Setup guest wifi on a dumb AP with VLAN (solved)

Installing and Using OpenWrt Network and Wireless Configuration
18

I think I have isolated this issues.
Due to the many changes and testing my /etc/config/network has changed at the 'lan' interface. After correcting the settings as below I have regained internet access at the AP.

The only function I cannot get to work for the guest wifi account is 802.11r (fast roaming) due to the guest network share the SSID but not the DHCP server anymore.

config interface 'lan'
        option type 'bridge'
        option ifname 'eth1.1'
        option proto 'static'
        option netmask '255.255.255.0'
        option ip6assign '60'
        option gateway '192.168.178.250'
        option ipaddr '192.168.178.253'
        option dns '192.168.178.250'
