Is dnsmasq running on the router where the old DHCP software was?  A
separate computer?  Connected how to the network? (e.g. dnsmasq is
wired to the router, clients are a mix of wired and wireless)

What OS?  Could be a firewall/packet filtering issue on either the
dnsmasq computer or the router. (e.g. router firewall is configured to
accept DHCP requests but not bridge them to the rest of the network)

Make sure that dnsmasq owns port 67 on its machine by running "netstat
-l" with dnsmasq running and again with dnsmasq stopped.
