if not it is impossible.
