Router rebooting when downloading at full speed ( Xiaomi Mi Router AX3000T)

My router Xiaomi Mi Router AX3000T rebooting after few minutes during heavy downloading. Few month ago I bought fibre broadband 600 Mb/s, bought new router and installed OpenWrt, upgraded twice and now with 24.10.2 I have no problems during normal usage. Can download single file or torrent at full speed with no problem. But when I try do download few files or few torrents (specially with severals peers) router reboots. Disabling WIFI sometimes helps. Somebody suggested it could happen with too many connections but no idea how to check it, can't check LOG, it disappear after reboot. If anyone could help me understand this problem, I would really appreciate it. Not familiar with Linux also...

Are you running the torrent client on the router ?

Please post reference.

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

cat /proc/interrupts
# keep ssh session open while "downloading" to run these
sysctl net.netfilter.nf_conntrack_max net.netfilter.nf_conntrack_count
free

no, I installed only few statistic packages, just to check CPU temp

Thats for later

Connection problem suggested somebody from torrent forum but he was not familiar with OpenWrt.

Maybe just try a other power source, before diving to deep into the software part.

No worries, goid guess from them

1/10 of connections used, 1/3 of RAM.

Next:

install lm-sensors (and sensors-detect)

I already installed thermal statistics, temp was 65deg, 67 when downloading, now router is on case fan, cpu temp is now about 35deg.

Few min ago rebooted again tried to download torrent with about 25 peers

Run logread -fin a ssh session while downloading, maybe it catches something. Temperature is very good, hope your living room is warmer than that, no shortage of “numbers of connections”

I agree with @Yip. The symptoms are consistent with a failing or marginal power supply.

Yep, everything of software side and thermal conditions is nearly ideal.

This is apparently wifi problem, so I disabled wireless and downloaded 300GB with multiple torrents with no problem. However it is weird, somehow downloading collide with wifi. Thank you for your help so far, I've been trying to check the log for weeks and I failed:).
Now what's causing the problem?

wifi country code highly recommended though not related to crash.

Looks like short power, such spurious crashes should have been noticed in years filogic platform is supported.

Power supply? I can check and try another one if I found

With new power supply (30W instead of 12W) nothing changed, I still have reboots. I noticed message "ieee80211 phy0: Hardware restart was requested" doesn't force reboot, after some research I find out it restart wifi. In LOG this message appeared several times and nothing happened. Here are few last lines from LOG with memory error just before reboot:

I find out also wifi reboot is requested after

it could be related to wifi driver bug, someone suggested multicast-to-unicast problem.
After starting the download, authorization messages start appearing:

Disabling only 2.4 GHz wifi (with about 20 devices connected) and enabling 5 GHz (5 devices), somehow helps, restart request almost every few seconds but no reboots.
