On the Basic Setup page I have unticked Use dnsmasq for DNS and that works fine as far as the DNS is concerned. However, it seems that dnsmasq is still used with the DHCP server. Unless I disable the DHCP server, the Dnsmasq Infrastructure on the Services tab stays with Enable dnsmasq enabled and that cannot be changed. If I untick there the Enable dnsmasq option and apply/save, it appears saved but leaving this tab and coming back to it I find the value has reverted back to enabled. Also, looking at the running processes with the SSH top command, I can see that dnsmasq is running.

My question is: can I use the DHCP server without dnsmasq? And if so, how to achieve it?

Basic Setup > Dynamic Host Configuration Protocol (DHCP) > Use dnsmasq for DNS = disabled

then the clients do not get the address of the dnsmasq server via DHCP but a server that is configured under "Static DNS".

I did that and indeed the DNS servers passed on to the clients are the static addresses that you mention.

However, it seems that dnsmasq still continues to be used. The Dnsmasq Infrastructure on the Services tab stays with Enable dnsmasq option enabled and that cannot be changed.

Also, looking at the running processes with the SSH top command, I can see that dnsmasq is running.

So, to rephrase my question: why is dnsmasq running and can I disable it completely?

Because dnsmasq is also the dhcp server.
