Hardware Version: V2
Firmware Version: 2.2.3 Build 20250723 Rel.05551

I want to set up WAN/LAN3 as a backup WAN in case the main WAN fails, but there is no option to select WAN/LAN3 in the backup WAN drop-down menu. I am attaching screenshots for reference. I found a similar topic regarding the ER605 model, but the solution provided there does not help

  @Kamillll Would it be possible to enable and disable the USB Modem port as well? Also, was this feature previously working or is this the first time configuring the Link Backup feature?

There was no need for this before, so this is the first backup configuration. The USB modem port can be turned on and off, but it is not visible.

Thank you for your post. Have you tried using a different browser?
Also, please attempt to disable and re-enable the WAN/LAN3 port several times, or remove its configuration entirely, reboot, and then re-configure it from scratch.
In addition, is WAN/LAN3 included in the primary-WAN list?
Finally, double-check that load-balancing is correctly enabled.

  @Ethan-TP Of course, I tried using a different browser and a different computer. I turned WAN off and on several times. I restarted the router. I reconfigured the WAN network. For example, when configuring VPN, I see WAN3 (screenshot). How can I check if I have configured load balancing correctly?
