Hello,
Each time dnsmasq leases an address a message like the one below is added to the log:
2021-08-08T18:08:59+02:00 lgrrutx dnsmasq-script[3754]: command failed: No such device (-19)
The source is in /usr/sbin/dhcpinfo.sh:21, iw dev wlan0 station dump fails if wlan0 doesn't exist which is the case if wireless is disabled. Added a simple test to get rid of the spam:
iw dev | grep wlan0 >/dev/null 2>&1 && conn_inter=`iw dev wlan0 station dump | grep $lease_mac`
Regards,
