Hello
when ping goes down check your interface traffic.
maybe anyone send big traffic to your router.
some times i found this like in next pic

but the ping still reply and ok no time out
time out come suddenly plz help
i checked your send image
i don’t see any abnormal thing in that picture…
hey
how there is no abnormal
look to tx and rx in wan and lan again
Hi
i am sorry but i don’t know about your problem…
deny icmp packets except echo request and config filter rule for deny ping flood and then check your MikroTik for timeout.
plz tell me how i deny all ping request exept echo (( what echo mean ))
and ping flood how ??
You should do a check that one of your lan pc’s is not : route poisioning your lan
The effects you descibe, are similar to an experiance I have had with route poisioning the arp table.
My cause was the mikrotik hotspot was doing the R-Poising by default to stop un-authed devices traversing the lan.
THIS IS MY PROBLEM
