Default VLAN (192.168.0.x) not getting IPv4 gateway, wired clients no internet but WiFi VLANs are fine

I’m running into a strange issue with my Omada setup and I’m not sure where I went wrong.

Setup:

- ER707-M2 (gateway)

- Omada controller (Docker)

- Starlink in bypass mode (WAN via DHCP)

- Multiple SSIDs assigned to VLAN 10 and VLAN 20

Issue:

- Wireless clients on VLAN 10 and 20 work normally (IPv4 and IPv6 both OK)

- Wired clients on the default VLAN (192.168.0.x) are having problems

On the wired PC:

- It receives an IPv4 address (example: 192.168.0.2)

- But there is no IPv4 default gateway assigned

- IPv6 works without issues

- IPv4 internet does not work at all

Ping results:

- ping google.com -4 → “Destination host unreachable”

- ping google.com -6 → works fine

What I’ve checked so far:

- DHCP server is enabled for the default LAN

- WAN is getting a valid IP from Starlink

I suspect I may have misconfigured something related to VLANs, but I can’t pinpoint exactly what.

Would appreciate any ideas on what to check or fix.
