I've only done limited testing, but I'm pretty sure that dnsmasq isn't starting properly with the latest toastman build (7462).
After router startup the router itself is not able to get the time via NTP. Nor are connected pc's able to browse the net. an nslookup on a client pc gives an error that implies that the router isn't responding to dns queries.
After logging in to the router and making any change on Advanced -> DHCP/DNS and then saving it will spring into life.
