Reference: [Solved] RT-AX53U Bridge/VLAN Config
This got me working just fine with the RT-AX53U, but attempting to get the same VLAN setup working on the Dynalink leads to losing connectivity every time as soon as I apply the VLAN config. I am running RC2 (and not the snapshot), which has Luci built-in and the install itself was pretty straight-forward -- but I am once again pulling my hair out attempting to get two VLANs to work (the base, Vlan 1 but don't care as its untagged) and then on Vlan 3 for the guest network.
Its a different hardware base in the switch, but you'd think it would be basically the same in both cases -- but it isn't, and what worked perfectly well for the RT-AX53U doesn't on this device. Trying to do it entirely through Luci fails, as does editing the config file by hand; both lead to the same result.
In fact, just setting "u*" for VLAN 1 for the br-lan interface, which should default it to untagged, VLAN 1 leaves me with nothing immediately at all when connected to a standard PC on one of the LAN ports; after the 90 seconds with Luci it reverts of course.
Is there something odd with the WRX's switch involved in this?
