disclaimer: i maybe way in over my head about this. the initial reason i asked was because i kind-of experience some problems with my own RT-AC87U router. it's an inferior model to yours, yes; i initially thought the firmware should be similar enough (since in practical business sense, having firmwares being too different from each other across different models cost too much money), so maybe i could use my log and compare it with yours to give some hints on what's happening on both our routers.
i opened both your syslog and mine side by side:
i have a wireless printer too, an epson LX 365 which is connected wirelessly to the RT-AC87U. what's different from yours is that when i first set it up, it was through a USB connection. several steps into the epson wizard, and i get the window to enter the wifi-ssid and password. this is when i know the printer would remember the ssid internally after the setup is done. plugged out the usb, turned the printer back on, tried wireless printing, everything worked (and still works) fine.
i avoided using WPS whenever i could, due to my inherent and perhaps irrational fear about that feature.
like you, i had problems with my own ASUS router prior to firmware update. it manifested when the router nagged me to update firmware. it was working flawlessly before, no matter how much load was thrown into it (4 people using it at any given time, along with their devices) . currently it's on firmware 3.0.0.3.380.7743 <- this firmware caused me some annoying inconveniences: abrupt restarts, killing all connections along with it. i had to wait for it to reboot for the network to re-establish itself.
i'm not a coder by any means, but... wthell, i thought. if we're gonna get ASUS to do anything, then i figured i better do the legwork than just entirely relying on them to fix this PoS (Piece of S***). some things i noticed between both our logs:
- when both our routers starts failing, this line keeps popping out:

... (took liberty to omit the rest of the logs)
but notice one thing, your router started its restart on 02:06:28, and from the log, i presume it finished shortly afterwards.
Oct 6, 05:16:10 -> 05:22:32 ----> it starts ****ting out tons of texts, most of which i have no idea what that means. but i know this line when i see it
"Oct 6 05:22:32 rc_service: httpd 2650:notify_rc restart_wireless"
when this line comes out on syslog, say bye bye to your wireless connection. then more kernel DROP happens (i have no idea what this is), until i suspect the router forced a restart.

Aug 1 03:00:13 syslogd started: BusyBox v1.17.4 <- and back it goes to Aug 1. i use this as my own router's bookmark. when i see the dreaded Aug 1, i know this piece of crap restarted itself.
the next thing i noticed was: your log timestamps was much longer than mine for every restart. the errors present in your router are worse than mine. my router could go back and re-enable wireless and wired if i waited long enough, but yours seem stuck with all the errors, and then it tried to restart itself again. this went on until Oct 6 05:51:56. look at your own log -> rc_service: wpsaide 534:notify_rc start_wps_method. looking at it, and by pure guessing, it seemingly tells me that it tried to restart WPS over and over and over but failed and tried and failed and tried and failed and tried till it gave up and it just attempted to restart everything at Oct 6 06:25:21 rc_service: httpd 548:notify_rc reboot.
this vicious cycle kept going on and on and on
😕i guess, just as a temporary measure. disable WPS entirely, and factory reset again with just one computer connected to it. see if that makes anything better, look at the log for any irregularities.
no siggy, saw stuff that made me sad.
