Is the mesh backhaul over wireless or over wired ethernet ?
If wireless backhaul over a radio shared with clients, then you will loose significant bandwidth, usually about half in each direction.
It looks like you have a couple nodes too close to each other or at too high TX power at that measurement location. The last full entry for 5G-1 at -73 dB on channel 44 versus the first two on the list (each a different radio) looks about right. The first two 5G-1 may be causing problems for each other and client radios unless ASUS has some magic sauce going on. i don't know the ins and outs of ASUS's AiMesh so others will have to chime in as to what you can change. If AiMesh is automagically managing power levels on each of the radios, then much of the following doesn't matter.
If these were simple APs with ethernet backhaul, i would be 1) reducing TX power or 2) relocating one of the first two APs or 3) doing both. It is possible you may only need 2 , Main and node, but that will depend on the physical layout of the building. You can turn off all of the nodes and leave the main router wifi on and get readings on the main backhaul radio to determine a good location for the node. Anything in the -50 to -60 dB should be good enough.
What you are trying to do is locate the nodes relative to the main router so that they can communicate as fast as possible and have them far enough away or with enough obstacles between them so that they don't cause interference with each other. Ideally, you would want the measured power to overlap at -65 dB or less e.g. -70 dB between the two nodes . That will help force the client radio to look for a new AP and shift over to the stronger AP radio. Part of the issue can be that the client radio will still see the 2.4GHz band at too high of a power level (smaller -dB) and not want to switch.
Regarding the drop in speed test bandwidth, that is expected as you get further away and as obstacles like walls, doors, cabinets, etc are in the line of sight path. 2.4 GHz radios can penetrate a couple sheetrock walls and usually get acceptable signal power (> 65 dB ) but are lower bandwidth . 5GHz can penetrate 1 wall usually and offers higher bandwidth. Radio waves both penetrate and reflect off of obstacles. That can make it difficult for a client radio and AP radio to communicate at high bandwidth.
Even though the ASUS nodes did not change from the old house, the physical environment they are working in is different. So different results. Same for the client radios.
