Use SSID in specific VLAN - Wifi connection can not be established

[VLANMaster]

Thanks. Now it works with your configuration.

To get this done via LuCI without editing config files with VLAN19 example:

1. Add vlan19 device
   Go to Network --> Interfaces --> Tab Interfaces. Click "Add new interface"
   Type eth0.19 and hit enter, then click "Create interface" and then "Save and apply". BTW: eth0.19 is only a common convention for establishing a VLAN with id 19. eth0.19 could also access vlan id 42, see https://wiki.archlinux.org/title/VLAN#Create_the_VLAN_device
   So OpenWRT just interprets eth0.19 as ip link add link eth0 name eth0.19 type vlan id 19

2. Now go to tab device and click "Add device configuration"
   Select "Bridge Device" as device type, give a name like "br-vlan19" and bridge port eth0.19, click Save and then "Save and Apply"
   

   

3. Now go to interfaces again, you see now a VLAN19 interface.
   

   

4. Click Edit button and change device to "br-vlan19".
   

   

5. Now you have a br-vlan19 interface (that was the missing step)
   

   

6. Now you can choose vlan19 at your SSID as Network and it will work. If not enabling and disabling SSID helps.

@Mods: Seems to work as soon as I flagged this as solution. No need to change anything of new user status.
