I am running the latest version of Asuswrt-Merlin.
My systemlog gets filled with entries like that :

Jul 20 18:52:38 dnsmasq-dhcp[1317]: Error sending DHCP packet to 0.38.0.0: Invalid argument

Is there a way to find out which device is causing this ?
0.38.0.0 does not exist in my network as far as I can see.
 
Did that, but still a problem.
But, now I get some more info :
Jul 21 10:53:04 dnsmasq-dhcp[826]: DHCPINFORM(br0) 0.38.0.0 02:0f:b5:e6:9b:44
Jul 21 10:53:04 dnsmasq-dhcp[826]: DHCPACK(br0) 0.38.0.0 02:0f:b5:e6:9b:44
Jul 21 10:54:09 dnsmasq-dhcp[826]: Error sending DHCP packet to 0.38.0.0: Invalid argument

Jul 21 10:55:03 dnsmasq-dhcp[826]: DHCPINFORM(br0) 0.34.0.0 02:0f:b5:57:ad:b0
Jul 21 10:55:03 dnsmasq-dhcp[826]: DHCPACK(br0) 0.34.0.0 02:0f:b5:57:ad:b0
 
Do you have a Range Extender/Repeater? If so, check it's configuration.
 
That could be a good point, working on it...
Btw, both devices are internet radios with a static IP, 10.0.0.38 and 10.0.0.34.

Then it looks like they are misconfigured because they're asking DHCP to reply to addresses 0.38.0.0 and 0.34.0.0.

I agree with the misconfiguration - both devices use the same network chip ( actually the same software ).
They are still reachable under the given static addresses.

For the time being I blame the devices.
 
It is definitely a device problem. Using DHCP makes the messages disappear.
Since the router can give them the same address each time, the problem is solved.
