    What happens if you set a PC NIC with VLAN 10 and connect to port 5?

    is your router setup for VLAN 10?

    WIFIs SSIDs are assigned to VLANs. And all WIFI clients take IP access the internet etc.

    The issue is with the "PVID 1" clients, aka clients that are connected to non-vlan ports of the AP.

    So if I understand you right you need VLAN1 for port 5 to be untag? For untag clients to get a IP?

    So your router is doing VLAN1 as a tag?

    Yes.

    Router port 2 has VLANS 1,2,3 as tagged, connected to Switch port 1 which has VLANS 1,2,3 TAGGED

    AP has port 1 as VLAN 1,2,3 AS tagged, connected to Switch port 5 which has VLANS 1,2,3 TAGGED.

    WiFi ssids are under vlan 2,3 work just fine. From a any PC at the lan I can access the switch and vice versa.

    AP port 2,3,4,5 are untagged and have PVID 1. A

    ything that is connected to those portscan only talk to the AP, nothing else.

    PPlease not that I CAN access the AP (since traffic towards it is tagged)

    The only "solution" I find is to use untagged VLAN 1 on switch port 5. Only then I can access the devices that are connected to AP ports 2-5.

    I stocks on the Switch because if I connect a PCdirectly to any untagged port of the router I can access any device that is anywhere in my LAN.

    Red Lines: Unagged traffic (at least on paper)
    Blue lines: Trunks/Tagged traffic (at least on paper)

    For The default Vlan?

    What is the difference? No issue to test, I just want to understand the logic

    If you have a Zyxel AP then its set for VLAN 1 As Native VLAN meaning untag so if you uncheck that then it be tag VLAN 1
