Can't make VLAN work in the Bridge VLAN tab as per the screenshot, no matter what I do, once I press save & apply can't connect to Luci. Tried different VLAN id's: 1, 101, etc.
But a separate soft VLAN (802.1q) device like lan4.1 works.
There are several videos linked on the dumb access point wiki page that you may find helpful whether you are running a dumb AP or not. Recommend you review them.
For reference, here is my Archer A6's config. The A6 is being used as a managed switch keeping my
Lan1 and Lan2 are on VLAN 10 (lan zone)
Lan3 and Lan4 are on VLAN 4 (guest zone)
WAN is the uplink port
Re-flashed latest Openwrt release (22.03.03), reset the router.
Tried untagged with and without Primary VLAN ID, also tried as per your screenshot adding wan port to the bridge: no result, each time loose connection to the router and revert to default.
As if something is broken with VLAN filtering.
What version is your A6 ?
Did you do any other changes in Interfaces -> Devices tab?
Before you click ‘save and apply’, are you changing the device for the network interface to reflect your newly created vlan? I made this mistake when I first attempted setting up vlans using DSA.
Create the vlan and tag/untag the necessary ports
Click ‘save’, NOT ‘save and apply’
Go to your interfaces tab and change the device for the appropriate network interface
