The /etc/network/dhcpd.conf.uap0 configuration has the following for the network to manage.

subnet 172.21.0.0 netmask 255.255.255.0 {

When the users sets a base address using imwww we need to change this to use the network portion of the address. Since this is point-to-point (Iot device to monitor) we can always uses 24/8 for the network portion. So to fix this problem:

1. Move /etc/network/dhcpd.conf.uap0 to /etc/network/dhcpd.conf.uap0.template
2. Change the subnet IP from 172.21.0.0 to [BASENET]
3. Make php/settings-write.php:saveAccessPoint()
   1. copy the template to /etc/network/dhcpd.conf.uap0
   2. Swap the [BASENET] tag with the base address, sans host octet.

That way the dhcpd daemon can properly assign IPs to the sensor network.
