Thanks, Gene. I agree very frustrating.
I’ll try moving it to the other SSID. I don’t entirely understand why it wouldn’t work as-is though, since the VLAN should be invisible to the device (I also have an EAP225) as the DHCP server is on the same subnet. But who knows at this point… The AP is plugged directly into the ER-X, so no intermediate switch (only the virtual one within the ER-X itself).
Other things I’m considering trying:
- Switch the IOT VLAN DHCP server to Pi-hole instead of the built-in one. See if it responds differently.
- Swap the VLANs over so the ‘default’ VLAN is actually the IOT one.
