Did you find any solution to your packet loss problem on OpenWRT 24.10.0 other than to downgrade to 23.05.5 ?
I've recently installed 24.10.1 on my Linksys EA8300 & ASUS Lyra Map AC2200 Access Points, and i'm seeing pings on my LAN repeatedly jumping up from a few milliseconds to 250ms for just a short while before dropping back to normal levels. It happens randomly and doesn't even seem to be confined to just certain Access Points (although some are worse than others).
I posted here:

but it seems nobody has any suggestions that might help. Are you still on 23.05.5 ?
