500 ports work, because they are left untagged. I changed the PVID of the ports that I want them to be tagged with 200 to 1 and it works now, but why does it untag when the PVID is set to the same VLAN? No other switch in my network does that.

The AP needs tagged packets for 200, 300 and 400 VLAN. It is already working on the TP-Link switch, but not on Zyxel. I have the port on Zyxel for AP set as it is in the attached screenshot below. Management VLAN is also 200. Uplink port is the same but is has also 500 set in the allowed VLANs which is used in other ports.

Hello, I have this problem now and disabling LLDP and rebooting the switch did not solve it. It works when I connect the device to another switch but not the zyxel one.
