Bridge WLAN and LAN on Sonicawall TZ100

So, By default out of the box the Sonicwall TZ 100 comes with separation between WLAN and LAN.  I have figured out easily enough how to open it up so I can route back and forth between the subnets that are set by default (LAN 192.168.168.x and WLAN172.16.31.x )

I would like to merge the two so I have a single subnet of 172.16.31.0/24 so there is no routing needed between WLAN and LAN and one common gateway.

Any suggestions how this is done is appreciated.  I was about to simply eliminate one of the subnets and just scope the DHCP for WLAN to issue IP's in a different part of the subnet, but I have a feeling it is more complex than that.  

Thanks

Honestly, we've got a number of these devices in the field now.  If you haven't gotten too far into the configuration, upgrade the firmware then reset to factory defaults and use the configuration wizard.  The wizard actually does a good job in handling the bridge between WLAN and LAN.

Oh, ok. I have not done much in the way of config so I will give that a go and report back.

I did upgrade the firmware which added the ability to brdige the two together in the wizard, this option had not been avalailable on the older firmware.  Now everything is on the same subnet and working great.  Thanks
