I have my deco mesh AP connected to a Layer 3 managed switch.  When I change from routed mode to wifi mode, the main access point fails to get an IP address and disconnects from the internet.  If I switch it back to routed mode, it connects just fine.  I am not sure what to do, I have ports configured as both a standard port assigned vlan tagged and trunked 802.1q ports.

In routed mode, the Deco is connected to a standard tagged switch port and it gets an ip address etc. and connects just fine and the mesh ap's connect with no issues.  

Only when I switch to WIFI mode, the does AP come up but does not connect and I cannot determine if an IP address ever gets assigned as I have no way to see this in the Deco APP for whatever reason.  Any suggestions or things that I can try....I would really like to have the AP's in wifi mode and not in routed mode..

The switch is a Juniper EX4200 I believe...  48 gig ports...fully managed etc..

thanks
