WLAN 802.1Q support

Could please anyone confirm me if the model SOHO supports the IEEE802.1Q standard in the WLAN connection.

I am planning to change my ISP and with the new one I will need to configure the WAN connection in PPPoE with the following parameters:
PPPoE user
PPPoE password
VLAN Priority.

The WAN configuration of SOHO in PPPoE has the fields for the three first parameters but there is no field for the VLAN Priority parameter.
