That would be my preference, but I don’t think it’s possible. Not sure how DD-WRT does it, but it seems to work using the NSS engine on both parent and child devices. At least, when I was using DD-WRT, CPU and RAM usage were low enough that it appeared to be using NSS.
I have Mx4200 V1, getting wifi calibration timed out.

I think @BrainSlayer can confirm or reject your thoughts.
Hah, I didn’t realize BS was active on the OpenWRT sub. I figured I’d ask on the DD-WRT forum if I decided to leave OpenWRT.
nss is optional in dd-wrt you can enable or disable it on demand on the basic setup page. but in no way it has effect on resources or just minor effects. but i spended efforts in optimizing everything for best effort based on my own test results. i also provided back patches and findings to qosmios nss tree.

i’m some sort of active as contributor even if i’m mainly focused on dd-wrt. but its a fair if i give something back since i also use patches from openwrt

So I’ve run into similar issues, @kevzz01. On one of my three MX4200 v1 units, trying to upgrade or flash would throw it into a flashing green LED, and I’d have to triple-boot it to recover. Weirdly enough, the other two units upgrade just fine via attsysupgrade or OWUT (I prefer OWUT) without any problems.
I haven’t tried going back to stock OpenWrt then upgrading from there, since the other two behave normally and that workflow feels like extra hassle. I’d love to dive deeper into mesh and get it working smoothly, but I need to get past this issue first.
I looked at the NSS build, but it was missing a few things I need for simple AP mode, so I skipped it. I will say memory usage seems to be improving with newer builds, although that might just be me hoping.
Hopefully I can find time soon to reflash/restore/reconfigure the main AP and do some more testing. Maybe @dandek01 has ideas before I go full-nuke on this one?
The problem you mention may be caused by having OEM firmware on the second partition during installation. This has been resolved, but it seems there are no official 24.10 images yet that include this fix: https://github.com/openwrt/openwrt/pull/20086
Isn't it in 24.10.4? It's specifically mentioned in the release logs.
Your upgrade patches were committed on 10-16; 24.10.4 finalized on 10-20:
Yes, you're right. I missed that release 
@5H3RM What version of OpenWrt are you using?
Don’t nuke them, they can work. I’m using vanilla openwrt on them 24.10.4 with 80 mb of swap, install zram. it is somehow sweet spot for them not to go oom.
I’m using them as dumb ap in batman with firewall, dhcp disabled and that maybe help as they are used as transparent bridges. I tried to build nss and install it on mx4200 but it didn’t want to bring mesh link up so i booted back to vanilla. I think that they can be definitely used as dump ap and transparent bridges in batman. I just don’t use vlan ssid on them because it triggers oom.
If you take a look at the nss-config.seed there is actually some steps listed out on the top.
Do you have a copy of your configs? BTW batman-adv is completely different mesh protocol compared to 802.11s (which is what NSS can accelerate). So adding that in will very likey break acceleration for you.

Thank you
BTW
batman-advis completely different mesh protocol compared to 802.11s (which is what NSS can accelerate). So adding that in will very likey break acceleration for you.
I appreciate the heads up. I don’t actually want to use it because I feel like I can accomplish what I want using 802.11s, but I’m clearly missing something (probably something simple).
Do you have a copy of your configs?
I do! I assume you just want network and wireless, but let me know if there’s more to share. To summarize: APs and VLAN APs work on the parent device. Only APs work on the child device (connecting to a VLAN AP on the child device never hands out an IP address).
Thanks for taking a look at this! I can’t imagine this is an uncommon configuration, but most of what I find is folks saying wireless backhaul sucks and folks should be using wired (which I agree, but it’s not feasible here).

The one device that’s giving me issues is on 24.10.2, all the reset are on the latest. I did a little more troubleshooting today (flash to vinalla openwrt, upgrading with file from another AP, upgrading to stock openwrt) and nothing is working. I’ll look into the partition thing a little more. I do remember one time trying to mess with them when I first got the MX4200 and maybe this is where I went wrong. Maybe I'll try Linksys stock and reflash that way. I’m not sure what else to do.
Edit:
Ope I bricked it trying write the kernel on both partitions. Now when I reboot its just solid blue.
Try to plug it in for 2-4 seconds and then plug it out. Do this 3,4 or 5 times to force it to boot from another partition.
In version 24.10.2 sysupgrade will fail if the second partition has OEM firmware. You need to install factory image using mtd: https://github.com/openwrt/openwrt/pull/13432/commits/46a2490e8f24a1ad47e53b0b4ee875fa3658f2c1

I’ve tried many times, even holding the reset while booting to make it boot to another partition or recovery. Still nothing .
This is what i did when I bricked it. But I did custom firmware on both and now I'm pretty sure I’ve lost a way to connect with the device via ethernet. There isn’t much info on TFTP setup, but I tried what I knew and couldn’t get it to work but I could have been doing it wrong too.
To recover the device using tftp you need access to the serial console: https://openwrt.org/toh/linksys/mx5300#tftp_from_u-boot
I suggest you configure USB recovery options for the future: OpenWrt support for Linksys MX4200 - #2059 by lytr

I have an issue with 1 of a pair of mx4200 v2 I have currently running 24.10-SNAPSHOT r28477-51594ca508 / LuCI openwrt-24.10 branch 25.037.68331~42f464c
NSS build I compiled earlier this year from Qosmio’s repo.
it appears 1 AP detects DFS radar for radio0 and shuts down. It has done this quite a bit recently.
My understanding is that it should check and renable / move chan but clearly it doesnt.
Currently manually set to chan 60 / 80mhz bandwidth
I am happy to scan and use a different channel but this also seems to indicate an issue with expected behavior too ?
