Reg: dhcp service unresponsive frequently

[Bill Shirley]

Run a tcpdump on the network interface looking for DHCP traffic. Are there any responses?
# IPv4
tcpdump -vv -e -n -i lan10 'portrange 67-68'
# IPv6
tcpdump -X -l -vv -e -n -i wifi 'portrange 546-547'

Who is handling your logging? systemd-journald? rsyslogd?
