if this is not the right place to ask for help, please tell me where that is.

i have four z9 minis that show any where from 33% to 50% packet loss when doing the ping test.

please let me know if these logs are normal or have an error and if they do have an error, what i need to do to fix them.

here are the kernel logs from each one:
