There is your problem:^^^^^^^^^^
What you need is 2 shared networks with individual names and their own
subnet entries.
Here is the relevant bit of my box doing exactly what you want ( 1
etherLAN and one wifi)
><8
shared-network LOCAL-NET {
option domain-name "witworx.com";
option domain-name-servers 192.168.80.1;
subnet 192.168.80.0 netmask 255.255.255.0 {
option routers 192.168.80.1;
range 192.168.80.80 192.168.80.99;
}
}
shared-network WIFI {
option domain-name "witworx.com";
option domain-name-servers 192.168.100.1;
subnet 192.168.100.0 netmask 255.255.255.0 {
option routers 192.168.100.1;
range 192.168.100.100 192.168.100.199;
}
}

It is good that you provided ALL the details. I wish more people would
do that.
