VLANs would help maintain PCI compliance in small business where they have multiple devices plugged into the firewall or switch along with a card reader.
For this use case, since card readers do not typically support VLANs, the ports on the firewall or switch should be able to add and remove the tag as necessary. Also this use case would benefit by blocking all traffic between VLANs.

I tried creating a VLAN again today, and it worked!
I'm not sure if it was a firmware update (no way to see firmware version), or a reboot of the access point (I had to move it to another location).
