DNS Resolution Issue UTM9.3

Hello All, 

I am new this forum. I have migrated from Endian FW to Sophos UTM home edition. It has only been 3 days since I have done the setup but leaning to go to back to Endian, hoping I wont have to & some guru will help me. 

I have 3 LAN cards in the UTM, Internal LAN on 192.168.0.1/24 DMZ 192.168.100.1/24 & WAN connected to ISP.

I have set UTM as DHCP & DNS for my Internal LAN users, users connected via wired connection are kind of OK they get the IP & internet works but takes a little time to resolve external websites about 30 -40 seconds.

The wifi Users are the ones I am having great problems with, DCHP assigns correct IP but users cannot resolve any external websites- no internet access. so a computer/laptop will have right IP, DNS, DHCP, Gateway IP assigned

Just for info I don't use my ISP DNS in UTM, I have Google/OpenDNS forwarders set this is irrelevant.  

I have a read a few other people having similar issue but with older version I am wondering is it me who has done something wrong but that doesn't make sense because wired connections are able to browse the internet fine, ok, IP assignment is slow but works or it is the UTM which has a known problem.

Please help Many thanks
