Do all intermediate switches need to have tagging for vlan to work?

I have an FWG and a bunch of Omada APs where I can set up vlans. However, there are two switches in between the FWG and the APs and neither of them have the ability to tag ports. Does this make it impossible to setup a vlan for my wifi IOT devices?

  Yes, it should work. (make sure these are gigabit switches, then you should be fine)

  Doesn't seem to work. In fact I can't even connect to the vlan endpoints. It's an araknis an-100 switches, so I'm assuming they don't passthrough tags.

  Do you have a consumer switch (netgear, tplink, linksys ...)?

  Only one and I'm guess both of them have to be consumer switches.

  The arakinis switch is not something we see very often, so really can't comment.

  But, in theory, dumb switches should just pass VLAN tagged traffic through them. (the VLAN tagged traffic may be bigger than normal traffic, but most of the dumb switches can do jumbo packets, so they should be okay)

  Any idea what else might be the issue? I created the vlan both in omada and in the firewalla and I made sure they referenced the same tag. The vlan in the firewalla specifies the port that is connected to the switch. Not sure what else there is that I might have missed.

  If you connect the TPLink directly to the firewalla, does it work?  (no switch in between)
