no address range available for DHCP request via wlan0

One of our boxes had a lot of the following errors in it's syslog.

daemon.warn dnsmasq-dhcp: no address range available for DHCP request via wlan0

We did once add a workaround:

Also see: Doodle3D/doodle3d-client#66

One thing that's weird about the workaround is that it checks for "192.168.10.249, lease time 12h" in the syslog, while, on boxes without issues we only see the following IP range in syslog

DHCP, IP range 192.168.5.100 -- 192.168.5.249, lease time 12h
