Thank you both! I will keep the Bluetooth coexistence mode off. As far as radius, I did check and the only mention I can see of radius is it's own tab under the wireless settings, can confirm it is disabled. I am wondering if the error is worth going through a full reset again? I might try and see if I can go back to Asus factory firmware and then reflash back to ddwrt this weekend to try to get a "clean install".
While it’s possible to switch back and forth from AsusWRT / Merlin and DD-WRT, I wouldn’t recommend doing it frequently or for just a settings refresh. Each time you go back and forth, you risk bricking the device as it reformats the flash and needs to be done in recovery mode. Not worth it in my opinion.
An “nvram erase && reboot,” followed up by either a “reset to defaults” in the GUI or WPS button reset will clear everything out. As I said upthread, it sometimes takes two or three passes to get everything back to defaults. At least that has been my experience.
Also, I’ll point out again to keep an eye on your configuration storage and to not exceed 64KiB.
Good to know! That command "nvram erase && reboot,” do I just paste that in the Administration > Commands box, then follow it up with full reset? I figure I've already come this far I might as well try this a few times then manually reconfig again
To be safe, issue the “nvram erase && reboot” from the command line inside a telnet or ssh session. Doing it from inside the GUI makes the web server (httpd) process the parent, and bad things can happen during a destructive operation when the parent process exits uncleanly, as in a situation where you run a command and immediately reboot.
The double ampersand “&&” is a shell logical operation that says: only do “Y” if “X” completed with exit status 0 (successfully). There are circumstances, however, especially when dealing with low-level hardware operations, where the system doesn’t perform the operation atomically. It would actually be better to add a slight delay to let the system flush any pending calls and hardware perform any I/O resets before you reboot: “nvram erase && sleep 10 && reboot”
Most of the time it will work without any concerns from the GUI, but the nature of asynchronous processing means that maybe the kernel kills httpd, for reboot, before the operation finishes, and Unix, in general, will terminate the running process if STDIN closes during execution, with certain exceptions.
Terminals are some of the lowest-level processes that run, and there are some exceptions in the code to prevent shutting down if child processes are still running, so safer to do it there.

Thank you both for the explanations, as well as reccommendations on next steps. This weekend I did multiple resets, maybe 5? I did a mixture of hard resetting nvram with wps button, as well as reflashing to latest version of ddwrt r50841, and eventually reconfigured from scratch. My nvram usage did go down at the end of the process, from 53kb to 50, however I still get random restarts. I am wondering if this is just end of life for the router. I am now thinking I need to look for a new router...I work from home and cannot have internet cut out randomly. Anyone have any suggestions? Preferably triband?

Try flashing a slightly older build, like from June ‘22 and see if problems persist. I personally think instability on this device has gone up since then, but at least you would have one more data point if it’s the hardware or not.

I think my next steps are going to be to try your suggestion of older build. Failing that, I'll try to revert back to stock firmware. If it still doesn't work I'll have my answer.
Please try, and also post whatever error messages persist in the system log.
Make sure you are also using the non-experimental firmware, as the experimental does not seem at all stable.
You can also try to reset to defaults and use the barest minimum config, of just SSID and WPA2 changes to see if parts of your config are triggering the errors / restarts. Also, in terms of restarts is the whole router rebooting, or just watchdog restarting the Wi-Fi and nas services?
There’s still some level of detail missing from the description of the problem.
When I went into syslog just now the logs only existed from the moment I logged into ddwrt and I had a wall of yellow, see below. Mostly though either the wifi seems to soft reboot, or the whole router reboots. Its difficult to figure out whats happening. I don't think I have any watchdogs running, except to reboot every 24 hours. The logs below are not what I normally find, usually its just 1 or 2 timeout errors, repeating over and over.

I generally have to set vm.swappiness = 1 as well to prevent OOMs in some cases.
But you shouldn't have to be tuning the kernel on a bone-stock config unless you are doing a lot of other tasks / network operations.
So, try the older build, if that works, you know it's the software's fault. Then maybe go back to current and try the tunables I just mentioned. However, if you see these errors on the older build and with a minimal config, I would hate to say, but it may be failed RAM.
What are your system temperature readings when the router is idle?

I haven't made any of the changes yet, I'll hopefully be able to in a day or so. But here is a screen shot of my idle temps:
I have loaded an older build, v3.0-r49049 std (06/02/22). Will monitor for issues. Off the bat, Im not seeing a timeout error, but I am seeing this new one that seems related to the GUI skin. I tried a different skin, error persisted. I have a wall of this same error, it is highlighted in red:
daemon.err httpd[2053]: [httpd] : Request Error Code 404: The file style/elegant/colorscheme.css was not found.
About your original problem, I do not know what you are doing with the router but maybe you are running out of memory?
Try to use a USB stick with SWAP file of 1 or 2 GB
Thanks I will see if I have a usb lying around but I don't think I do honestly. Looking at the picture above, I think I'm only using 25% of my memory, but I could be reading it wrong, or the router has memory spikes? As far as my config, it feels tame to me. I use a ddns service, and pihole setup using the sticky in the forum, example 1 from here https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=331414 . Pihole runs on a raspberry pi 4. The majority of my network traffic is wired.
