@rumblpak did you try to configure a switch port in the same VLAN as the SSID you are trying and see if it worked that way?

Also, please give details on how the Plex server is connected to the network.  I assume wired.  What is the config on the switchport it is connected to, how is it getting it's IP (DHCP or Static)?  What is the mask? (255.255.255.0?)

How are the clients connected (I assume Wi-Fi).  I also assume DHCP, and that it is pulling an address in the correct scope.  What is the mask?

What are the VLAN Default Gateway IP's, and the DHCP range for each VLAN?  I assume 24 bit masks (255.255.255.0), but please confirm.

What is the topology of the network? 

Is this the topology for Clients?

Modem -> Router -> Switch -> AP -> Client

Server?

Modem -> Router -> Switch -> Server

What make/model of switch and router?

At this point I feel like I must be missing something obvious, but I don't know enough details to know what that obious thing is.  

  @rumblpak I can't help without details.  Happy to help though.  Work through my last post and answer those questions, and I can take a look at it.  I don't need public IP's, just stuff within your local LAN.  Screen shots are always helpful too.  IE: for the port configs on the switch ports, and VLAN definitions.

> Nothing really of note here, before making changes, the port defaulted to vlan1 untagged and required vlan11 to be tagged (which should have been done by the setting on the AP). Changing it to be vlan11 untagged and require vlan1 to be tagged and setting the AP to have a management vlan does fix that but it should still work the other way.

  @rumblpak You'll probably want to reach out to Omada support.  Assuming everything is configured as you say, I see no reason it shouldn't work.  I don't know much about the Micotik router, but I have used Omada AP's with Cisco (Enterprise and SMB), Omada, and Ubiquity hardware with no issues.  Even used them with Zyxel at one point.

  @rumblpak Got back from vacation and saw a new firmware got released, based on the release notes: https://static.tp-link.com/upload/firmware/2024/202401/20240102/EAP683%20LR%20v1%20Release%20Note.pdf it probably fixes the issues I'm running into, gonna update it and will report back (may take a few days as I'm also moving).
