try and add  switchport trunk native vlan xx

I have a semilar config and it work. remember native vlan dont need vlan config on ssid.

my config

 description AP1
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 60
 switchport trunk allowed vlan 1,60,200
 switchport mode trunk

you should also remove spanning-tree portfast, no need for that on access point, anly use that on singel host. (Printers workstaion and so on)

  @MR.S if i add the native vlan in my case 100, for management, the management port is not working any more, the only option is to set the native valan to 1

  @SoulRaven 

do you use controller or is ap in stand alone?

standalone, AP->cisco switch to mention that the same config i use on 3 openwrt AP's and is working absolutely OK, with no other intervention. Is like the tp-link FW is not knowing about trunk.

what firewall do you have? and how is switch port config to firewall?

  @MR.S between the AP and the switch i don't have anything.

as a router, IDS, firewall, dhcp i use pfSense, and all the vlans are avalibile, the others AP and servers and evething is working just fine, the EAP255 is not workis as expected.

ok, my suggestion is to add this line in config 

switchport trunk native vlan 1

then set managemnet vlan on AP, in theory this should work, mybee 

  @SoulRaven 

mybee I miss somthing here, what is the exact problem. is it managment vlan or is it ssid dont work on vlan 1 and 14

  @MR.S the vlan 1 and vlan 14 in my case are not working.

Any combination of 2 vlans is not working, if i set the access vlan 1 or 14 is working one of them, but in trunk mode no vlan is working. the only constant is the management.

Is like the AP is not know about trunking and the trunk and the management is send as different traffic.
