I don’t know if it will help, but you should enable debug logging for dhcp.
/system logging
add topics=dhcp,debug action=memory
Then watch the log for that client to renew the lease.
/log
print follow where topics~"dhcp"
What RouterOS version are you using?
Router Board RB750
Version 4.14
and problem is sloved as i changed the Ethernet card ![]()
