I have port 1 on connected directly to the router. 

I also have a TP-Link TL-WA901N that is configured to provide 4 separate SSIDs.  Each of them is assigned a different VLAN:  100, 110, 200 & 300.  I've got it connected to port 2.  So that means port 2 needs to pass traffice for VLAN 100, 110, 200 & 300 through to the WAP.  It is my understanding based on what I've read in all the threads that I've found on the topic and all the guides I could find, that I should assign port 1 & 2 both as TAGGED.  This should allow the traffic for the all the VLANS to get through.  Correct?

Assuming I'm understanding this correctly, I've done that.  When I attempt to connect to one of the SSIDs on the WAP, the traffic isn't getting through -- it's as though the switch doesn't recognize the VLAN id's being passed to it from the WAP.  I'm wondering if it has something to do with the 

EDIT:  I forgot to mention that If I connect the AP directly to the router, bypassing the switch, my WiFi devices are able to connect without issue on the correct VLANs.  So I'm convinced the AP & router (pfSense) are both configured properly.

EDIT2:  There must be something wrong with port 2 on this device -- either hardware or in the firmware.  I reconnected the AP to port 3 instead of 2 and marked all the SSID VLANs to include port 3 instead of 2 as tagged.  Now all the devices are connecting fine.
