Hello,

I would like to describe the objective I am trying to achieve.

I have two internet service providers. One should be the primary (WAN1), and the other (WAN1/LAN1) should act as a backup. When WAN1 loses internet access, the router should switch to the backup WAN1/LAN1. If the primary WAN1 regains connectivity, the router should switch back to it.

Unfortunately, the router is behaving differently than I expect. Perhaps I have configured something incorrectly? I really don't know. Everything worked fine before. The issue likely started after updating the Omada controller to version 5.13.30.8, but I am not certain.

Currently, the situation is that if WAN1/LAN1 regains connectivity, the router switches to the backup connection even though WAN1 is providing internet to the router. Last night, the router unexpectedly switched to WAN1/LAN1, even though WAN1 was fully operational. There are no logs indicating any issues with WAN1. The only log was that WAN1/LAN1 was temporarily inactive but then regained connectivity. It was at this point that the router switched to WAN1/LAN1.

Now, it seems like WAN1/LAN1 is treated as the primary connection. If I disconnect WAN1/LAN1 in the Omada app on my phone, the router switches to WAN1. If I reconnect WAN1/LAN1, the router continues to treat the backup connection as primary. Why is this happening?

Unfortunately, I cannot attach screenshots here (403 ERROR .The request could not be satisfied.)

Thanks
